Horning Eufrodite Ellipse PM65 speaker
Having made a British designed and made pair of horn speakers the subject of my first review for Dagogo, I subsequently attended the UK National Audio Show at Whittlebury Hall, just up the hill from the British Grand Prix circuit of Silverstone.
Curious to discover other European manufacturers taking a horn-based approach I visited LW Audio’s room at the show where proprietor Iain Borthwick was demonstrating a pair of Horning Eufrodite Ellipse PM 65 speakers. The Danish speakers were being driven by Chinese designed and made 120 Watts per channel Audio Music 833 monoblocks. The Eufrodites sounded pretty good and looked interesting.
Several weeks later, Iain delivered the Horning Eufrodite Ellipse PM 65 to my home. My wife’s face fell when she saw them placed on the carpet in our listening room. “Oh. Those are big. I hope they’re not staying.”
Well, I guess the Hornings are big by the standards of some speakers, but not big by the standards of others. Everything is relative.
I think I know what she means though. She’s used to the Audio Note Es that huddle discreetly in the corners of the room, and even though Horning Eufrodite designer Tommy Horning intends his speakers to be put similarly close to the corners, that proved impossible in my room. The result of such placement was a massively muddy sound, boomy bass and almost no top end. It was only after moving the Horning Eufrodite Ellipse PM 65 around for some twenty or so minutes that Iain finally declared himself satisfied with the sound.
The Eufrodites are not the first full range speakers to be troubled by my listening space. It is just over 21 feet long and 12’ 6” wide, but it has a low ceiling at just over 7 feet. Audio Note Es of various levels work exceptionally well, as do Acoustic Energy Reference IIIs, to name but two examples. Big ProAcs, B&Ws, Vandersteens and PMCs have all to a lesser or greater degree required careful positioning to dial out as much as possible the easily excited bass room nodes. Some – most notably the ProAc 3.8s – just never settled. However, with their front baffles 51 inches from the front wall, and toed-in to cross in front of the listening position, the Horning Eufrodites sounded much more at home.
This raises the question of whether I should have abandoned the review and simply returned the Eufrodites to the UK distributor who had gone to so much effort to deliver and set them up. Let me answer that in this way. My room is not a one-off. There are many audiophiles whose listening spaces are, like mine, divergent in one way or another from what Cardas describes as having a golden ratio. In the context of an overall positive review, I point out aspects of performance that may cause readers similar problems if, as in this example, their listening space shares similarities to mine.
Give Tommy Hørning his due; in one way he has been nothing if not consistent for over a decade now. The Horning Eufrodite Ellipse PM65 speaker was launched in 2002 and since then he’s tweaked and plucked, refining the same essential layout; the current model that I auditioned being the MK 5.
It’s excusable to be in two minds about this restless search for perfection: on one hand we might applaud the determination and refusal to settle for ‘good enough’, but on the other hand owners of earlier Horning Eufrodites, seeing the value of their purchases undermined by the launch of successive new models, might have a less than approving response.
It has to be noted too that the Horning Eufrodite Ellipse PM65 speaker has escalated keenly in price – a stout difference of some $8,000 separates the Mk IV and the current model, launched just a few years apart. Tommy Hørning would surely counter – and with some justification too – that the Ellipse PM 65 is considerably more costly to make than the earlier versions of Eufrodite. Not only does it use a larger and more expensive Lowther driver, the cabinet is more complex and thus more expensive to manufacture also. Finally, there has to be factored into the MSRP a reflection of what the designer believes is the sonic performance comparative to alternatives at a similar price point.
The Horning Eufrodite Ellipse PM65 stands 48 inches high, 13 inches at their widest point and 23 inches deep overall. Viewed from above, the sides of the cabinets are elliptical, narrowing at the front baffle, and at the back too, to just 9 inches. They are executed in ply and MDF with internal bracing. Each weighs some 140 pounds, so are not trivial things to unbox and move around. They are supplied with composite rubber-like feet, but Tommy Horning is resigned to the inevitability that buyers in countries other than Denmark will likely prefer spikes or other supports. The front baffle has a removable cloth grille from top to bottom that is just 7 inch wide. Combined with the very attractive apple wood veneer that my review pair came in, the narrowness of the front baffle and even narrower grille really do help to minimize the visual impact of the Eufrodites. Even though they occupied useful floor space in my listening room when positioned forward as they had to be, I did not feel that they had an overwhelming presence.
The tweeter chosen by Tommy Horning for the Ellipse PM 65 is a lightweight spiderless design modified with a larger magnet to get the efficiency up to 99dB. “It goes over 20 KHz and is in my view far better than any ring radiator or dome tweeter,” he says.
The midrange unit is a Lowther PM 65, and no, you won’t find it on Lowther’s product list. It’s a 6.5-inch driver with a 2.45 tesla alnico magnet and a dynamic mass of just 5.5 grams. Standard 6.5-inch drivers are designed to work over a 30 Hz to 22 KHz range, but Horning removes the whizzer cone from the centre of the driver and glues in its place a cloth dust cap, resulting in a unit that rolls off acoustically at around 6 dB per octave below 200 Hz and is integrated with the tweeter by use of a single Jensen capacitor at a crossover point of 12 KHz.
Look at the rear of the Horning Eufrodite Ellipse PM 65 and you’ll see the substantial cast baskets and magnets of four Beyma 8-inch woofers arranged vertically in close proximity to each other, pulled up against inlet holes on the rear of the cabinets by a cage tensioned with steel bolts. Not visible are four more identical drivers inside the cabinets arranged so that the eight units in total face each other across the void of a quarter wave horn. The two banks of woofers fire in push-pull, 180 degrees out of phase.
The horn is just over 8ft long with its rectangular mouth located just above floor level at the rear of the cabinets. It is acoustically elongated by 10% by the use of additional compression at its blind end. The horn loads the Beyma drivers but it also loads the rear output of the Lowther PM65 , too. What the listener hears is therefore the sum of direct radiation from the tweeter and the Lowther, integrated with the horn-loaded rear component of the Lowther and the push-pull woofers. All that complexity; yet just a single capacitor for a crossover. “The rest of the integration is done acoustically,” confirms Horning.
What drives him to such complexity is his wish to achieve full range horn-like speed without the major downside of pure horns – primarily that of the size required to get convincing low-end performance. Do it all with horns, as a purist, and what you end up with for the bass is a long horn, as in many yards long, and that in turn means a cabinet that is about as living-room friendly as a juvenile elephant. And since we’re talking stereo – make that two juvenile elephants.
Quite a few speaker designers wanting to buck the inescapable physics use horn-loaded compression drivers for the tops and mids, but combine them with conventionally ported or infinite baffle cone drivers – 10-inch, 15-inch and sometimes larger still – for the lower frequencies. Horning’s assertion is that this is a compromise doomed to failure and that it simply leads to irreconcilable integration incompatibilities.
Horning’s alternative approach is therefore to use a shorter horn but employ big surface area. A 15-inch driver has a surface area of approximately 176 square inches, but the Eufrodite’s eight times eight-inch drivers have a combined surface area more that twice that – a whopping 400 square inches.
Horning arranges his eight woofers in push-pull so that not only is there a lot of control over excursion – each cone moves just about 1mm even when driven hard – but the smaller magnets required compared to the large carbuncle on the rear of a large cone are much more responsive to input from the power amplifier. They therefore exhibit a far lower propensity to break up and distortion than would a single, larger speaker with a cone made of the same material.
Because it has a necessarily small mouth to fit within the width of the cabinet, the Horning Eufrodite Ellipse PM 65’s horn behaves as a transmission line at the lowest frequencies, transitioning to true back-loaded horn behavior as frequency rises. It also performs best – in rooms with an ideal ratio of ceiling height to width and length at least – when the speakers are placed close to the room corners where the acoustic impedance of the horn mouth is reinforced by the boundary.
This explains why Tommy Horning recommends corner placement and how UK distributor Iain Borthwick reports ‘prodigious’ bass without boom or overhang when using the Eufrodites in his high ceilinged 12’ X 12’ listening room. What I’d heard at the National Audio Show was a tight and deep bass that was tuneful.
Iain Borthwick was in no doubt that the low ceiling of my listening room prevented the Eufrodites from performing at their best and delivering an impressive bottom-end. However, having put people to the trouble of long distance delivery, and being personally intrigued by the speaker’s design, I decided to press ahead and do the subjective review anyway.
I drove the Horning Eufrodite Ellipse PM 65 with my Audio Note UK Kegon 18-Watts-per-channel 300B PSE monoblocks, speaker cables connected to the amplifiers’ 4 Ohm taps. The Eufrodites have a claimed 98 dB efficiency and present a claimed flat 4 Ohm load over their frequency range. Although I was unable to verify this through measurement, the efficiency figure feels broadly right to me – they played two clicks louder than my Es for the same volume setting.
The immediate sonic impression the Horning Eufrodites give is of grand scale and detail. The tweeter and mid range drivers are considerably higher than the ear of the seated listener, and they create a sound cloud that billows high and wide, beyond the cabinets in every direction. Pulled forward into the room as the review pair had to be, they were detail meisters, delivering a really remarkable level of micro dynamics that gave acoustic folk and jazz a very appealing and intimate feeling. They didn’t make anything acoustically larger than life. Solo voices and acoustic instruments were tightly drawn in space and were a believable size. However, when I played my copy of Beethoven’s Fifth Piano Concerto, Radu Lupu and the Israel Philharmonic Orchestra under Mehta, the Horning Eufrodite Ellipse PM 65 threw a sound stage that was simply enormous, taking me by the scruff of the neck from my usual Audio Note E position of two thirds of the way back in the auditorium and plonking me down up at the front, nose to the stage, right behind the conductor and in close proximity to the orchestra.
The Lowther mid-range driver and the tweeter are extremely well integrated giving a soaring, sparkling top end that is sweet and grain-free. Tommy Hørning has worked wonders on the mid-range driver, taming the Lowther house sound which unkind critics sometimes describe as nasal, giving us a midrange that to my ears and in my room was even and without obvious colouration, even if with some recordings it had a tendency to sound slightly thin in comparison to my reference Audio Note Es.
The performance of the speakers below 200Hz where the eight horn-loaded Beyma drivers are working together is also worthy of particular note. The expectations brought to the business of a subjective review are frequently validated by the listening experience. Not so in this instance, though. Although the positioning of the Horning Eufrodite Ellipse PM65 speaker in my room was compromised, they were audible (just) at 30 Hz, and then developed strong energy from around 40 Hz all the way up to the acoustic crossover point with the Lowther. I’d been expecting a clash of the cones, so to speak; a blurred or slurred bottom end resulting from multiple drivers all trying to do the same thing but not quite succeeding. However, I ended up being blown away by low end detail portrayed cleanly and convincingly. Stanley Clarke’s electric bass on “Return To Forever’s” live double The Mothership Returns was rich with such a level of harmonic detail and nuance as would bring tears of joy to the eyes of many music lovers. The Horning Eufrodite Ellipse PM 65 have a truly remarkable ability to portray texture at this end of the audible spectrum and Tommy Horning’s decade-plus-long quest to refine the concept of multiple push-pull units has not been in vain.
A question that many will ask, looking at the three different types of drivers used in the Horning Eufrodites, two of them horn/transmission line loaded and one not, and the way the handover between them is implemented, is do the Eufrodites sound coherent in the time domain or does the bottom end feel like it needs to play catch-up with the mids and highs?
That’s a tough one for me to answer in a way that’s fair to the manufacturer and which doesn’t mislead potential purchasers. It’s tough to answer because what I heard on some material was a bass that did feel to me like it could have done with arriving at the party a little more promptly. Side two of Jean Luc Ponty’s 1989 recording Storytelling opens with a track in which bassist Baron Browne plays the first few bars slightly behind the beat against a backdrop of snare drum, shaken tambourine bells and simple keyboard figure. Through my Es, and indeed other speakers I’ve had in my listening room this slack timing is evident, but not glaring. However, the Horning Eufrodite Ellipse PM 65 made it very plain and actually quite discomfiting to listen to.
The question is did the Horning Eufrodites unfairly highlight it, or did they tell it like it is? And if they highlighted it, did they do so because the positioning in my listening room meant the horn in each Eufrodite was insufficiently loaded to perform as Tommy Horning intends? Certainly, there were no apparent issues when I listened to the Eufrodites at Whittlebury, and nothing else I played in my listening room led me to focus on the timing in quite such an acute way. My overall listening impression was of a well-developed speaker that combines speed and directness in the presence region with good tonality and an almost forensic presentation of the sound stage. That’s a package that I know will appeal strongly to a lot of potential buyers.
UK distributor Iain Borthwick describes the Eufrodites as the most musical speaker he has heard, and, despite their undoubted efficiency, he says they give of their best when driven with some Watts. As companion amplification he rates very highly the Audio Music 833 monoblocks that he sells, and also uses at his home.
In contrast U.S. distributor Jeffrey Catalano of High Water Sound has demonstrated Horning Eufrodites driven by 2A3 flea-power – and been awarded best sound in show for his troubles.
So what does all the foregoing tell prospective purchasers that might be useful about the Horning Eufrodite Ellipse PM 65? Well, I think it is pretty safe to conclude that they deliver of their best when placed in a corner as their designer and maker Tommy Horning intended. But they also need room to breathe, and in particular they like a high ceiling.
It’s probable that if the listening space has proved difficult with other large speakers, particularly ported and transmission line designs, then it is going to trouble the Eufrodites, too.
However, if the room ratios are more benign, then teamed with quality SET amplification – from 2A3 to 833 – the Horning Eufrodite Ellipse PM 65 are undoubtedly capable of performing at a level of sophistication that will delight many buyers.
This has for me been a mightily frustrating review. While much of what I heard was very positive, my enjoyment of some aspects of the Horning Eufrodites’ performance was always tempered by the feeling that they are capable of more than they could achieve in my room. I can’t therefore give them 10/10. But then, dear reader, you’d never buy a component on my say-so alone, and neither would you dismiss one either, would you? Good!
If you’re in the market for a €20,000+ pair of speakers, then do get a listen to Tommy Horning’s Eufrodite Ellipse PM 65. You may find that in your listening space, with your equipment, that you simply can’t contemplate life without them.

Horning Eufrodite Ellipse PM65 Lautsprecher
Nachdem ich ein in Großbritannien entworfenes und hergestelltes Paar Hornlautsprecher zum Thema meiner ersten Rezension für Dagogo gemacht hatte, besuchte ich anschließend die UK National Audio Show in der Whittlebury Hall, direkt oberhalb der britischen Grand-Prix-Strecke von Silverstone.
Neugierig, andere europäische Hersteller zu entdecken, die einen hornbasierten Ansatz verfolgen, besuchte ich den Raum von LW Audio auf der Messe, auf der der Inhaber Iain Borthwick ein Paar Horning Eufrodite Ellipse PM 65-Lautsprecher vorführte. Die dänischen Lautsprecher wurden von chinesisch entwickelten Audio Music 833 Monoblöcken mit einer Leistung von 120 Watt pro Kanal angetrieben. Die Eufroditen klangen ziemlich gut und sahen interessant aus.
Einige Wochen später lieferte Iain mir die Horning Eufrodite Ellipse PM 65 nach Hause. Das Gesicht meiner Frau fiel, als sie sie auf dem Teppich in unserem Hörraum sah. "Oh. Die sind groß. Ich hoffe, sie bleiben nicht.“
Nun, ich denke, die Hornings sind nach den Maßstäben einiger Lautsprecher groß, aber nicht nach den Maßstäben anderer. Alles ist relativ.
Ich glaube aber, ich weiß, was sie meint. Sie hat sich an die Audio Note Es gewöhnt, die sich dezent in die Ecken des Raumes schmiegen, und obwohl Horning Eufrodite-Designer Tommy Horning seine Lautsprecher ähnlich nahe an den Ecken platzieren möchte, erwies sich dies in meinem Zimmer als unmöglich. Das Ergebnis einer solchen Platzierung war ein massiv matschiger Sound, dröhnender Bass und fast kein Top-End. Erst nachdem er die Horning Eufrodite Ellipse PM 65 etwa zwanzig Minuten lang bewegt hatte, erklärte sich Iain schließlich zufrieden mit dem Klang.
Die Eufrodites sind nicht die ersten Breitbandlautsprecher, die von meinem Hörraum gestört werden. Es ist etwas mehr als 21 Fuß lang und 12 Fuß 6 Zoll breit, aber es hat eine niedrige Decke von etwas mehr als 7 Fuß. Audio Note Es funktionieren auf verschiedenen Ebenen außergewöhnlich gut, ebenso wie Acoustic Energy Reference IIIs, um nur zwei Beispiele zu nennen. Große ProAcs, B&Ws, Vandersteens und PMCs erforderten alle mehr oder weniger eine sorgfältige Positionierung, um die leicht erregbaren Bassraumknoten so weit wie möglich herauszufiltern. Einige – vor allem die ProAc 3.8s – haben sich einfach nie niedergelassen. Allerdings klangen die Horning Eufrodites mit ihren vorderen Schallwänden 51 Zoll von der Vorderwand entfernt und vor der Hörposition gekreuzt, viel mehr zu Hause.
Dies wirft die Frage auf, ob ich die Überprüfung hätte aufgeben und die Eufrodites einfach an den britischen Distributor zurücksenden sollen, der sich so viel Mühe gegeben hatte, sie zu liefern und einzurichten. Lassen Sie mich das so beantworten. Mein Zimmer ist kein Einzelfall. Es gibt viele Audiophile, deren Hörräume wie meiner auf die eine oder andere Weise von dem abweichen, was Cardas als Goldenen Schnitt beschreibt. Im Rahmen einer insgesamt positiven Bewertung weise ich auf Leistungsaspekte hin, die den Lesern ähnliche Probleme bereiten können, wenn ihr Hörraum wie in diesem Beispiel Ähnlichkeiten mit meinem aufweist.
Geben Sie Tommy Hørning, was ihm zusteht; in gewisser Weise ist er seit über einem Jahrzehnt nichts, wenn nicht beständig. Der Horning Eufrodite Ellipse PM65 Lautsprecher wurde 2002 auf den Markt gebracht und seitdem hat er optimiert und gezupft, um das gleiche grundlegende Layout zu verfeinern; Das aktuelle Modell, das ich vorgesprochen habe, ist der MK 5.
Es ist entschuldigend, bei diesem rastlosen Streben nach Perfektion zwei Meinungen zu haben: Einerseits mögen wir die Entschlossenheit und Weigerung begrüßen, sich mit „gut genug“ zufrieden zu geben, aber andererseits sehen die Besitzer früherer Horning-Eufrodites den Wert ihrer Einkäufe untergraben durch die Einführung sukzessiver neuer Modelle, eine weniger als zustimmende Resonanz haben könnte.
Es ist auch anzumerken, dass der Eufrodite Ellipse PM65-Lautsprecher von Horning stark im Preis gestiegen ist – ein gewaltiger Unterschied von etwa 8.000 US-Dollar trennt den Mk IV und das aktuelle Modell, das nur wenige Jahre auseinander liegt. Tommy Hørning würde sicherlich widersprechen – und auch mit einiger Berechtigung – dass die Ellipse PM 65 erheblich teurer in der Herstellung ist als die früheren Versionen von Eufrodite. Es verwendet nicht nur einen größeren und teureren Lowther-Treiber, das Gehäuse ist auch komplexer und damit auch teurer in der Herstellung. Schließlich muss in die UVP eine Reflexion der nach Meinung des Designers gemessenen Klangleistung im Vergleich zu Alternativen zu einem ähnlichen Preis einfließen.
Die Horning Eufrodite Ellipse PM65 ist 48 Zoll hoch, 13 Zoll an der breitesten Stelle und 23 Zoll tief insgesamt. Von oben betrachtet sind die Seiten der Schränke elliptisch und verjüngen sich an der vorderen Schallwand und auch an der Rückseite auf nur 9 Zoll. Sie werden in Ply und MDF mit Innenaussteifung ausgeführt. Jeder wiegt etwa 140 Pfund, also sind es keine trivialen Dinge, die man auspacken und bewegen kann. Sie werden mit gummiähnlichen Verbundfüßen geliefert, aber Tommy Horning hat sich damit abgefunden, dass Käufer in anderen Ländern als Dänemark wahrscheinlich Spikes oder andere Stützen bevorzugen werden. Die vordere Schallwand hat ein abnehmbares Stoffgitter von oben bis unten, das nur 7 Zoll breit ist. In Kombination mit dem sehr attraktiven Apfelholzfurnier, mit dem mein Testpaar geliefert wurde, tragen die schmale Frontblende und der noch schmalere Kühlergrill wirklich dazu bei, die visuelle Wirkung der Eufrodites zu minimieren. Obwohl sie, wenn sie nach vorne positioniert waren, in meinem Hörraum nützliche Stellfläche beanspruchten, hatte ich nicht das Gefühl, dass sie eine überwältigende Präsenz hatten.
Der von Tommy Horning für die Ellipse PM 65 gewählte Hochtöner ist ein leichtes, spinnenloses Design, das mit einem größeren Magneten modifiziert wurde, um eine Effizienz von bis zu 99 dB zu erreichen. „Er geht über 20 KHz und ist meiner Meinung nach weitaus besser als jeder Ringradiator oder Kalottenhochtöner“, sagt er.
Der Mitteltöner ist ein Lowther PM 65, und nein, Sie werden ihn nicht auf der Produktliste von Lowther finden. Es ist ein 6,5-Zoll-Treiber mit einem 2,45 Tesla Alnico-Magneten und einer dynamischen Masse von nur 5,5 Gramm. Standard-6,5-Zoll-Treiber sind für den Betrieb über einen Bereich von 30 Hz bis 22 KHz ausgelegt, aber Horning entfernt den Whizzer-Kegel aus der Mitte des Treibers und klebt an seiner Stelle eine Staubschutzkappe aus Stoff, was zu einer Einheit führt, die bei etwa akustisch abrollt 6 dB pro Oktave unter 200 Hz und wird mit einem einzigen Jensen-Kondensator an einem Übergangspunkt von 12 KHz in den Hochtöner integriert.
Schauen Sie sich die Rückseite des Horning Eufrodite Ellipse PM 65 an und Sie werden die massiven Gusskörbe und Magneten von vier Beyma 8-Zoll-Tieftönern sehen, die vertikal in unmittelbarer Nähe zueinander angeordnet sind und gegen Einlasslöcher an der Rückseite der Gehäuse gezogen werden ein Käfig mit Stahlschrauben gespannt. Nicht sichtbar sind vier weitere identische Treiber in den Gehäusen, die so angeordnet sind, dass sich die insgesamt acht Einheiten über die Leere eines Viertelwellenhorns hinweg gegenüberstehen. Die beiden Bänke von Tieftönern feuern im Gegentakt, 180 Grad phasenverschoben.
Das Horn ist etwas mehr als 2,40 m lang und seine rechteckige Öffnung befindet sich knapp über dem Boden an der Rückseite der Schränke. Durch zusätzliche Kompression an seinem blinden Ende wird es akustisch um 10 % verlängert. Das Horn belastet die Beyma-Treiber, aber auch den hinteren Ausgang des Lowther PM65. Was der Hörer hört, ist daher die Summe der Direktstrahlung von Hochtöner und Lowther, integriert mit der horngeladenen hinteren Komponente des Lowthers und den Push-Pull-Tieftönern. All diese Komplexität; aber nur ein einzelner Kondensator für eine Frequenzweiche. „Der Rest der Integration erfolgt akustisch“, bestätigt Horning.
Was ihn zu dieser Komplexität treibt, ist sein Wunsch, eine hornähnliche Geschwindigkeit über den gesamten Bereich zu erreichen, ohne die großen Nachteile reiner Hörner – vor allem die Größe, die für eine überzeugende Low-End-Leistung erforderlich ist. Alles mit Hörnern, als Purist, und am Ende bekommt man für den Bass ein langes Horn, wie viele Meter lang, und das wiederum bedeutet ein Kabinett, das ungefähr so wohnzimmerfreundlich ist wie ein junger Elefant. Und da wir von Stereo sprechen – machen Sie das zwei juvenile Elefanten.
Nicht wenige Lautsprecherdesigner, die der unausweichlichen Physik etwas entgegensetzen wollen, verwenden horngeladene Kompressionstreiber für die Höhen und Mitten, kombinieren sie jedoch mit konventionell portierten oder unendlichen Schallwandkonus-Treibern – 10 Zoll, 15 Zoll und manchmal noch größer – für die unteren Frequenzen. Hornings Behauptung ist, dass dies ein zum Scheitern verurteilter Kompromiss ist und schlichtweg zu unversöhnlichen Integrationsunverträglichkeiten führt.
Hornings alternativer Ansatz besteht daher darin, ein kürzeres Horn zu verwenden, aber eine große Oberfläche zu verwenden. Ein 15-Zoll-Treiber hat eine Oberfläche von ungefähr 176 Quadratzoll, aber die achtmal 8-Zoll-Treiber des Eufrodite haben eine kombinierte Oberfläche von mehr als dem Doppelten – satte 400 Quadratzoll.
Horning ordnet seine acht Tieftöner im Gegentakt so an, dass nicht nur viel Kontrolle über die Auslenkung besteht – jeder Konus bewegt sich selbst bei starker Ansteuerung nur etwa 1 mm –, sondern auch die kleineren Magnete, die im Vergleich zum großen Karbunkel auf der Rückseite eines großen Konus erforderlich sind reagieren viel besser auf Eingaben vom Leistungsverstärker. Sie weisen daher eine weit geringere Neigung zum Aufbrechen und Verzerren auf als ein einzelner, größerer Lautsprecher mit einer Membran aus dem gleichen Material.

Horning Eufrodite Ellipse PM65 hoparlör
Dagogo için yaptığım ilk incelememin konusu olan bir İngiliz tasarımı ve yapımı bir çift korna hoparlörü yaptıktan sonra, Silverstone İngiliz Grand Prix pistinin hemen yukarısındaki Whittlebury Hall'daki Birleşik Krallık Ulusal Ses Gösterisine katıldım.
Korna tabanlı bir yaklaşım benimseyen diğer Avrupalı üreticileri keşfetmeye meraklı bir şekilde, sahibi Iain Borthwick'in bir çift Horning Eufrodite Ellipse PM 65 hoparlörü gösterdiği fuarda LW Audio'nun odasını ziyaret ettim. Danimarkalı hoparlörler, Çin tarafından tasarlanan ve kanal başına 120 Watt Audio Music 833 monoblok tarafından tahrik ediliyordu. Eufroditler kulağa oldukça iyi geliyordu ve ilginç görünüyordu.
Birkaç hafta sonra Iain, Horning Eufrodite Ellipse PM 65'i evime teslim etti. Dinleme odamızdaki halının üzerine konduklarını görünce karımın yüzü düştü. "Ey. Bunlar büyük. Umarım kalmazlar."
Sanırım Horning'ler bazı konuşmacıların standartlarına göre büyük ama diğerlerinin standartlarına göre büyük değil. Her şey görecelidir.
Sanırım ne demek istediğini biliyorum. Odanın köşelerinde gizlice toplanan Sesli Nota Es'e alışıktı ve Horning Eufrodite tasarımcısı Tommy Horning, hoparlörlerini benzer şekilde köşelere yakın yerleştirmek istese de, bu benim odamda imkansızdı. Böyle bir yerleştirmenin sonucu, muazzam derecede çamurlu bir ses, gür bir bas ve neredeyse hiç üst uç değildi. Ancak Horning Eufrodite Ellipse PM 65'i yaklaşık yirmi dakika kadar hareket ettirdikten sonra Iain sonunda sesten memnun olduğunu ilan etti.
Eufrodites, dinleme alanımdan rahatsız olan ilk tam kapsamlı hoparlörler değil. Sadece 21 fit uzunluğunda ve 12' 6 ”genişliğindedir, ancak 7 fitin biraz üzerinde alçak bir tavana sahiptir. İki örnek saymak gerekirse, çeşitli seviyelerdeki Sesli Not Esler ve Acoustic Energy Reference III'ler son derece iyi çalışır. Büyük ProAc'ler, B&W'ler, Vandersteens ve PMC'lerin tümü, kolayca uyarılan bas odası düğümlerini mümkün olduğunca dışarı çevirmek için daha az veya daha fazla derecede dikkatli konumlandırma gerektirir. Bazıları - en önemlisi ProAc 3.8'ler - hiçbir zaman yerleşmedi. Bununla birlikte, ön duvardan 51 inç uzaktaki ön bölmeleri ve dinleme pozisyonunun önünden geçmek için parmakları içe dönükken, Horning Eufrodites evde çok daha fazla ses çıkardı.
Bu, incelemeyi bırakıp Eufrodites'i teslim etmek ve kurmak için çok çaba sarf eden Birleşik Krallık distribütörüne iade edip etmemem gerektiği sorusunu gündeme getiriyor. Buna şöyle cevap vereyim. Benim odam tek seferlik değil. Dinleme alanları, benimki gibi, Cardas'ın altın orana sahip olarak tanımladığı değerden şu ya da bu şekilde farklı olan birçok odyofil var. Genel bir olumlu inceleme bağlamında, bu örnekte olduğu gibi, dinleme alanları benimkiyle benzerlikler taşıyorsa, okuyucuların benzer sorunlara neden olabilecek performans yönlerine dikkat çekiyorum.
Tommy Hørning'e hakkını ver; bir şekilde, on yıldan fazla bir süredir tutarlı değilse hiçbir şey olmamıştır. Horning Eufrodite Ellipse PM65 hoparlör 2002'de piyasaya sürüldü ve o zamandan beri aynı temel düzeni rafine ederek ince ayar yapıldı ve koparıldı; Seçmelere katıldığım mevcut model MK 5'ti.
Bu huzursuz mükemmellik arayışı konusunda ikilemde kalmak mazur görülebilir: bir yanda 'yeterince iyi' ile yetinmeyi reddetme kararlılığını ve reddini alkışlayabiliriz, ancak diğer yanda daha önceki Horning Eufrodites'in sahipleri, satın alımlarının değerinin baltalandığını görerek. art arda yeni modellerin piyasaya sürülmesiyle, onaydan daha az yanıt alabilir.
Horning Eufrodite Ellipse PM65 hoparlörün fiyatının keskin bir şekilde arttığını da belirtmek gerekir - Mk IV ile birkaç yıl arayla piyasaya sürülen mevcut model arasında yaklaşık 8.000 dolarlık büyük bir fark var. Tommy Hørning, Ellipse PM 65'in yapımının Eufrodite'in önceki versiyonlarından çok daha maliyetli olduğuna kesinlikle - ve bazı gerekçelerle - karşı çıkacaktır. Sadece daha büyük ve daha pahalı bir Lowther sürücüsü kullanmakla kalmaz, kabin daha karmaşıktır ve dolayısıyla üretimi de daha pahalıdır. Son olarak, tasarımcının benzer bir fiyat noktasındaki alternatiflere kıyasla sonik performans olduğuna inandığı şeyin bir yansıması MSRP'ye dahil edilmelidir.
Horning Eufrodite Elips PM65, 48 inç yüksekliğinde, en geniş noktasında 13 inç ve toplamda 23 inç derinliğinde duruyor. Yukarıdan bakıldığında, dolapların yanları eliptiktir, ön bölmede ve arkada da sadece 9 inç'e kadar daralır. Katlı ve MDF'de içten çaprazlı olarak yapılırlar. Her biri yaklaşık 140 pound ağırlığındadır, bu yüzden kutusundan çıkarıp etrafta dolaşmak için önemsiz şeyler değildir. Kompozit kauçuk benzeri ayaklarla tedarik edilirler, ancak Tommy Horning, Danimarka dışındaki ülkelerdeki alıcıların büyük olasılıkla sivri veya diğer destekleri tercih edeceği kaçınılmazlığına istifa etti. Ön bölme, yalnızca 7 inç genişliğinde, yukarıdan aşağıya çıkarılabilir bir kumaş ızgaraya sahiptir. İnceleme çiftimin geldiği çok çekici elma ahşap kaplama ile birleştiğinde, ön bölmenin darlığı ve hatta daha dar ızgara, Eufroditlerin görsel etkisini en aza indirmeye gerçekten yardımcı oluyor. Olması gerektiği gibi öne doğru konumlandıklarında dinleme odamda yararlı bir yer işgal etseler de, ezici bir varlıkları olduğunu hissetmedim.
Ellipse PM 65 için Tommy Horning tarafından seçilen tweeter, verimliliği 99dB'ye kadar çıkarmak için daha büyük bir mıknatısla modifiye edilmiş hafif, örümceksiz bir tasarımdır. “20 KHz'in üzerine çıkıyor ve benim görüşüme göre herhangi bir halka radyatör veya kubbe tweeter'dan çok daha iyi” diyor.
Orta kademe birimi bir Lowther PM 65'tir ve hayır, onu Lowther'ın ürün listesinde bulamazsınız. 2,45 tesla alnico mıknatısa ve sadece 5,5 gramlık dinamik kütleye sahip 6,5 inçlik bir sürücüdür. Standart 6,5 inç sürücüler, 30 Hz ila 22 KHz aralığında çalışacak şekilde tasarlanmıştır, ancak Horning, sürücünün ortasındaki vızıltı konisini çıkarır ve yerine bir bez toz kapağı yapıştırır, bu da etrafta akustik olarak yuvarlanan bir ünite ile sonuçlanır. 200 Hz'nin altında oktav başına 6 dB ve 12 KHz'lik bir geçiş noktasında tek bir Jensen kapasitörü kullanılarak tweeter ile entegre edilmiştir.
Horning Eufrodite Ellipse PM 65'in arkasına baktığınızda, birbirine yakın dikey olarak yerleştirilmiş dört Beyma 8 inçlik woofer'ın önemli döküm sepetlerini ve mıknatıslarını göreceksiniz. çelik cıvatalarla gerilmiş bir kafes. Görünmeyen, dolapların içinde, toplamda sekiz ünite çeyrek dalga boynuzunun boşluğu boyunca birbirine bakacak şekilde düzenlenmiş dört özdeş sürücü daha var. İki sıra woofer, 180 derece faz dışı itme-çekme modunda ateşlenir.
Korna, dolapların arkasında zemin seviyesinin hemen üzerinde bulunan dikdörtgen ağzı ile 8 fit uzunluğundadır. Kör ucunda ek sıkıştırma kullanılarak akustik olarak %10 uzatılmıştır. Korna Beyma sürücülerini yükler ama aynı zamanda Lowther PM65'in arka çıkışını da yükler. Bu nedenle dinleyicinin duyduğu şey, Lowther'ın korna yüklü arka bileşeni ve push-pull woofer'lar ile entegre olan tweeter ve Lowther'dan gelen doğrudan radyasyonun toplamıdır. Tüm bu karmaşıklık; henüz bir geçit için sadece tek bir kapasitör. Horning, "Entegrasyonun geri kalanı akustik olarak yapıldı" diye onaylıyor.
Onu bu kadar karmaşıklığa iten şey, saf kornaların büyük dezavantajı olmadan tam aralıklı korna benzeri hız elde etme arzusudur - öncelikle ikna edici düşük kaliteli performans elde etmek için gereken boyutta. Bir pürist olarak her şeyi boynuzlarla yapın ve bas için elde ettiğiniz sonuç, metrelerce uzunluktaki uzun bir kornadır ve bu da, oturma odasına yavru bir fil kadar dost olan bir dolap anlamına gelir. Ve stereodan bahsettiğimize göre - bunu iki genç fil yapın.
Kaçınılmaz fiziği aşmak isteyen oldukça az sayıda hoparlör tasarımcısı, üst kısımlar ve orta kısımlar için boynuz yüklü sıkıştırma sürücüleri kullanır, ancak bunları, alt kısım için geleneksel olarak taşınan veya sonsuz bölmeli koni sürücüleri ile birleştirir - 10 inç, 15 inç ve bazen daha büyük - frekanslar. Horning'in iddiası, bunun başarısızlığa mahkum bir uzlaşma olduğu ve basitçe uzlaşmaz entegrasyon uyumsuzluklarına yol açtığıdır.
Horning'in alternatif yaklaşımı bu nedenle daha kısa bir korna kullanmak ancak büyük yüzey alanı kullanmaktır. 15 inçlik bir sürücünün yaklaşık 176 inç karelik bir yüzey alanı vardır, ancak Eufrodite'in sekiz çarpı sekiz inçlik sürücülerinin birleşik yüzey alanı, bunun iki katından daha fazladır - tam bir 400 inç kare.
Horning, sekiz woofer'ını itme-çekme şeklinde düzenler, böylece sadece gezinme üzerinde çok fazla kontrol olmaz - her koni sert sürüldüğünde bile yaklaşık 1 mm hareket eder - aynı zamanda büyük bir koninin arkasındaki büyük karbonkül ile karşılaştırıldığında daha küçük mıknatıslar gerekir güç amplifikatöründen gelen girişe çok daha duyarlıdır. Bu nedenle, aynı malzemeden yapılmış bir koniye sahip tek, daha büyük bir hoparlörden çok daha düşük kırılma ve bozulma eğilimi gösterirler.
