To get into the technical aspects of the 6371’s I contacted the legendary Joe D’Appolito, Usher’s design consultant: “The design goals for the CP6371 were flat on-axis response and broad uniform horizontal polar response. The first goal yields accurate first arrival information critical to imaging. The second goal assures a balanced reverberant field and broadens the sweet spot. This is required because we judge overall frequency balance psycho-acoustically by fusing (i.e., integrating) direct and reflected arrivals over a period of 5-30 milliseconds (the Haas fusion zone). To this end, the CP6371 is a two and one-half way (2.5-way) system. The lower woofer crosses out at 350Hz to prevent combing response errors in the vertical plane. It doubles the low-bass output and compensates for the spreading loss. The overall woofer pair/tweeter crossover is an acoustic 4th-order in-phase linkwitz alignment at 2450Hz The crossover uses heavy gauge air core coils and quality film capacitors mounted on glass fiber reinforced printed circuit boards. All the drivers used in the CP6371 (and all the Series 6 speakers) have been designed by Mr. Tsai and are manufactured in-house by Usher. Here are some details on the drivers: Two 8945A woofers are used in the CP6371. The 8945A woofer is a very sophisticated low-distortion woofer. It comprises a cast aluminum frame and a carbon fiber filled paper cone, a T-shaped pole piece with copper shorting ring and copper sleeve Low-loss linear suspension with a large flat spider and large half-roll surround. The sophisticated motor yields very low distortion at high SPLs. The T9950 is a very low-distortion tweeter with a 28mm coated silk dome, an aluminum voice coil former, optimized pole piece geometry, large rear chamber for low resonance and light ferro-fluid damping. Internal wiring is four 9s OFC and the connectors are by Faston.Specifications: 2 Way system: tweeter 1” (9950-20), midbass (2) 7” (8945A) Sensitivity: 90dB @ 1 watt/1 meter Nominal Impedance: 4 ohms Frequency Response (-3dB): 30Hz ~ 28kHz Power Handling: 120 watts Crossover FrequencY: 2.7Hz Weight: 52.5kgs (including base) Dimensions (w x d x h): 14” x 25.5” x 50”)
