A product of years of intensive research and development. It's the fusion of decades of experience with state-of-the-art technology. The challenge was to create an entirely new dimension of sound. The unique bionic surface structure overcomes issues of sound propagation, resulting in a natural sound image. Countless hours of dedication were invested to develop a special embossing that allows for direct axial sound radiation. The proven 3-layer sandwich construction remains intact, with every detail meticulously refined. The result is not just a product but a musical experience at the highest level that will captivate every music lover. 

ZELLATON ULTRA Diaphragm

After many years of research and development work, we have combined decades of experience with state-of-the-art technology in our new ZELLATON ULTRA diaphragm.

The result is a ULTRA high-tech diaphragm that combines all the positive properties of different materials. To achieve this goal while retaining all the advantages of the previous ZELLATON KLASSIK diaphragm, a completely new concept was necessary!

The surface structure of the ZELLATON ULTRA diaphragm reflects the principle of bionics, i.e. the use of surface structures in nature to achieve optimal solutions.

The novel and unique surface structure of the ZELLATON ULTRA diaphragm effectively prevents sound propagation at the diaphragm surface and at the same time significantly increases the stiffness of the diaphragm.

Another major difference from most diaphragms on the market is that the special embossing allows the sound to be radiated directly in the axial direction, resulting in an incredibly natural sound image.

Of course, the proven 3-layer sandwich construction has been retained to maintain the well-known benefits of sandwich construction. A modern, shock-absorbing high-tech foam with maximum breaking strength is used, with a specially coated, artisanal handmade paper on the back.

The result is an extremely stiff and low partial vibration full-cone with the highest internal damping. The partial vibrations of each mid-range cone, which are still present after assembly, are specifically damped in an elaborate manual process.

Highly customizable to meet any taste
