- Diaphragm

The diaphragm of the loudspeaker is realized after a world-wide protected patent. An uncoupling mechanism separates the bass diaphragm from the more highly frequent sound portions.

The uncoupling mechanism is installed in such a way between voice coil neck and low clay/tone diaphragm that the low clay/tone diaphragm is not decoupled by the more highly frequent signal and does not radiate any more. The high clay/tone radiating range remains thereby in the ideal center of the construction and the entire transmission corresponds to the ideal single-point source.

That means, a construction had to be developed, which rests directly against the moving coil neck, that does not absorb high frequency sound parts and still transfers deep frequency parts fast enought. That seemed a nearly impossible goal. But after years of research work, persistent attempts and audio studies it could be managed perfectly. The result convinces. One of the best broadband diaphragms was developed, which actually is also able to radiate the complete frequency band.

The material of the diaphragm is a special paper mixture. Tests with exotic and high-technological diaphragm materials showed that these form usually an optimization on closer frequency bands - ideal for midrange and bass speakers ideally. For a broad-band radiating loudspeaker according to the piston principle these proved however as unsuitable.

- Voice coil

The voice coil is an unsupported coil and is made from a high-strength and extremly light sandwich-voice-coil-supporter. The voice coil wire is made from copper-clad aluminium and is wrapped rectangular in one layer in a width/height proportion of 4:1. The extreme fill factor which is reached thereby is also decisive for the exceptional pulse processing of the chassis. In addition, the voice coil thereby gets its extremely light weight and has an even slighter resistance on its surface. Likewise, the skin effect, which is only theoretical in loudspeaker frequency ranges, thus does not appear anymore.

The adhesive of the voice coil is a high-temperature resistant High-Tech construction. The technical problems, which prevent other producers from using such voice coils, have been solved by VOICE-POINT. So here, too, decisive advantages are given, which render such a fantastic chassis possible.

- Magnet

With more than three kilograms the magnet is extremly dimensioned and has the most narrow air gap known to us which has ever been used in broad band speakers in the whole history of loudspeakers.

The air gap is so narrow that the insulating lacquering of the voice coil has to be polished, in order to level possible unevenness. It measures only the 50-thousandth part of a milimeter. Thus an optimal utilization of the magnetic gap energy is guaranteed.

The measurements and the size of the magnet are chosen not only for its strenth. As there is no need for a reduction of weight in studio- or home-speakers, VOICE-POINT took advantage of the greater mass and surface for an optimal cooling of the voice coil and magnetic gap.
