The Hyper-Holographic Cone Tweeter

Brand-new: The first ever tweeter without any typical “Tweeter-own-sounding”, short: the first tweeter that you “can`t hear”!

Back to the Future

Cone tweeters, notorious for being used in cheap loudspeakers picked off the supermarket shelves, went out of fashion years ago. New light weight, soft materials were implemented to reduce the overall moving mass, however these materials also required a new geometry to ensure stiffness and stability: The dome. With the introduction of new, stiff and yet lightweight material, the use of dome-shaped tweeters is becoming more and more questionable. Soft domes tend to wear out at an early stage where the movement at the rim is different from the movement occurring in the interior zone.  As a result, the dome starts “to ring” where it adds its own audible colorations to the signal.  Instead of hearing the music, you hear the sonic signature of a ringing tweeter. Light, stiff membrane material does not need to struggle with the trade-offs involved in using domes – therefore, in the case of midrange drivers, the use of domes has practically dissolved into thin air over the past couple of years.

Audio Physic took the next logical step by further exploring the subject of cone membranes in tweeter systems. Already the first cones put to the test were highly acclaimed by a critical audience. Here, high frequencies came through uninhibited by the loudspeaker and were reproduced with holographic quality displaying an unparalleled degree of plasticity in two channel sound reproduction such as Q Sound. After a series of handcrafted prototypes fitted with stiff, ceramic-coated metal diaphragms, a revolutionary tweeter has been optimised for production.

The hyper-holographic cone tweeter has an extremely lightweight, yet surprisingly unyielding and stiff aluminium diaphragm, coated with ceramic, where a small soft dome is covering the interior zone. The suspension is applied to the rim. Nothing prevents the sound from travelling out of the voice coil, reinforced by fibre glass, to the diaphragm. The tweeter is driven by a magnet system arranged of four  Neodymium plates ensuring a particular high performance and efficiency. As a result, the cone tweeter is capable to reproduce a holographic sound field where the sound appears seemingly from out of nowhere and not associated with conventional tweeter behaviour – where sometimes the special coloration  can be interesting in the first place.

It may have been a long way to go for a tweeter design sophisticated enough to not add its own coloration to the sound, but it was worth every mile of it: At Audio Physic we are pleased and proud to say that our revolutionary hyper-holographic cone lets the music through with virtually no discernible imprint of its own. We have designed a cone able to play the music just the way the sound engineer wanted it to sound.
