Voxativ Fullrange Driver AC-4X
Voxativ builds all full-range drivers by themselves. Only the highest quality materials are used, and all assembly and calibration is done manually in Germany. Voxatives subjects all drivers to a 24-hour endurance test and inspect them again very thoroughly before they are dispatched. This ensures that you receive a premium product built to the very highest precision. It results in a sound which is a delight to experience, even for those with little interest in hifi.
The world premiere of these drive units appeared in 2013 - The fullrange drive unit AC-4x is equipped with a cone made of real wood.
Although the new cone has the same moving mass as the predecessor of Japanese calligraphy paper, it's stiffness is 100 times higher.
The use of a more powerful magnet system also leads to considerable sound improvement.
The audio impression is breathtaking: a much stronger bass response and in mids and highs there are more clarity and details.
The result is nothing less than the best full range unit of the world !
Starting in January 2013 the Ampeggio Signature is be equipped with the new drive unit AC-4x. Obviously, this cone is also available for our AC-Xp driver in the Ampeggio Due. Retrofit to other drivers on request.
Price is for a pair.
