The Ceramic Alu Cone (CAC) is an in-house development by Magnat that ensures significantly improved reproduction – and in multiple areas. In terms of structure, it is a so-called "sandwich membrane". A core layer made of aluminium is enclosed by ceramic material on both sides. A complex chemical process produces a composite material that offers high internal damping and, at the same time, avoids sound-distorting partial vibrations. The cone membrane takes advantage of the combined properties of ceramic (strength) and aluminium (flexibility and low weight) to guarantee high-precision reproduction of every audio signal. The result: outstanding, authentic sound.
