The woofers: carbon
Woofer cones from Danish Audio Technology are made from two thin carbon reinforced paper cones, which are glued together with an expanding foam, using a support tool, to keep the cone in the correct shape. The foam is well damped to avoid resonances in the cone. The result is an extremely rigid and stiff cone, presenting fast, uncolored and distortion free bass. The voice coil is made from a mixture of kapton and aluminum. This means, the driver acts as a pure kapton voice coil driver, as long as the voice coil is within its linear working area. It also presents a very low mechanical resistance, which allows the driver to play bass with authority, even at low levels. All drivers are naturally generously ventilated, under the spider, from voice coil gap and not least through the pole piece, allowing the whole moving system to travel fast and freely, without any compression.
