This 12 inch Coaxials is designed to provide an excellent frequency response linearity with very low distortion. This coaxial use a strongest unique neodymium magnetic structure that guarantee high dynamic and sensitivity for both components. The mid-bass section use a 3.0 inch voice coil design provides a very high power handling, demodulation ring get a fastest time response and lower distortion.
The compression driver use a 4 inch diaphragm with a 1.3 inch throat featuring several state of the art technologies. The diaphragm and suspension are formed from Polyimide+ 0.05mm thick pure titanium. The unique magnetic structure allow to get a single point source that providing coherent wave front.
