CX15N351 Coaxial
This CX15N351 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 3,5” voice coil design provides a very high power handling, especially recommended in comparison to a standard 3" voice coil, demodulation ring get a fastest time response and lower distortion . The compression driver use a 2.5-inch diaphragm with a 1.4 inch throat featuring several state of the art technologies. The diaphragm and suspension are formed from 0.05mm thick pure titanium. The unique magnetic structure allow to get a single point source that providing coherent wave front.
