RCF CX15N351 - 15" 450W 8 Ohm
The CX15N351 is designed to provide an excellent frequency response linearity with very low distortion.
This coaxial uses a unique high-powered neodymium magnetic structure that guarantees high dynamic and sensitivity for both components. The mid-bass section use a 3.5" voice coil design provides 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 allows a single point source that provides an exceptionally coherent wave front.
