RCF CX15N351

Koaxiální reproduktor 15"/1,4", 650/90W, 101/110dB, 40-20000Hz, X-max 5,5mm, vyzař.úhel 60°, hmotnost 6,5kg



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.
