RCF CX12N351

Top class coaxial design that provides an excellent frequency response linearity with very low distortion

12"/1.4” Leistung: 450W/900W + 90W/180W RMS/Prog.) Schalldruck SPL 1W/1m (Woofer/Driver): 98,5/110dB Freq. Range 50-20.000 Hz HF 60° Radial-Horn, coaxial

The CX12N351 is powered from an integrated high power neodymium magnetic structure that guarantee high dynamic and sensitivity for both components.
The mid-bass section features a 3,5" inside-outside voice coil design that provides a very high power handling, especially in comparison to a standard 3" voice coil.
Thanks to an integrated demodulation ring the mid-bass section gets a fastest time response and lower distortion.
The compression driver use a 2.5" diaphragm with a 1.4" throat featuring several state of the art technologies.
The diaphragm and suspension are formed from 0.05 mm thick pure titanium.
