Description
RCF MB15X351 15" Power: 700W rms, 1400W prog. Sensitivity: 99 dB Freq. Range 46-2500 Hz
The MB15N351 is designed to provide an excellent frequency response linearity with very low distortion. A very strong neodymium magnetic structure guarantee dynamic and precision, a new and unique 3,5” voice coil design provides a very high power handling, especially recommended in comparison to a standard 3” voice coil. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling.
