RCF MB15N351

Reproduktor 15", 650W, 100dB, 40-3000Hz, X-max 5,5mm, hmotnost 5,0kg

This MB15N351 is designed to provide an excellent linearity in the frequency response with low distortion.

The transducer is built around a very stronger neodymium magnetic structure and a new 3,5” voice coil, this combination provides to increase the power handling especially in comparison a standard 3" voice coil.

The unique Dual-forced air venting system guarantee a very efficient voice coil ventilation for minimize the power compression at the higher power handling.
