RCF MB15N351 Mid-Bass

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.
