Description
RCF MB15N301 15" Power: 500W rms, 1000W prog. Sensitivity: 99,5 dB Freq. Range 40-3500 Hz
The MB15N301 is a neodymium, high efficiency, 15” mid-bass. High sensitivity, excellent linearity and very high power handling capabilities. The magnetic structure is powered by a large neodymium magnet that provides an extremely high flux density in the gap. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. M-roll surround and spider design offer great linearity and precise reproduction.
