RCF MB12N301 8/ohm

Podrobný popis

Reproduktor 12", 500W, 98,5dB, 50-3000Hz, X-max 6mm, hmotnost 3,4kg

The MB12N301 is a neodymium, high efficiency, 12” 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.
