From PRV Audio's Forte Series, the 6MB550FT 6-1/2" midbass is capable of powerful output while producing low distortion. With 5.4 mm xmax and 275 watt RMS power handling, this driver will produce midbass with output you can feel. The cone is driven by a large 2" voice coil with ample venting to handle continuous high power while dissipating enough heat to keep power compression at a minimum. Holding everything together is a rigid cast aluminum frame that is designed to handle the use and abuse of the pro sound environment. With smooth response from 85 to 7,500 Hz, the 6MB550FT is a great choice for subwoofer assisted 2-way designs and large high output 3-way systems.
