RCF MB15X351 - 15" 700W 8 Ohm
The MB15X351 is designed to provide an excellent frequency response linearity with very low distortion.
A very strong ferrite magnetic structure guarantee dynamic and precise performance, a new and unique 3.5" voice coil design provides a very high power handling, especially recommended in comparison to a standard 3" voice coil. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling.
