RCF MB12X351 - 12" 700W 8 Ohm
The MB12X351 is designed to provide an excellent frequency response linearity with very low distortion.
A very strong ferrite magnetic structure guarantee dynamic and precision, a new and unique 3.5" voice coil design provides 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. The MB12N351 is ideal for use in applications where very high efficiency and linearity are required in conjunction with high power handling.It is especially recommended for high powered two-way or multi-way systems.
