Features

3-inch, fibreglass inside/outside copper voice coil
1000W continuous program power handling
98.0 dB Sensitivity
45 Hz – 2.5 kHz Frequency range
Dual Forced Hyperventing System
M-roll surround and exponential cone geometry

The MB12X301 is designed to provide an excellent frequency response linearity with very low distortion. A strong magnetic structure guarantee dynamic and precision. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling. M-roll surround, exponential cone geometry and spider design offer great linearity and precise reproduction.
