The MB12X351 is designed to provide an excellent frequency response linearity with very low distortion. A very strong neodymium magnetic structure guarantee dynamic and precision, 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.
Features 3.5-inch, fiberglass inside/outside copper voice coil 1400W continuous program power handling 98.5 dB Sensitivity 45 Hz - 2.5 kHz Frequency range Dual Forced Hyperventing System Dual spider design with silicon based dampening control
