12" Transducer with an excellent frequency response linearity and very low distortion
The MB12N351 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 unique Dual-forced air venting system guarantee a very efficient voice coil ventilation to minimize the power compression and provide higher power handling.
