- 3.5-inch, inside/outside copper voice coil
- 1300W continuous program power handling
- 100 dB Sensitivity
- 40 Hz â 3 kHz Frequency range
- Dual-forced air ventilation for minimum power compression
- Dual spider design with silicon based dampening control
This MB15N351 is designed to provide an excellent linearity in the frequency response with low distortion. The transducer is built around a very stronger neodymium magnetic structure and a new 3,5” voice coil, this combination provides to increase the power handling especially in comparison a standard 3″ voice coil. The unique Dual-forced air venting system guarantee a very efficient voice coil ventilation for minimize the power compression at the higher power handling.
