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.
• 3.5-inch, inside/outside copper voice coil
• 1300W continuous program power handling
• 100 dB Sensitivity
• 40 Hz 3 kHz Frequency range
• Dual-forced air ventilation for minimum power compression
• Dual spider design with silicon based dampening control
