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.

Features

• 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

Applications

• The MB15N351 is ideal for use in applications where is required a very high efficiency and linearity with high power handling.
• It's especially used for high powered multi-way system.
