RCF MB15N351 - 15" 650W 8 Ohm
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.
Applications:
The MB15N351 is ideal for use in applications where is required a very high efficiency and linearity with high power handling.
Its especially used for high powered multi-way system.
Main 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
