RCF MB12N301 500W AES 12" 4 Ohm Replacement LF driver for ART422A

The MB12N301 is a neodymium, high efficiency, 12' mid-bass. High sensitivity, excellent linearity and very high power handling capabilities. The magnetic structure is powered by a large neodymium magnet that provides an extremely high flux density in the gap. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. M-roll surround and spider design offer great linearity and precise reproduction.

Applications:

The very light moving mass and linear curve response make the MB12N301 the solution for high quality two or three way system.
The aluminium voice coil guarantee a very high efficiency in conjunction to a proper Q factor for good bass response.

Main Features:

3.0-inch, fibreglass inside/outside copper voice coil
1000 Watt continuous program power handling
98.5dB Sensitivity
50Hz -3.0KHz Frequency range
Dual-forced air ventilation for minimum power compression
M-roll surround and exponential cone geometry
