RCF MB12N301 12" Neodymium Mid-Bass Excellent Linearity & Very High Power 1000W

Description

RCF MB12N301 12" Neodymium Mid-Bass High Efficiency, High Sensitivity, Excellent Linearity & Very High Power Handling Capabilities
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.
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
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.
