RCF MB15N301 15-inch NEO Mid Bass Sub Woofer 500 WMS 1000 Watts Peak 3-Inch Fibreglass Voice Coil Precision Transducers Pro Audio Speaker 8-Ohm

The MB15N301 is a neodymium, high efficiency, 15” 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 aluminum 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, fiberglass inside/outside copper voice coil || 1000 Watt continuous program power handling || 99 dB Sensitivity || 40Hz –3.5KHz Frequency range || Dual-forced air ventilation for minimum power compression || Triple-roll surround and exponential cone geometry || SPECIFICATIONS || Nominal Diameter : 15 inch / 381 mm || Rated Impedance : 8 ohm || Program Power (watt) : 1000 W || Power handling capacity : 500 W || Sensitivity : 99.0 dB || Frequency range : 40 - 3500 Hz || Effective piston diameter : 330 mm / 12.99 inch || Max.
