The LF12N301 is a high power 12” neodymium woofer with excellent sensitivity and excursion 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.
Features 3.0-inch fiberglass inside/outside copper voice coil 1000 Watt continuous program power handling 97.5 dB Sensitivity 40 Hz - 2.5 kHz Frequency range Dual-forced air ventilation for minimum power compression M-roll surround and exponential cone geometry
