LF12N301

WOOFER

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.

Applications
  • • The excellent linear response, well controlled down to 50 Hertz, makes the LF12N301 especially suitable for small size bass reflex systems and band-pass subwoofers.
  • • It is a very good solution for two or three way system when a good BL and punch are required.
