Reproduktor 12", 500W, 97,5dB, 40-2500Hz, X-max 6,8mm, hmotnost 3,4kg

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
