L18P300ND

WOOFER

The L18P300ND is derived from L18P300 but with a neo magnetic design and manufactured with a newly designed aluminum basket that provides an excellent ventilation of voice coil,this solution is perfectly compatible with the ferrite version for size and performance.
The neo magnetic assembly use a 15mm thickness plates that ensure a high flux density in the gap, low power compression and excellent haet dissipation.
A specially designed of M-roll suspensions that combined with a double silicon spider ensure an excellent linear piston control and an undistorted low frequency reproduction at very high power.
