IL PREZZO SI RIFERISCE AL SINGOLO WOOFER.

 

The LF18N405 is an extended low frequency with high power handling , designed to provide powerful and accurate bass frequencies with low distortion, low power compression and very high SPL.

The LF18N405 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control.

The single spider system is specifically designed with a heavy cloth which ensures excellent control during large excursions. A fully optimised T-pole design generates the minimum amount of flux modulation.

The Dual-forced air venting magnetic structure system provides a very efficient voice coil ventilation to minimize the power compression.
