IL PREZZO SI RIFERISCE AL SINGOLO WOOFER.

 

The LF21N401 is a high power handling and efficiency transducer specially designed to provide powerful and accurate sub-bass frequencies with low distortion and low power compression.

With a fast time response, the LF21N451 uses a fiber loaded cone assembly along a large triple roll surround. This combination provides emarkable strength and control.

Double silicon spider system ensures excellent control during large excursions. A fully optimized T-pole design generate the minimum amount of flux modulation.

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