400 GMF 98.5db high sensitivity woofer

400 GMF 98.5db high sensitivity woofer

The new high bass speaker
Performance (98.5 dB) gives you a fast, deep bass, very pleasant.

It uses the same moving parts than the 400-2000 but a different ferrite magnet of 220 Mm giving this woofer a very high magnetic field and a high efficiency.

The 400 GMF can be used with a horn and driver (one inch ok) Mounted in a bassreflex box or
jensen, cut off at 500/600Hz, the frequency
response will be straight at ± 2 dB until the cut-off frequency. 

With an extremely low FS of the order of 20Hz, it will be a great driver for building a high quality sub-woofer.
