GMF Bass medium drive unit. |
|
 |
A bass medim driver with very great dynamic qualities. This driver unit remains easily baflable in Jensen boxes or rather bass-reflex volume. With its 97 dB/W at 1m of efficiency the bet of the very high efficiency is reached and this with a linear excursion without compression of dynamics (+/- 5mm). The admissible power is the highest of all the 215 Supravox.
