Classic series
Its objective, to maintain the philosophy of SUPRAVOX, full range driver units and high efficiency. We work still to widen the useful bandwidth for a highest efficiency possible, while unceasingly improving the definition, the quality and the linearity. Diameter 135 to 380 mm, the audiophile can satisfy its passion.

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.
