Product Sheet

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.


This driver unit, creates in 2001, is bafflable in small volume, in bass reflex or TQWT it can occur from low register box for a fast and powerful reproduction of the low frequencies until 50 Hz.

Plans are available on the site. It can also be used in full range medium in enclosures 3 ways of quality.
