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 low register loudspeaker of high efficiency (96 dB) uses the same moving element as 400-2000. Its difference is the magnet and the field plate (ferrite of 220 mm instead of Alnico ). These qualities enable him to be directly coupled with our 1 inch horn.

It can be used in a bassreflex or jensen, crossed with 500Hz, the response curve will be linear with ± 2 dB from 40 Hz until the final frequency of 1 inch driver. It can be used perfectly for low register (symmetrical load).
