Description

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 full range driver unit and high efficiency is not other than evolution 95 of the HP of legend which equipped the studios of the house of the radio, the ORTF, of the RAI, RTL and EUROPE 1. Approved opera, it gets a cordial listening with the clear and precise medium and offers multiple possibilities of assembly. Ideal listening with an amplifier (tube or transistor) of low power of approximately 10W.

In open baffle, the spacial presence of the sound will enchant you, the HP expresses its great dynamics as well as possible. In TQWT it will emphasize all the smoothness of your preferred listenings. This HP can be reinforced by a tweeter of the type JBL 2405 or B&C D-32 with a simple cut with 10kHz by one wrapped of 0.47 or 0.33 uF. The low register can be reinforced, in particular in open baffle by the 285 or the 400 SUPRAVOX cut at 100Hz.
