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 high efficiency drive unit offer a very fast low register to you and pleasant listening. Ideal listening with an amplifier of low power (tube or transistor) of approximately 10W, it supports also stronger powers for a use out of low register boxes. In open baffle, it will reinforce, with the same degree of accuracy of reproduction the 215 rtf, to add a low register reinforcement to him and to ensure a comfortable and balanced listening.
In column TQWT it will emphasize all the smoothness of your preferred listenings.
In RJ subwoofer, bass reflex or symmetrical, it will be a low register of accompaniment of most precise. This driver unit could be coupled with an 1 inch driver + horn.
