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.

 

The 215 Signature is an evolution of the 215 rtf. It is the result of the Supravox experiment on the treatments of cone and the optimization of the couple magnet/voice coil. The engine and the voice coil were modified for a better reproduction of the low registers without compression of dynamics. The linear excursion passes from +/- 2mm (versions rtf) with +/- 4mm.

It offers a low register deeper tended and precise. All this is paid by a sensitivity of 94dB/W. This 215 is has to privilege for the followers of a very balanced listening. Without the bicone the answer is linear up to 10 Khz.
