215 Signature Bicone Fullrange driver – 35W / 94.5dB / 8 Ohms
The 215 Signature has been derived from the legendary 215 RTF Bicone (Dual-cone).
It is the result of years of experimenting and researching for the best balanced sound. Supravox has considerable experience in terms of cone treatment and coupling magnet/Voce coil. A new cone treatment allows for a seamless and non fatiguing junction between the main cone and the dual-cone as well as a better control of micro-fractionning of the cone…The magnet and the voice coil have been designed in order to allow for deep excursion of the cone (+/-4mm) to allow a better bass reproduction with limited dynamic compression. Bass reproduction is therefore deep but precise, nervous and taut.
This driver offers an excellent compromise between a splendid reproduction of the lower frequencies and a high sensitivity of close to 95dB/2,83V.
The resulting sound is very balanced for a full-range driver.
