215 EXC Full range drive unit
20W / 90 at 99dB / 4 Ohms
A moving element and an answer identical to the 215-2000 alnico. Its advantage is the possibility of adjustment of these parameters thanks to a powerful electromagnetic engine. Adaptable of this fact to many enclosures, it requires an external power supply (ideal of 10 to 14V for 5A).
Description
EXC Series
Its objective, to maintain the philosophy of SUPRAVOX, full range drive units and high efficiency. With EXC series (driver unit with excitation), diameter 165 to 380 mm, the audiophile can satisfy its passion. The Supravox team, always in intense activity of research, proposes four evolutions of these traditional references equipped with a powerful electro magnet.
