Product Sheet

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.

 

 

A high low register speaker of audiophile quality: the 400 EXC offers very high quality of answer (speed and broad band) because it is built goshawks of the same membrane as 400-2000. Its advantage remains open the possibility of adjustment of these parameters thanks to a powerful engine electromagnetic. Adaptable of this fact to many enclosures, it requires an external power (ideal of 10 with 14V for 5A).
