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.
Evolution of the 285 GMF, this loudspeaker offers qualities of reproduction close to the version ferrite (GMF) because they have the same moving element.
On the other hand the oversize engine of excitation makes it possible the 285 to pass the barrier of 100dB SPL. Its magnetic field is adjustable and adaptable of this fact to many enclosures, it requires an external power supply (ideal of 6 to 12V for 5A).
