Haut-parleur sono 30cm FANE Colossus 12MB
[COL 12MB-8] Avis/Critiques The Colossus 12MB is intended for use as a very high-output bass mid driver in two-way ported enclosures and also as a bass driver in multiway systems. The unit features a 3-inch voice coil driven by a noninductive motor system which dramatically reduces third-harmonic and intermodulation distortion. The cone membrane, manufactured from Polycellulose, is much stronger and more durable than conventional paper pulp alternatives. This allows the driver to combine high-sensitivity with the structural integrity required to produce undistorted low frequencies at high output levels. The mechanical and electrical properties of the unit have been carefully optimised to allow extended lowfrequency output up to its rated power handling of 450 Watts (A.E.S continuous).
Heat is dissipated from the ultralight aluminium voice coil by a composite glass fibre and black anodised aluminium former. This assists in yielding outstanding power handling from a 3-inch coil, with peak power handling in excess of 1800 Watts. The driver exhibits an average sensitivity of 98 dB and is best used in ported enclosures of 25 to 80 litres.
