Haut-parleur sono 38cm FANE Colossus 15B600
[COL 15B-600-8] Avis/Critiques The Colossus 15B-600 is intended for use in high-power two-way ported enclosures and as a high-output bass driver in multiway systems. It features a 4-inch voice coil immersed in a symmetric magnetic field yielding increased linearity and lower distortion at high excursion levels. 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 driver handles 600 Watts (A.E.S) continuous and can cope with peaks in excess of 2400 Watts. This is due to advanced thermal management in the form of vented die-cast chassis and motor system coupled to a large vaned heatsink mounted on the rear of the unit. These measures effectively remove heat from the voice coil, resulting in extremely low-power compression.
The Colossus 15B-600 exhibits an average sensitivity of 99 dB and can deliver bass down to 40 Hz (-6 dB) in a 125 litre ported enclosure.
