Haut-parleur sono 46cm FANE Colossus 18B600
[COL 18B-600-8] Avis/Critiques The Colossus 18B-600 is intended for use 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. This, coupled with a large Xmax of 7.2 mm, ensures tight, punchy bass at high levels of excursion. 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 extreme sound pressure 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 18B-600 exhibits 98 dB sensitivity and can deliver bass down to 32 Hz (-6 dB) in a 200 litre ported enclosure.
