The Colossus 18XLS features a 4-inch, inside / outside windings, copper voice coil and is intended for use as a high output bass driver in multi way systems. The coil is immersed in a symmetric magnetic field that yields increased linearity and lower distortion. This, coupled with laminated silicone suspensions, a large Xmax of 12.5 mm with peak to peak travel of 60 mm, ensures fast accurate 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. Thanks to advanced thermal management the vented die-cast chassis and increased motor system venting effectively remove heat from the voice coil, resulting in extremely low-power compression. The driver handles 1200 Watts (A.E.S.) continuous coping with peaks in excess of 4800 Watts, exhibiting 97 dB sensitivity over its working band.
- Please enquire about alternative impedances.
- A.E.S. power handling test. Pink noise bandpass filtered at 12 dB per octave with cutoff frequencies of 30 Hz and 300 Hz. Driver mounted in free air, test signal applied at rated power for two hours.
- Please note that the frequency response measurements are supplied for comparison only and are not a measure of the low frequency performance which may be achieved in a fully optimised system.
