COLOSSUS 15SB

The Colossus 15SB is intended for use in two-way ported enclosures or as an high output bass driver in multi-way systems. The unit features a 4 inch 'sandwich' inside and outside windings voice coil driven by a non-inductive motor system which dramatically reduces third-harmonic and intermodulation distortion. The cone membrane is state of the art material that allows the driver to combine high sensitivity with the structural integrity required to produce undistorted frequencies at high output levels. The mechanical and electrical properties of the unit have been carefully optimised to allow extended low frequency output up to its rated power handling of 800 Watts (A.E.S) continuous, with peak power handling in excess of 3200 Watts. The driver exhibits an average sensitivity of 99 dB working band and is best used in ported enclosures of 45 to 125 Litres. The Colossus 15SB can deliver bass down to 40 Hz (-3dB), 30 Hz (-6dB) in a tuned 125 Litre ported enclosure.

• Please enquire about alternative impedances.
• A.E.S. power handling test. Pink noise bandpass filtered at 12 dB per octave with cutoff frequencies of 45 Hz and 450Hz. 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.
