  • Lightweight neodymium magnet assembly.
  • Weighs only 4.2 kg.
  • Fast dynamic response combined with superior suspension material.
  • Suited for line array applications.
  • Non inductive motor system reduces distortion.
  • High BL, 20 T/m.
  • UK manufactured cone with optimised pulp offering increased strength, durability and performance.

The Colossus 12BMN is intended for use as a very high-output mid bass driver in two-way ported enclosures and also as a bass driver in multi way systems. The unit features a 3 inch voice coil driven by a non-inductive motor system which dramatically reduces third-harmonic and intermodulation distortion. The cone membrane, manufactured from bespoke paper pulp 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 low frequency output up to its rated power handling of 450 Watts (A.E.S) continuous, with peak power handling in excess of 1800 Watts. The driver exhibits an average sensitivity of 99 dB and is best used in ported enclosures of 25 to 80 Litres.


  • Please enquire about alternative impedances.
  • A.E.S. power handling test. Pink noise bandpass filtered at 12 dB per octave with cutoff frequencies of 50 Hz and 500 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.
