Data Sheet
(0 Reviews)  Review this item
  • 1000 W Program Power.
  • 98.5 dB Sensitivity (1W/1m).
  • Weighs only 4.3Kg thanks to a lightweight neodymium magnet motor assembly.
  • Optimised non-inductive motor system efficiently controls magnetic flux and reduces third-harmonic and intermodulation distortion.
  • Excels when deployed in line array applications for fast, dynamic and punchy bass.
  • Extended frequency range working up to 4 kHz.
  • Aluminium demodulation and copper shorting Rings.
  • UK manufactured cone with optimised pulp offering increased strength, durability and performance.
  • Intended as a high-output mid-bass driver in two-way ported enclosures of 25-80 Litres.
  • Also performs well as a bass driver in multi-way systems.
  • 3-inch Inside/ outside windings aluminium voice coil.

The Colossus 12MBN is intended for use as a very high-output bass mid driver in two-way ported enclosures and also as a bass driver in multi way systems. The unit features a 3 inch 'sandwich' inside and outside windings voice coil driven by a Neodymium non inductive motor system which dramatically reduces third-harmonic and intermodulation distortion. 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 mechanical and electrical properties of the unit have been carefully optimised to allow extended low frequency output up to its rated power handling of 500 Watts (A.E.S) continuous, with peak power handling in excess of 2000 Watts. The driver exhibits an average sensitivity of 98.5 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.
