Fane Colossus 12BM - 12" 450W 8 Ohm
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 `sandwich' inside- and outside-wound 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 98 dB and is best used in ported enclosures of 25 to 80 litres.
- Available for BULK ORDER / OEM only.
- Non-inductive motor system reduces distortion.
- Fast dynamic response combined with superior suspension material.
- High BL, 21 T/m.
- UK manufactured cone with optimised pulp offering increased strength, durability and performance.
