BGW M2200 & M1100

Demands for high level sub-bass place enormous requirements on separate system components. Typical subwoofer systems display mismatched load impedances, wasted power in cabling, and inadequate protection schemes, often resulting in failure of drivers. BGW recognized the need for a complete systems solution. The results are BGW's M2200 and M1100, simply twice as effective as any other commercially available sub-bass solution. BGW "plug 'n play" subwoofer systems seemlessly integrate into any existing installation, to create an awesome musical experience.

Conservative Design
BGW Engineers started with our largest Grand Touring Amplifier, the GTA. This 78 pound monster is an ideal power source for subwoofers with its enormous stored energy capacity of 340 joules, and peak output current capability of 37 amperes per channel. Two critically acclaimed BGW GTA output modules, housed in a custom 144 cfm, servo-controlled fan enclosure, provide 1900 Watts of continuous power, almost 3 horse power.

The speakers used in both models were designed especially for this application. Each 15" driver uses a 4 ohm, copper edge wound voice coil. Two speakers are driven in parallel from each GTA amplifier module to optimize amplifier to speaker power transfer. The drivers are rated at 600 watts each, matching the available amplifier power of 1400 watts IHF per module. A special rubber surround and rugged spider result in exceptional excursion capability. Following BGW's long tradition of modular designs, the 16 pound magnetic structure is attached to the cast aluminum speaker basket with three bolts, allowing for quick replacement of the entire moving assembly. There is no need to replace the entire speaker, or send drivers out for re-coning.

The M2200 enclosure is fabricated using 1" MDF composite, with 2" MDF forming the baffle, while the M1100 uses Baltic birch plywood. Generous porting reduces distortion and power compression. Both enclosures are tuned to 30 Hz. Ample internal bracing further stiffens the enclosure and eliminates resonances. The amplifier/processor assembly is housed in a separate chamber on the recessed back panel. For safety, protective corners and 14 gauge steel speaker grills are included on all models.
