The extraordinary ForceField 5 incorporates all the advanced technology and innovative concepts introduced in the ForceField 3 and 4 in a larger and even more powerful low-frequency beast. The ForceField 5 combines a long-throw 12" subwoofer (which incorporates a huge high gauss magnet structure) driven by a GoldenEar-designed DSP-controlled 1500-Watt digital amplifier and pressure coupled to a downward-firing 12-3/4" x 14-1/2" quadratic planar infrasonic radiator.
