About the BPS-400
The Mirage BPS-400 is a high-performance powered bipolar subwoofer weighing approximately 110 pounds. It features two 12-inch heavy-duty drivers and a 400 watt nominal (1600 watt peak) Pulse Width Modulation (PWM) amplifier with 90% efficiency, which generates less heat than typical analog amplifiers. The subwoofer has a frequency response rated down to 18Hz (some measurements suggest 16Hz at 83dB), providing deep and accurate bass. It includes a continuously variable low-pass filter adjustable from 50Hz to 100Hz and three line-level inputs (left, right, and mono). The enclosure is finished with a black piano-gloss top and removable cloth grilles on each side. Dimensions are approximately 22" high x 23.5" wide x 20" deep. The BPS-400 is praised for its musicality and room-filling bass performance.
