AudioSource has developed the PSW112 with the home theater enthusiast in mind. A 175 watt low distortion amplifier with a 100 dB signal-to-noise ratio has been matched to a 12" mineral-filled polypropylene subwoofer. Front mounted controls allow ease of adjustability for the variable 40-200 Hz low pass crossover and amplifier gain. The bass reflex cabinet design yields twice as much low-end output (+3 dB) as a similar sized sealed subwoofer cabinet. When used as a dedicated Low Frequency Effect (LFE) subwoofer, the 30 Hz response (-3 dB) will be sure to shake the house. Stereo summing analog audio line-level and speaker-level inputs also allow this subwoofer to be setup for 2-channel listening rooms. Removable cabinet feet allow for low profile installations.
