This subwoofer amplifier works perfectly, cosmetically overall ok, but the volume knob is bashed a bit due to a shipping issue. From the web: "The Amplifier The amplifier is a dual-mono design. It uses a toroidal transformer with a split supply to each channel. It has an adjustable 12 db/octave crossover, with a range of 30 to 200 Hz. It puts out 150W RMS @8 ohms and 200W RMS @4 ohms. The technology of the amp is Class D half- bridge PWM, using this “cutting edge class D technology to accomplish its power transfer. The extremely low impedance of the amplifier over the low frequency range provides near perfect signal transfer to a non-resonate load. Stable and low impedance assures linearity of the signal transfer to the load through proper cabling.” It has controls for volume, phase, crossover point, subsonic filter and auto standby. It can be used with a normal on/off or in an auto-standby mode. This mode automatically turns on amp if it detects a signal and turns amp off if signal is not detected for a period of time. It has input for both line level RCA and speaker level 5-way binding posts. The amp operates with either 120v or 240v with proper adaptor. The build quality of the amp seems very high for its price range. It looks good enough to go in the equipment rack with high-end equipment."
