Operate this Sub on a Onkyo 7.1 AV receiver, connected via a cable Oehlbach Subwoofer (is the included RCA cable is not recommended). These large Sony-standing speakers, center speaker Sony midsize, and small magnate surround and front high speakers in Dolby Pro Logic IIz mode. Transition frequency set on AVR to 150 Hz, and bass with double-bass option even further by raising the AVR. Volume on the sub so psyched to about 40-50%. The sub is our center under the plasma TV and the center box, in a TV rack made of wood. The Sub radiates to the side (about 10 cm from the wooden wall of the rack) and by firing port forward from, and thus uses even the entire Rack as a resonance chamber. :-) The sound is simply overwhelming, absolute cinema feeling in a 25 sqm large living room at 4.5 m distance from the seating position. Also bass heavy music, such as trance comes over super clean, space-filling and rock hard. Genial, hard to believe. Here, the AVR is only at 35% of its power, and the sub at 50% ... Even at this level one begins to feel the bass waves on the body! More untwisting I did not dare because of the neighbors ... The optics and processing of this sub is noble, the on / off switch, green power LED and volume control at the front are very practical. He should when not in use but off completely, otherwise it draws about 35W in standby. Unrestricted buy rating, 5 stars!
