The Subwoofer is in great shape and would be good for any 5.1, 6.1 7.1 audio system. But there are a Two cosmetic thing with the subwoofer. The front speaker screen has some small imperfection and there is a scuff running down the lower left side of the subwoofer. Other than those two things the Subwoofer is in working order. All the info on the Subwoofer is below, Thanks for reading Powered subwoofer: RM6750 bass-reflex50-watt RMS amp8 front-firing Dynamic Balance woofer11W x 15-7/8H x 13-3/8DMaterials: The RM6750 subwoofer is made of durable MDF with a black vinyl finish.Recommended Hookup: The subwoofer can be connected several different ways, utilizing the speaker level inputs and outputs, or the Line input. The subwoofer features spring clip terminals for the speaker level inputs and outputs, plus a stereo RCA line input. The recommended hookup methods are as follows:Recommended Hookup A: Polk Audio recommends connecting the amplifiers left and right front channels to the speaker level inputs of the subwoofer and the front left and right satellite speakers to the subwoofers speaker level output. The center and surround speakers are directly connected to the amplifier. The amplifiers bass management/speaker setup should be configured with the front left and right speakers set to Large and the Subwoofer set to Off or None.Recommended Hookup B: An alternate hookup method is for the subwoofer and front speakers to be connected in parallel directly to the amplifiers front outputs. The center and surround speakers are directly connected to the amplifier. The bass management setup is the same as Recommended Hookup A.Line Input: This stereo RCA input allows you to connect to an unfiltered subwoofer output on a receiver. You will need a Y adapter to connect a mono subwoofer cable to the stereo line input.Phase Switch: Speaker positioning can sometimes cause subwoofers to work against satellite speakers instead of with them, creating frequency canceling and a dramatic loss of bass. When this occurs, you can switch the phase of the subwoofer driver from Normal (0°) to Reverse (180°), to enhance the bass attack.Volume: The subwoofer has a separate volume level, allowing you to adjust the subwoofer relative to the remainder of the sound system.Slot-loaded Bass Vent: The powered subwoofer features a slot-loaded bass vent on the front panel just beneath the woofer. The slot, 9 x 1, dramatically lessens turbulence, noise and distortion, enabling the subwoofer to play precise, thunderous bass.Subwoofer Positioning: The RM6750 subwoofer is not magnetically shielded and may cause picture interference if it is placed in close proximity to a TV or computer monitor. For best performance, the subwoofer should be placed at least six inches away from a wall.
