Polk audio’s RM6750 is a compact 5.1 speaker system for a home theater. The system consists of four stereo speakers, a center channel and a subwoofer that connect to an audio-video receiver with standard speaker wire and a subwoofer cable. Each speaker is labeled on the back to aid in room placement, for example, front, center and right. The red and black terminals on the rear of each speaker correspond to the positive and negative connections, respectively, on the rear of an AV receiver. Warnings Writer Bio
