This was a retrofit project. We were faced with a couple of challenges when we opened up the walls for speaker installation, like plumbing pipes where we needed to put our speakers. It didn’t stop us though. We called our skilled plumber and had him reroute it. 5.1 Audio setup in Media Room with 80 inch Sharp Display. We used Triad speakers and and a current spec Marantz AVR to drive the system. Custom Millwork housed all of the gear, the center channel and the Sunfire Subwoofer.
