Hi guys/gals last night I purchased the RM6900 speaker set while I was going to circuit city to replace my sub. I was planning on going there to replace my sub that was ruined by nature and after the guy at circuit city let me listen to this system I was in love.
Last night I didn't have a chance to run and configure everything completely but there was one thing I noticed on the sub that had me a little concerned. While the sub was on Auto mode and in standby at the time I keep hearing a (thump thump) sound. It was very low but very deep so it was easy to hear. It almost sounded like a heartbeat and sometimes it would slow down and then speeed up. Does anyone know what that could be? Could it be getting some interference from somewhere? I'm headed to Circuit City today to pick up a better subwoofer cable and that could solve it but I just wanted to get some opinions on it because its really distracting.
