Ha that’s right! I even had to pull the sconces off the walls and put weather stripping behind them to get them to stop vibrating.
Yeah... I had all kinds of problems with rattling subwoofers... none of which had anything to do with the subwoofer.
The only thing I could blame on the subwoofer was that my SVS cylinder would make an awful "grunk" kind of noise on very bass-heavy scenes... I had to fix that one by adding an EP500 and turning them both down a bit. Everything else was room rattles.
