I was looking very hard at things around it that could possibly be vibrating and tricking me into thinking it was the 800 as what happened previously to me when it was just barely resting on the wood frame, which made it sound very similar actually.

Ok I tell you what, now that I have that possibility stuck in my head I think what I'll do is move the sub out of it's location, away from all the stuff that surrounds it now, and see if it still sounds as f it's bottoming out. That would be so awesome if it was something else entirely and not the speakers themselves. Because like I said they perform flawlessly during music playback. If I could get that kind of performance out of them during movies (or perhaps even better), I would be as happy as a pig in shit!

Of course wouldn't you know I'm not at the house right now. So now it'll be driving me mad wondering if that's the culprit until I can actually get home and tinker with it!
