Looks like a nice, sturdy stand. Who makes it?
Well, I'm not sure where your support joists are for the plaserboard, but why not wall mount the telly, and get the same stand again for the video equipment, but put it to the right hand side, so it looks nice and balanced. Then dump the sub in between the Vantages.
That way, it'll look nice, the wooden cabinet can go on ebay, there will be little inbetween the Vantages to screw up the soundstage, and you can party:music::rocker:
Yeah, been there, and your right - it does.
Just place the sub off-centre inbetween the speakers and it won't. In my room, it's the best place for it.
