Is it better to have the centre speaker higher than the front L/R rather than lower? I've got a new tv stand which has smoked glass doors on the front but when they're open they don't fold back on themselves so having the centre speaker in the cabinet means that I will have to keep the doors open most of the time which doesn't look very nice. The only options I have are to either take the glass doors off which will spoil the look of the cabinet, or have the centre above the tv. However I'm not allowed to have it sitting on top of the tv so the only soltion I can come up with is to build a shelf that sits on the wall behind the tv, at a height just above the top of the screen, would that work if it was further back, than the front speakers? It would be about 400 - 500mm higher then the front speakers but at the moment it's about 400 - 500mm lower.
