Hello, Just wondering people's thoughts on the best height for speaker mounting on the wall for rears. This is a pretty standard living room setup with a couch and a couple of armchairs (nothing with realy high backs). I've always "heard" that the rears are best just above ear level (ear level when seated), but I'm wondering what people's experiences are. I'm thinking around 6' up but even considering up to 7' so that people don't bump their head if they walk by/under it. I don't want to go much higher than 7' as then the speakers will have to angled so far down I think it'll ruin things. TIA, Mike W.
