DUNLAVY SC-VI

Room build means that I am purpose building a room for audio listening. Everything will be acoustically optimized including room treatments. Audio processors make me cringe even though they can be very effective. I think I have the width thing down pat, I am more concerned about low ceilings. 9 foot at the front wall and 6 foot at the back. 7.5 foot ceiling height 10 feet from the front wall. This means if they are 2 feet from the front wall, listening position should have a 7 foot ceiling height roughly. Perhaps I should place the speakers at the short wall facing the other way ?

Now I am thinking about raising the roof 3 feet, which would give me a 12 foot ceiling on one end and a 9 on the other. I need to roof anyways so I could do this all at once. Am I nuts ?

A lot to consider. The room is being made out of an existing structure which is empty and stripped to open wall studs and open ceiling joists. The slab it sits on is within inches of 20 x 20. If I keep it 20 x 20 then I do not have to do any new roofing, supporting walls, etc.
Putting the speakers on the short wall makes sense to me acoustically since it makes the room more "amphitheater" like.
Kind of like a horn. The only deal, is that I wanted to also add a Runco and 120" screen for a... dare I say it... um... home theater... the 9 foot high wall would be ideal for a sreeen.... perhaps I could do an automatic drop down screen a little off the short wall, so I do not have to try to mount it on a 6 foot wall...
