Yep-speakers are way to big. You may be able to "cheat" the room by putting the speakers on the half wall. The gear between the speakers doesn't help, either. How about investing in a Behringer Digital EQ (if you're on Long Island, NY, I will lend you mine) and spray the room with some noise and see what the curve looks like and compensate with the EQ? If it works, I will probably donate it to you.
Another speaker placement question. HELP
I have my system in a 10foot by 10 foot room which could sound horrible but the front and back walls are half walls so the room is actually a lot larger than 10'x10'. I had the speakers about 2 feet from the front wall and 1 foot from the side walls which was OK but we had our floors all redone so when I put back the system I put the speakers about 4 feet from the front wall and a foot and a half from the side walls. This worked but I found I had a lack of focus in the middle. I towed in the speakers which seems to have solved the hole in the middle effect but I thought I would ask advice on what others would do with this type of room. I am 6 feet from the speakers which are 7 1/2 feet apart but are towed so the tweeter frequencies would join somewhere behind my head. I think it sounds good but any advice would be appreciated. I'm running Hales T5's with Pass amp and pre .I have the front corners treated with foam as well as the foam on the side walls to absorb reflections. I have a good soundstage and it works but what would you do with a room like mine? Please do not say you would move the system to another room. My music space is my only option. Thanks.
