Is my room OK for Magneplanar 3.6's

Probably too small, especially being square. I have a pair of 1.6s in a 15 x 21 x 8 room. 6' off of the front wall, 30" of space between them and the side walls. My head position is 2' from the back wall. It sounds good, but not as good as when they were in a larger room. The back wall is key. They say 3' will do, but that is a stretch in the same way Magnepan claims that one can get away with only 50 watts or so. This is with wall treatment behind the speakers fwiw.

Work is one thing, optimize is another. For example, Elizabeth's setup described above = work. Does NOT = optimize. Find another room or a different speaker is my advice, sitting 7 ft. from maggies is not the way to get the best out of them.

Shakey

Yeah, my arrangement is just a working one, with what I am given. Most folks do not arrange where they live around the best stereo system setup!! (me either!) I got what I got, and did the best i can do with that. I almost had a chance to move into a huge one bedroom apt with a 36 ft by 15 living room! But it did not happen. A pretty rare place. The other apartments there all sucked, only four units were like the one i wanted. Too bad.
Where I now live is gonna be it for a long time if I am lucky. it is nearly the same size and layout as the last place and I lived there 17 years.(I hate moving)
When much younger I lived in a tiny place and had Infinity RSIIa's in there. I loved them.

Magnepan's are best in a rectangular room, and one larger than yours. I would speculate that you will have some strong room modes with any speaker that has any bass output. One wall where the dimensions are 15L by 15W by 15H will create a big problem.

Do you have a system in this room now? If so, how does it sound to you? I would think a pair of small 2 way stand mounts would offer a better match to the space.

I had ADS 810's in there before. Sounded fairly good. Then I put in Gallo Micro Ti's with a Gallo TR3 sub and that sounds also fairly good. The other speaker I was considering -- and clearly a whole different experience - was either a B&W CM8, CM9 or maybe 804D. Any ideas whether these would work in this space? Thanks again.
