Bridgman,
I know the consenus to most tends to fall in favor of the M60's or the M22's, but I decided on the M50's. I've had the opportunity to hear both, the M50's and M22's, and the M22's were sweet, but I favored the M50's. Right or wrong, I can't help it. Just my taste and preferences I guess. lol
Anyways, in answer to your other questions, my room is longer than it is wide, so I guess one could say it's long and narrow, but it isn't real deep or real long, it's about 16' deep/long, and 11' wide. The distance from the center to my listening position is right around 8-9 ft. Probably about 8 1/2'.
