I have the 5.0's on the dedicated Soliloquy stands. I am using them with the Joldida 302b tube integrated (Acoustic Zen cabling) and am thrilled with the sound. My room is comparable to yours, i.e. 11 x 20 x 8. Speakers are placed on the short wall and about 2' from the rear wall. See "my system" for photos.
Good Luck.
