Wilson Audio Duette Series 3

I have an 11x11 dedicated music room and I use Sabrina X’s, about 2 ft from the wall and about 2.5 ft from each side.They sound fantastic.

I think the Sabrina not only does well close to the wall but requires it to have good bass. The bass takes a dive pretty high but is nice and flat with some room gain. 

I had the Duette 2 series and it is a great speaker.  It plays in tight spaces.  They come on the used market from time to time.
