Min room size for Wilson Audio Sophia or WP8

Strangely, I found that the Watt Puppies I had did not need a lot of room front to back. They do not boom in the bass, which is very well controlled (and just plain good).
I did use a Pass X350 amp.

more than enough space, but will respond well to room treatments, as all rooms do.

The 11' dimension is going to be the problem. I speak from experience. I used to own Sophia II's and after spending a small fortune on trying to tame the sound in a small room, sold them.

If you are going to set up the speakers on the long wall, you will need at least 1.5 feet from the back wall to the back of the speaker leaving a 6' foot distance from the front of the speakers to the listening position . This is not far enough. Plus, the sound will reflect off of the rear wall causing havoc. If you are going to set up on the short wall, you will need at least 1.5' from each side wall to the sides of the speakers, leaving 7' of space (tweeter to tweeter) between the speakers. This will drastically affect spatial depth of field, soundstage and openness.

Room treatments, cabling, electronics, etc., will help but not cure the situation.

Don’t get me wrong, Wilson's are my absolute favorite speaker. But they need room to breathe to enable them to sound they way they should.

Hi Sergeik: My listening room is 20' x 131/2'. Had Sophias for a few years and
later WP7s, each in various configurations. The Sophias are wonderful. But I was
able to hear all of the differences between the Sophias and the WPs in my apt
that I heard in the showroom. Re bass, I found that I heard all of the differences
between a 10" woofer versus two 8" inch woofers in my space. Maxxs
would be too big for your space, but if you set either of these speakers up well, I
think you'll be fine.

Thanks for the thoughts.

Gpgr4blu, do I get it right that 10" woofer does it better than 2 x 8" ones?
