Minimum room size for Wilson Sophia II


I'm looking for help resolving an issue where music can be heard outside my house with doors/windows closed. The the speakers are in front of a sliding glass door (covered w/moving blankets).

One, possibly two ideas to resolve this:
1) Place sound blocking acoustical material in front of the glass w/ dead-space between layers.
2) Move speakers into a smaller room: 11.6' long (140") X 10.5' wide (126").

From your experience, is the second room is too small?

What removable materials could I put against the glass slider that would drastically reduce the sound?

System (106 db):
Wilson Sophia II
McIntosh MC501 500W monoblocks
McIntosh C500 tube preamp
Audio Research DAC7
Fully balanced system w/Transparent Super cables

My S3s are in 12'x 18' room with a draped sliding glass door behind the speakers and they work fine. The key is getting the WASP done correctly.

Primare_cd31,are your S3s still on the casters?
Primare_cd31, yes the S3s sound better when they're spiked and leveled, especially in the bass region.

I'd recommend having your dealer do the WASP, and remeasure
the room before you invest in a lot of room treatments.
