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

I'm currently working with an acoustic engineer to custom a solution. I'll post new pictures and results once completed.
After measuremetns, etc, the acoustic engineer did identify the best seating position and speaker placement for my room without any treatment. One speaker was moved way off a side wall while my listening position was kind of being moved way off the centre of the room width axis. This position won't pass the WAF

I just had my room modified and a different Wilson dealer set-up my speaker using the WASP method and they sound great. Off axis they don't sound as good, but in the sweet spot they are incredible.
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.

Yes they are still on casters as I still need to work on the room acoustic treatments. Speaker placement may need to change once treaments have been applied. Do the S4's sound much better on spike?
Being in a room of 16' x 14.4' x 7.84'. There several acoustic chalenges. I've had an acoustic engineer measured the room and the result wasn't very positive! Basically, i need to tune below 70hz region then from 148hz upward. I'll need to apply room specific tunable Helmholtz Resonators with rear ports, BAD ARC panels and RPG Skyline!
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?
they'll be fine in that room if set up properly and possibly if you do a little bit of room treatment. The size itself is not the issue - It will be a nearfield experience, but that also helps eliminate room reflections and sounds
Thanks for the input! The Owens Corning 705/703 seems like a good fit to reduce the sound going out into the neighborhood :)

Looks like I'm pretty close to the minimum size for sophias, still need to find my tape to measure my listening room.

Tom, since it sounds like you know the dimensions, would you be kind enough to share them? :)
11.6 x 10.5 is way, way, WAY too small for Sophias. The only thing I would use in that sized room would be tiny monitors or headphones.

Minimum for the Sophias to open up is 16 x 18 or so. Larger is better, 19 x 21 is probably about the right size.
You have very nice sytem that is itching for a good room. Gee 500 watt monoblocks and Wilsons in a 12 by 10 room. Cant be a good thing, no matter how much room treatment you do.

I'm currently struggle in getting my room acoustically treated correctly. I've done some researches and would like to share my findings with you.
Firstly, what is the dimension of your existing room? Do you live in a house or a unit? Unless all your walls have high grade acoustic thermally bonded polyester fibre insulation installed between the gyprock and brick. Sound will escape through.
Secondly, how loud do you listen to your music? It isn't a good idea acoustically place your speakers in front of glass doors. Blanket won't help much in taming the bass response down to 20 Hz from the Sophia.
You'll need to cover the expose glass areas with DIY OC 705 panels cover with fabric, wood frame, stand, etc. Get 4 bass traps (able to go down to 40 Hz at a minimum) for 4 room corners. Install at least 2 OC 703 panels at first reflection points and behind listening chair.
If possible, hang a few OC 703 panels or diffusers on ceiling
You can also call in an acoustic engineer to avoid un-necessary/ incorrect placement of acoustic treatments
IMHO, your smaller room is small for the Sophia.
You can use it but you'll need expert measurements, advices on how/ where to apply acoustic treatment
Finally, all of the above will only reduce the sound from escaping outside.
