Acoustic Curtain for listening area

I dealt with much the same situation and thought I'd end up having to do something like this. I overcame it through the simplified Sumiko method of speaker placement. In this method your speaker near a side wall is the anchor. Once you get it placed you start moving the other speaker out away from back wall incrementally until it 'locks' in with the other speaker. 

+1 for Quiet Curtains
I have them in my listening room and they definitely work.

I checked out Quiet Curtains and got a (with due respect) a ridiculously high quote that went upwards of $2000+ with a track...

thank you though !

Thanks buddy - those look nice , might give it a whirl...some of those sound blankets online look like they'll make my room feel like a service elevator...😵‍💫

Don’t be so quick to rule out “cheap” IKEA  stuff. I helped a friend build his room and the heavy black out curtains are well made and did the trick , unless you insist on spending thousands.
