Dear Serenity,
Thank you
I found my 50% more serenity.
In reading your totally cool advice for putting some kind of absorption in at least the first reflection points. Decided to make my own 4 by 2 foot panels filled with 5.5 inch Roxul.

Holy crap it's cool, I made 3 of them one on each side and one in back. Immediately my M80s sound stage broadened. Seems more open.

I think they're great and it only cost me about 60 bucks with plenty of insulation left over, possibly another 3 more of them on the way.

Save some money and make your own treatments truly quite cheap.

Thank you , I've noticed an improvement
