Glad they worked so well for you, my experience with the same DIY project was equally revelatory. It is likely that a couple of panels at the corners of the 22' wall and ceiling juncture would further improve the sound. In my room I found the first two panels improved the sound the most, further panels have yielded smaller incremental performance boosts. If one doesn't avail themselves of professional room analysis, there's going to be elements of guesswork and luck whose results amateurs can't anticipate.
Acoustic Sound Treatment
I have installed 4 DIY 4'x 30'' Jon Risch's sound panels.
Three went on the back wall covering four French doors.
The other went on a side wall at the first reflection point. The other side is a open wall.
The result I got is almost unbelievable. I never dreamed that these panels would change the sound so much for the better!
The music was all over the place before the panels. Now the soundstage is where it belongs and the sound is more focused. LP's that I thought were not recorded well are indeed right sounding.
This audio hobby done right must hit on all cylinders to reach the ultimate end. One of them is sound treatment. We can disagree on cables etc. but you have to be BD&D not to hear a difference in a properly treated room.
The back wall ceiling starts on a upward climb to 22'.
Would two ceiling corner panels help out to further treat my room?
