This is my two-channel listening room. The room was very noisy. The panels helped reduce reflections which warmed up the high frequencies and seemed to have improved the bass as well (most likely by just cleaning up the sound). A pair of speakers that can seem bright are many times just victims of active rooms.
I used 3m 77 adhesive spray to bind the burlap to the 703. It was forgiving of mistakes and worked well. Also, I used 4 impaling clips to hang each panel. Leave the back of the 703 open and uncovered in order to use the clips. They do not pierce the burlap easily enough.
