I use ATS Acoustics. Fortunately I live in Illinois and travel there to avoid shipping. Easy to build ones own panels.
Owens Corning 703 vs. Roxul Safe 'n' Sound?
I'm going to make some sound absorbing panels to place on the wall behind my listening chair. Owens Corning 703 and Roxul Safe 'n' Sound rigid boards are two choices to make them with. Anyone have experience with both, or even one?
