Paul,
> Bryan, I notice you did not mention the potential use of any tri-corner traps such as those by ASC, RealTrap, Eightherve, etc. <
One of the problems for Bryan and me is we want to help people understand their rooms, but we don't want to come off as shills for our companies or get into a discussion of the pros and cons of
other company's products. With bass trapping (and all acoustic panels for that matter), size is everything. Assuming an effective product in the first place of course. So I try to stick to theory and what's practical, and I'm sure Bryan does too.
That said, all you really need is a bunch more RealTraps.
