Quote:Exactly. Since you don't know whether whether those factors will have an effect or, if they do, how much effect, it is worth trying to place subs where they might keep modes from being excited (null locations). In the other thread, it has worked for people with asymmetrical openings in their rooms. There was a chance it might not have, but they were glad they at least tried.
Placement has two huge advantages: it's free (doesn't cost anything to move a sub) and it isn't permament (don't like the results, move the sub back). So if Floyd Toole says that placing a pair of subs at the quarter points of room width will eliminate (or minimize) my first three width modes, I'll give it a try. Nothing to lose. If it turns out he was high at the time he wrote that, then I'll place the first sub where it gets me the best response and place the second sub where it adds the most improvement to the first sub. But I'm not going to reflexively dismiss Toole's suggestion as an impossibility.
