DE has made some negative comments about broadband absorbtion, e.g.
and I note that aiming a surround at a corner trap isn't a great idea, but that said, I think that if you have no other treatment in a room, and have measureable modal problems, then DIY corner traps are worth a go for combining cheap and effective.
There's a couple of examples of absorbers at the end of this page
the most relevant are probably

http://forum.studiotips.com/viewtopic.php?t=534 (4" thick at corner)
For the superchunk style, there are three cut patterns that effeciently use all of a 2'x4' sheet of rigid fiberglass, depending on the size of the diagonal you want.
For 24" and 34" please see http://forum.studiotips.com/viewtopic.php?t=535
For the 48" cut pattern http://www.bobgolds.com/CornerTrapCut.GIF (SuperDuperChunk)
I don't want treatments are are super intrusive in the room. No offense to Ethan, but his traps just wouldn't go over well in my room. Tubes could probably be blended in a little better, but my better half still didn't like that idea. These wedges are probably the least intrusive, so they'd be my best bet as far as WAF goes.
I'll read up on the link to DE's posts....
