This thread is making me laugh, it's all over the place and it's all interesting stuff.
Blackmamba, have you given any more consideration to what speakers you might get your sister? Also, are you going to get her a PSA sub? A sealed XS15 would work great in that size room. But then again you could save some money and get a SVS PB-1000 and that would work great as well.
Well I'm thinking since so far I got her some real nice things to start off with, I might just finish it with a little kick. I want to keep my eyes out for a good deal on a decent receiver. Also will be on the lookout for towers and center matching set such as Klipsch. Then one good sub in the corner will do her room some justice. I want to see how it all looks setup after Christmas and see what space and look will intregrate well. I like the PSA idea, they would hook me up for sure!
