I am not a fan of CV at all. Yes they can get loud, but how loud do you want to play crap? Wouldnt you like to be able to hear the music? I've had 2 college roommates, who lived by CV, and personally, I'd rather buy Sony speakers.
/shiver.
If you need something loud and clear. Something that won't embarass you at parties, buy a few JBL Pro speakers.
DJ's, Studio's, Movie theaters, clubs, etc. all use them for a reason.
I have a JBL Pro speaker. ~1300watts RMS, 135db, clear as a bell.
If you don't mind used, You can find them on ebay for $300-$400 ea. New, expect to pay ~$1000+
