there is matching speakers to go with them that are better than anything i've heard under the 3k mark.

there is even a matching subwoofer.


Also look at the loudspeaker kit in leedy they have some amazing value for money speakers. They use vifa / scan speak drivers which you wont find inside retail types of speaker for under 5k.

Whatever you do don't buy bose, but i suppose you couldn't afford to spend 8k on $80 of speakers anyway :P
