Hi,
I'm putting together a music system for a medium sized bar/club, and wanted to get as many equipment recommendations as possible from musicians (before I spend lots o' money). So please, if you have any opinions related to: PA systems, Subs, Amplifiers, Soundboards, etc.. I am just trying to ask as many seasoned musicians I can who know what a pain it is to play somewhere with a crap sound system.

The place is medium sized bar atmosphere, about 2500 sq.ft., decent stage for at least a six piece band (drums, keyboard, stacks, etc.). Thanks for your ideas.
