People have to stop thinking of the Z-5500 as a "computer speaker system" ... I realize that's what they sell as, but there is NO ONE who would use these speakers to their FULL potential in a 'home' environment !!! ... Would they be adequate for a 'dance' gig for 500 people?, I can't say because I haven't played one ... BUT ... I have used the sub in a large outdoor setting, and augmented by a couple of 'slaves', they certainly were MORE than adequate ...
They ONLY way to find out is to try them !!!
