In fact, my question can be summurized to the following : "why the sound delivered on a stage amplifier is different of the one i get directly from the speackers i have on my PC"?

Perhaps my question looks a little bit stupid but, the feeling i get from my PC at home (via my ordinary powered speakers) is very good while the one i get on a stage amplifier is very banal ... Some ideas ?

Thank you in advance for your comments,

Merci

It's because the music you play through your PC speakers is compressed, normalized and limited. No peaks. Stage speakers have to be able to handle peaks caused by you or other live musicians clanging a guitar string, feedback, the keyboard player forgetting his volume pedal is on full and hits a big two handed piano chord that takes his head off before he can back off the pedal, the singer drops the mic onto the stage, stuff like that. Any one of those will blow up your PC speakers or even big home stereo speakers in a nano second. The problem is most low cost PA speakers that can handle those peaks sound like crap. To get good sound on stage you have to use professional quality speakers as in JBL, Bose, Mackie etc. Those are expensive and there's no way around that unless you're doing small low volume coffee shop type gigs with no live drums and maybe one other player not going through the PA. For a gig like that the best PC speaker setups can work quite well like the big Logitec's or that big new Altec system. Those still cost $500-700 though but if you're singing through it and get bad feedback one time, you could still blow up the tweeters because comsumer home theater type PC speakers are not designed for a split second high frequency peak that's 300 times the regular output. A good PA speaker like a JBL Eon or a QSC can handle that. And, even the best PA speakers are not going to sound as smooth and warm as your good home stereo setup because that's basically impossible with a system that can handle live stage work. I have heard some really good live PA setups but you're talking big bucks and a qualified soundman running it.
