TOA is a well known brand for Pipped in music...although industrial standard, could be the one for you too.

But that depends on your 'house' size, rooms etc.
Since you are going to hang speakers from the ceiling or stuff, you better get a good contractor to do it.
Hey, here is something radical, i dunno how it works, but could be a solution for you too:
http://forum.lowyat.net/topic/1532596Before you get anything, do a lot of homework abt this stuff. You could even get cheaper stuff than TOA at Jalan Pasar is you know what you want

But if you want a really simple setup for a restaurant example, just get any China Amplifier and some JBL Control 1 Clone speakers will do
