In my opinion the Barbettas blow away most all traditional p.a. systems unless they are biamped. They each have 4 input channels, but you can use them with a mixer, as I usually do.
Downside is they are very expensive and it's almost impossible to find the used, because once you buy them you don't want to sell them.
