Compact Portable setup?

[Rockrz]

Well, that sounds OK but I was hoping to find a single box that isn't that heavy that contains the speaker, mixing board and have line out to be able to use a laptop as the music source.

I know VocoPro has some stuff like this but I was wanting to know which unit provides good quality. It wouldn't need to be really powerful cause high volume is not going to be needed like it would be in a bar or nightclub.
