PA for my band

  • I am in a cover band and we rehearse in our drummer's garage. we have a crappy pa that is just not loud enough to keep up with the amps and drums. We want to play some small outdoor parties in town and want to get a better PA system.

    I have an Antelope Audio Orion Studio with 12 mic pre's and 4 on-board mixers and would like to use it so I just need power and speakers. How big should the speakers be and how powerful of an amp? We will blend the whole band, guitars, bass, drums and vocals through the pa but it needs to keep up with the actual amps and drums and I am not sure what to get.

    What should I get for my 4 piece party band? I have heard about QSC K12 but would be curious about others.
