My wife has a dance troupe and we need some sort of music set up that would be loud enough to hear outside or in a large hall. We were looking at disco speakers and amps ,but have not got a clue on what to get. Had a look in maplin website seen some things but clued up on it. Could anyone help on what to get and how much to spend. We need a good set of loudspeakers.highpowered amp with inputs of cd player etc.
