I also can recommend the M-Audio GSR series. Has LOTS of positive user feedback (not store/manufacturer generated) so I took a punt.

They sound really sweet and are the FIRST PA set I have bought that did not need any tweaking (including the mighty Bose L1 model I and II) out of the box.

Simply set them up turned them on and began to play. And the price is astounding!!!!

I did buy two tops and the sub, but so far I am only using a mono system 1 top and 1 sub...sounds brilliant. Better imo to the Bose.
