I currently use the mixer listed above which carries 2000 Watts Peak / 1000 Watts Program / 500 Watts RMS / 2 x 250 Watts RMS . I am considering new speakers and the models which I have chosen are a Rockville RSG15.24 Dual 15 3000 Watt 3-Way 4-Ohm Passive DJ / PA Speaker and same speakers in the 8 Ohm version. First will my mixer work with those speakers and if do which would sound better, the 4 Ohm or the 8 Ohm? There is another amp which I have been looking at as well. Maybe it would match better. It has 4000 Watts PMPO / 2000 Watts Program / 1000 Watts RMS / 2 x 500 Watts RMS. Any advice would be greatly appreciated.
