We use a 250W active monitor which has it's own EQ. It is intened for FOH so needs a small purpose made wedge under it to point it up at us (no big deal). We are a 4 piece and TBH only 1 monitor is enough for the various stages we play on. We have vox and guitar coming through and our drummer can hear them both fine. Ours was and ex-demo, cost £150 and HAS plenty of headroom.
