Thanks to all who have chipped in here. I use two M-Audio BX5a speakers placed usually on the floor right under my keyboard stand - nothing fancy here. For the type venues I play they provide plenty of sound even when turned up only 75%. Only a few times have I been in a really noisy place and it is very hard for me to hear what I am playing in those venues. I guess the least cumbersome approach is to put the speakers behind me and see how that helps.
