I'm using the EV ZxA1 speakers with arranger keyboard and guitar. I got them as soon as they came out. Love them. Got rid of the Peavey stuff, Roland amps, and all that. Didn't sell my Bose Model II (as yet). I work 5 nights a week, mainly dinner/cocktail music with some dancing. Not the thump thump variety. These speakers are great for my purposes. My largest groups would number about 150. Don't have a sub and don't feel I need one. For small dinner parties, I'm using two of the new, very small, Behringer powered monitor speakers with the arranger. Works great and very light-weight.
