Hi Larry. Interesting to hear that the 38 lb KP-100S stereo PA unit can function both as a 'monitor' and 'sole sound source' for the smaller venues. I trust, as you explained, that its bass response will be impressive, but . . . I'm concerned about potential feedback when placing the KP-100S 3 feet directly behind me, with the microphone effectively pointed in the direction of the speaker.

The nice advantage of the Carvin system is that it's 18 lbs lighter than the Sound Motion KP-100S. In this biz there are so many widely varying venues to consider, yet not one PA system seems suitable for all of them. My pocketbook and closet space isn't big enough to hold them all, so . . .
