The Stagepas 300 (to me) sounds terrific and I get lots of compliments from the elderly who say they can hear every detail. I run my 3K stereo and keep the mixer in the cabinet on poles - doesn't get any easier. It's a very clean sound with lots of punch. I'd move up to the 500 next to handle bigger crowds.
