What is your overall opinion of this product?
I have used it indoors outdoors (a Park) and it kicks butt. I don't know what Pete B is using for speakers but, I am using low cost Peaveys 15's and Yamaha 15's with a 18" thunmper and I get more power than I can use. I like it loud. I can't push them pass 5 on my board outdoors because it screams so loud, and my amp is only at 3/4 full. If you can't get the sound you want out of them then its your setup/application. I wouldn't do a large venue unless I had a few more of these, but I would be confident in knowing I could. If you can't get the sound out of them you want contact AMS Techs they can help you with your problem.
