We've only had this long enough for one gig, but it worked very well. I had a couple of friends in the audience (this was an outdoor event), and they said that everything was clearly audible. With an acoustic band, that's the most important thing.

I got this mainly as monitors for my Yamaha mox8 as I was not vey happy with my Behringer ULTRATONE K1800FX 180-Watt 4-Channel PA System. Please don't get me wrong I am not saying Behringer ULTRATONE is bad as it is also a very good system for its price and produces good quality sound.However...

A few years ago, I purchased a STAGEPAS 300, and I used it about 4 or 5 times a week. I play me bass guitar through it, and also use the other inputs for keyboard and vocals. After hundreds of hours of use, something shook loose, and it quit.

Simple and straight forward, my family has loan it to our Church for their weekly meetings. I show them one time how to hook it and they love it.
