This PA system is a good starter one. I wouldn't recommend it for anything larger than a bar. I've used it for a few gigs and have now upgraded but to start out these are good. If you can swing it, I would recommend that you get the bigger brother with 120 watts.
No issues, it was on sale at Guitar Center for $150. 2x 10" speaker monitors included. I am using it as a studio monitor. Eventually I will get a stereo EQ and power amp since the mixer is not stereo and just use the PA for vocals.
