I have used this as my Gig setup for the last 2 years I have played crowds of 30 and I have played crowds of 300 and it has done great! The only problem and reason its not 5 starts is if you turn it up to much it does clip and distort quite a bit
I got this because it was on sale and dirt cheap and I needed a PA. It's not the most phenomenal sounding set, but it does the trick, and few people would really notice the relative lack of sound quality as compared to a set of EVs or Mackies or something more expensive. Used them at a wedding with no complaints from anyone.
