The QSC hpr/k/kw are of such quality, they almost seem to have become an industry standard over the past several years in my area. Any person in the market for quality active speakers ends up going with them. Also, they offer a 6 year warranty, which for mobile speakers, is unheard of. I have the HPR 12’s and a KW 18, and couldn’t be happier. I’ve been using the tops every week for 4+ hours, and really pushed them a lot with no problems. Same thing with the sub, but I’ve only had that for about a year now, compared to the HPR’s, which I’ve had about 3 years. With that warranty, you can’t beat what you get for the money.
