I'm going to take a second and give another thumbs up for Xitone. I just got mine a couple of days ago and am really happy with it. Fair warning, it gets LOUD! (You don't have to crank it, but where's the fun in not?) Yet, the tone seems on point. I've yet to do a comparison with my QSC KW122, but with the coaxial design of the Xitone (and I believe the CLR is done the same way) I know I will get a better sound regardless of where I am standing/sitting. This is due to the fact that there is no separation between the woofer and tweeter.
Another method of thought here though:
I originally went with the QSC as it matched the towers that my band uses for our live shows (can't remember the model, but also KW series). In theory, I would get the same, or similar sounds as what we get through the PA, and save the sound guy from adding any eq to my channel. So, if you're playing live with a steady PA, you might want to match your mains.
Lately, however, I have been getting some invites to jam sessions and smaller gigs where there isn't always a PA with enough channels to run my rig through. That's what ultimately led me to looking into something like Xitone. With all the positive feedback here, on YouTube, and other blogs, I decided to give it a try.
