Bought two of these for use as full range speakers in our small set up and as tops on our larger PA, the speaker preforms pretty well at both. As full range speakers the bass drivers deliver undistorted lows at about 500W and the tweeters are really crisp, to the point of having to pull back on the EQ, as tops again great the tweeters are really sharp and the 15"driver has no difficulty punching out anything above 150Htz. They are Behringer, will they last? time will tell but 8 months in doing 2 to 3 gigs a week, they are pretty solid.
