.I'm impressed, it goes all the way to 5k! with JBL's own traditionally very low distortion (between -30db and -25db @ 100W). Its about 99.5 db till 1k where it fluctuates between 100 and 102db before dropping off steeply at 4.5k (-5db@5k, -10db@6k).

I might just order a few more, one of these and a high power piezo would make a killer guitar cab (so would four :-)).

You can't often get a cast frame 300W 15" JBL for 50$ and free shipping.
