$5K-20K is quite a range. There are a lot of speakers in this range that will rock. In fact, I can't imagine a $20K speaker that couldn't rock. I have never heard a Bugtussel but I would be hesitant to take the recommendations of the Rolling Stones. It would be hard to believe that 50+ year old rockers haven't suffered some ear damage.
If you want to rock, then I agree with the Sean. A lot of drivers with multiple woofers to generate high SPL. Montana makes some speakers that will play as loud as you can stand and they will really rock.
