If I were looking for a loud rock n roll speaker I'd probably go active. I actually did go active a few years back when I bought a pair of used ATC 110s for 5k. That was a rare find but those things will really rock. Music Direct sells a JBL line that would be great for hard rock I'm sure. A 12" woofer is great for rocking.
