While I didn't buy the Linbrook Signature System for rockin' out, they are certainly capable of it. The bass is very good - tight, detailed and about as low as you would want to go. I listen to a wide range of music and have found no area where they're weak. Recently I put on some old ZZ Top and cranked it up to near pain levels for the sheer fun of it - it rocked big time. I'm a drummer and the speakers delivered.
As mentioned above, Ty has prototyped some extremely dynamic speakers which he feels are particularly good for rock n' roll. I've seen them (they're size XXL) but haven't heard them. The Linbrooks sound good out of the box, but really start to find their own after 200 hours or so. They're also a very revealing speaker and improvements in your front end or room acoustics will be rewarded.
