Best used speaker for $2,000 for rock music

The headline says it all. I am looking for a change. I am selling my Proac Studio 250's. Why? I don't know. It is a brutal addiction. The Proacs sound beautiful. But I am looking for a classic rock speaker. Klipsch cornwalls or something like that. I need to feel it in the gut, know what I mean?
I need to know what the best speaker for classic rock in this price range would be.
Any Ideas?
Thanks
