I second the opinion of Cornfedboy. The Avalon's are the best I have heard with all types of music, and rock is no exception. They do it all, soundstage, detail, accurate, powerful bass, realism, and a touch of magic. All the better if you have good gear.
Best speaker for rock music
What is a great, reasonably priced speaker/studio monitor that will really excel on rock/dance/techno? I would imagine this same type of system would also sound great for home theater. I have a small to medium size room, 15' x 13' with cathedral ceilings. I already have a nice audiophile rig but it has the familiar problems with most compressed rock and techno recordings. Thanks, Mike
