Interesting thread. I think the element being not mentioned enough is that rock n roll is usually played loud and is not that sonically nuanced. Much is electric and the drums are simpler and less sophisticated. Taking this into account a listener is able to forego certain design possibly pricey features in a speaker and focus on the aspects of a speaker that highlight this music. Hi efficiency forward sounding drivers or horns do this well. In a perfect world where price was no issue it would be easy to pick a one size fits all speaker for 50K. If I want to listen to a debussy piano concerto I love my single driver full range speakers but ac/dc is not gonna shine like it would on some klipschhorns.
