I agree with Atmasphere in that I have always believed that if a speaker is better with certain types of music than with others, it only points out that the speaker is weak in some way. A really good speaker will perform equally well with all kinds of music. Choosing a speaker for one kind of music is only surrendering to it's shortcomings elsewhere.
If you want a speaker that is great for Rock, beyond being a really good speaker to begin with, the only real requirement is that it be great at very high volumes.
My 2 cents
