Very biased opinion with me but I'll also vote R11's. When I heard them I was quite impressed that the little things I didn't like about the previous R900 (larger drivers less controlled) has been eliminated with the new series.
Plenty of bass there for 90% of the music most people listen to, but either speaker would benefit from true subwoofers to give frequencies below 25-30hz the force they should have.
