I always thought having the cornwall for center as well for HT would be advantageous as a lot of the reviews mention how brilliantly they resolve vocals. So for center channel duty (speech) i thought they'd excel. However, if the heresy is just as good but just doesn't have the lower end should be fine, I'd love to hear a cornwall vs heresy comparison as well. As to the height issue, a lot of people on the klipsch forum always mention putting the speaker on its side. Cant wait to hear more of your thoughts! I got my RF 7s very cheap (closeout when rf 7 ii came out), so half price brand new. I might have to wait for a cornwall v to get the iv's or get them second hand. Still well outside my price range. I also don't know if now is the right time. Finishing my basement build but we may move in a few years, I wouldn't want to damage them in a move if I can wait a few years be in a longer term place, and be able to get then cheaper. My room is also very small, 12x12 and is be 7-8 ft from the speakers, so not sure if they'd really be able to shine in that space
