dont own any but I was actually talking with a dealer not long back who has a pretty extensively treated room and he was commenting that their experiments found that the 1.7 needed to be tilted back quite a bit further than the stock mounts allowed to sound "Good" no reason to doubt this or suspect room treatments were somehow flawed but you may want to also look outside the normal range of adjustments as well. sorry for the semi off topic.
