Have not heard the Zu at all yet. I may be able to get to the RMAF, and listen there. I can also just driver to Utah.
My problem is that my WAF speaker placement means that the back side of the speaker is about 14" from the wall, they are pulled out "half way" so the front of the speaker is exposed by about 6 inches. So overall that I have about 28 inches from back wall to speaker front
My current speakers are Reimer Wind Rivers, which to be honest sound pretty damn good. They are about 14 deep. I have the three year itch.
So.... I understand that the Presence is pretty good with near the wall/corner placement. Any chance the Def's would be ok in this placement?? With those rear firing woofers, I am in doubt.
