Thanks for the quick response. My seating position will be a little under the center of the screen vertically. Should I try to get the tweeters ear level with the listening position or centered with the screen. To get them ear level I will have to orient the m80's upside down. For that matter, maybe I'm splitting hairs here, but if ear level, being the m80 has 2 tweeters and two midranges, if ear level is the way to go, should I try to make ear level between the tweeter and mid woofer.... I may really be over thinking this
