How is the center channel working out? I thought that because of the dispersion characteristics of the ribbons placing it horizontally wasn't ideal.
Placing it horizontially is certainly not ideal, but it performs fine given the limitations.
Nice looking room Skiman. I imagine the sweet spot is confined to the width of the center speaker as there would not be any dispersion to either side? How is the the vertical dispersion?
You must sit within the length, or width in this case, of the array. Vertical dispersion is fine, but it doesn't 'project' or fill the room when horizontal.

Skiman. Very nice room! 
Similar to what I'd like to do someday, with a screen that drops down in the plane of the speakers for HT, but the speakers are placed well into the room for good 2 channel performance.
Did you ever post anything on your HT build? Would you be willing to share some info? (did you DIY/hire a consultant/etc.) My wife and I are talking about doing an add on that would be a dedicated room and we're getting close, but trying to figure out where to start w/o blowing the budget on a $$$$$$ consultant.
Thanks.
I haven't posted a detailed build, but I could write a book. It was built from Rives Audio plans, with the framing, drywall, and carpet contracted, and everything else DIY. Took about a year, although it's constantly evolving. Send me a private message and we can talk more.
Correct me if I'm wrong Skiman but didn't you used to have your Center LS9 standing? Could you not get it far enough into the room?
When I first got the third LS9, I mounted it vertically for a few days to hear how it sounded. Nirvana, but the retractable screen prevents this location.
The room was originally designed around Definitive Technology speakers, before the LS9 existed. I had prepaid AV123 for a center (and other speakers) that never materialized. So I decided to get a third LS9, knowing AV123's future was dire at the time. Now that Danny has designed a dedicated LS center, I've ordered one from Ruben at Fallen Enclosures.
