That's a huge room for your entertainment. I'm guessing it's open to other areas? Have you considered having a projector (or both). I built my basement just last year and I ran Cat6, 2 HDMI's (just in case one craps out), and AVI to the projector in the ceiling. I also ran power to behind the projector screen for a future 60" or larger tv. Behind the walls, I ran another Cat6 and speaker wires. All finished with wall speaker plates from Monoprice. I didn't bother running ceiling speakers since i dont' think they will sound very good. Dont' be fooled when it comes to ceiling speakers. I bought the Yamaha NS-IW360 from Amazon.com. I live in Vancouver, so I know that FS is a ripoff for ceiling speakers. Anyways, I just installed ceiling speakers in the common areas such as living, dining and kitchen. They provide background music and that's all. Don't expect high end sound from them (and I think that's for all brands). You have to remember that it's a speaker mounted in between your ceiling joists, so you really don't have a full enclosure for the speaker. Basically, you get nice full range sound, but a bookshelf will blow it away.
