Hi all! First post...long time reader. I'm putting together my first HT setup and am looking for speaker recommendations for my large room. I'm figuring on either M60 or M80s, VP150, & QS8s. I have a Denon 3805 refurb on the way. Do you think I should bother with 6.1 or 7.1 rear surrounds due to the back wall being so far away? What are your suggestions for a great sub in such a large space?

Thanks to Dave (al1en) for the great audition. It was great to experience my first awesome HT setup. WOW...that's a big sub Dave! I wonder if a SVS PB12–Plus/2 will be enough for me?

Here is my plan, which is pretty much to scale.
