UUugh....I have media room envy now.

I'm closing on my first home tomorrow morning. I'll upload some pics of the space I have in mind. And at this point, I'm just in the planning stages and there are a LOT of other things about my new house I want/need to spend money on, which is why I'm going to DIY as much as I can.
I plan to use this room mostly for watching movies and shows from my Plex media server via the Plex app on my Roku TV. Currently I have a Denon receiver to drive speakers with, and coincidentally, am looking at a pair X-Static and an X-Voce and maybe later add sub(s). Placement shouldn't be an issue as this room will be completely dedicated to the audio-video gear.
Depending on how accessible the rooms walls are from the attic space, I may do wiring drops for surround speakers but that's way down the road and not a priority. I just want a good 2ch audio and center channel for video, to get me started.
