That’s a good sized room, and if you are interested in pursuing good room acoustics, you have enough space to play with, so that you can pick the best placement for all your gear.
Couple of questions though:
Is the room open to other areas?
How high is your ceiling?
How far would your LP (listening Position) be from the front speakers?
Is this your first go at building a good, high quality rig?
Usage: HT to Music?
