So I am almost finished with the room. It took a while...4 kids and a wife. But here are some pics. I went with a 5.1.2 using the RP-280 5.1 system, 2 CDT-3800 ceiling speakers, and a Marantz 7011. The Marshall is actually a mini fridge. The sound panels and diffusers are from GIK acoustics. TV is a 65 LG OLED. The room sounds great.
