A common rule of thumb: Under 16 ft deep, so rears would sit right on top of you — a 5-channel bed is the better fit. Two subs in opposite corners even out the bass across the room. Ceiling and floor area both suit four overheads.

2 notes on this build:
Room for a second subwoofer — This receiver has 2 independent subwoofer outputs and the build has one sub. A second subwoofer on its own output — each dialed in with its own distance and level — evens out bass across every seat far more than a single sub of any size. A common, high-value next upgrade.
Getting 4K120 gaming through this chain — A 4K/120 chain needs an Ultra High Speed (48 Gbps) certified HDMI cable; over a short run (under ~10 ft) any certified Ultra High Speed cable carries the full 48 Gbps.
