Background: Started planning to install a home theater into our new living room (as best I could) when we undertook a major home renovation. I'm coming off cheap sound bars and half-decent headsets prior to this, but I always wanted something better. Since planning started, I've been learning, taking the time to get placement as close to dolby's 5.1.4 spec as possible, and buying components.
We gutted the level of the house, insulating and building up from the crawl space up through the new living room and kitchen. It went from a beat up kitchen and useless living room space to an open, nice space for the family.
After all the planning, I landed on the following
LG CX 77" OLED TV
Monoprice Monolith 3 (for LCR)
Revel Concerta2; F36 towers, C25 center, and M16 surrounds
Sanus SF34 stands with adapter plates made out of white PVC sheets
2x Rythmik L12 subs
4x Klipsch R1650-C in ceiling Atmos speakers in foam speaker baffles surrounded by insulation
All in-wall wire is 12 gauge stranded OFC
Couch and ottoman are from LaZBoy (Devon sectional, not sure about ottoman but it has storage in it)
For power, I have a separate 20A circuit just for the receiver, amp, and subwoofers. Both circuits have a dedicated Panamax MR4000, while the TV is on a Panamax MIX-SURGE-G1 surge protected outlet. Second sub is on a Panamax MD2 surge protector. I cut out a shelf so I can keep all the power and network gear hidden in the right hand side of the TV stand.
And yes I know the rug pad is sticking out. I'll cut it once the rug settles more.
Some other improvements to the room include the dimmable, color selectable recessed lighting, and better insulating the entire level (R-30 under floor, R-15 walls, and two layers of R-30 in the ceiling).
