Denon X4700H & LG C9: Upgrading a 2012 Home Theater to 4k OLED & Dolby Atmos Surround Sound - Part 3

This video series covers upgrading a 2012 era Home Theater system to the latest 4k OLED TV and Dolby Atmos Surround Sound.

My media room is:
13 feet (TV to couch direction) deep x 16 feet wide.

Part 3 shows finishing up replacement speaker installation.

The 2012 home theater had a Sony 34" KD-34XBR970 high-definition TV, a Denon AVR-2807 7.1 receiver, and Onyko SKS-HT540 7.1 speakers.

The upgraded system consists of:
LG C9 4k OLED with four HDMI 2.1 ports
