I’d recommend having at least a 5.1 setup, but I’d wire for a 7.2 system since it’s very cheap while the walls are down and gives you the flexibility to expand later if you get the itch. Especially with an 85” screen you want the sound to match the scale and immersive qualities provided by a nice TV that size. I once did a home install where the guy invested in a nice $20k surround system but would only buy a 42” TV because he wanted it to fit in his damn antique cabinet. The sound was so much bigger than the impact of the TV it was a mismatch from an enjoyment standpoint. As with everything in audio and HT, balance is key. Best of luck.
Is a home theater even worth it or doable?
Please be honest with me. I'm a huge TV movie fan as I'm sure many of you are, and in my youth I used to have a Denon setup, blu-ray, etc. I loved the experience. Fast forward 25 years and now I just stream my tv and movies off Netflix, HBO Max, and Hulu. We are doing a new addition where we have an open space concept. I see myself continuing to stream in the future, but would like a clean sound at least. I am treating myself to an 85" TV not sure the make model yet, but I want a big one. Does it make sense for me to even invest in something more then a sound bar given my streaming and open concept? If so, what type of setup should I consider or if I should prewire something up and where would that be? Thanks for your advice.
