Home Theater Virgin

[Grinningcat_o3]

Basic inquiry here, I’m brand new to the home theater game. I used to be heavy into DVD’s back in the day, but once blu rays came about, I just got frustrated at the seemingly never ending technological upgrades and never embraced the blu ray era. This being said I just recently decided to enter the 4K UHD world as it seems to that me for many movies this is probably the best we’ll see them in our homes. Anyway, I recently sort of blindly invested in an LG CX OLED, Sonos Arc, and a ps5. I just want to make sure I’m getting the most of my setup and not doing something wrong, is anyone on this site running a similar setup for home theater viewing? Any tips if so would be appreciated. My main concern right now is my sonos arc, am I missing out on anything by going with a sound bar vs a receiver type system? Seems I can achieve 5.1 by investing in a pair of speakers and a woofer, but don’t think I can ever achieve 7.1. I could potentially return the Arc and get something else. Any input is appreciated, thx!
