ls50w II's for "home theater"

hi…first post here and need some help. without adding an AVR, is there a way to use my LS50 w II’s as main fronts, with KC 62 as sub, and connect a JBL 9.1 sound bar for center and surround pair from rears, along with an Apple TV 4K (2022 version when it is released) and a LG or Sony OLED with eARC?

sounds like a recipe for disaster…syncing all the different devices audio (even if its possible to combine) wight be not worth the trouble.

thanks. perhaps. I haven’t connected my LS50 w II’s to the TV yet, and am concerned that audio from movies won’t be great. I could do without ATMOS as long as the “imaging” is great from just the fronts.
