Well Gents, I just had to comment. My situation was a bit of a twist on
@MrBoat 's . When we did the big Reno of 2018 (the whole main floor of the house) I wanted carte blanche for the "Games Room" new Atmos HT system, and my Misses wanted almost nothing speaker wise in the Family Room HT system. Actually she only wanted a small speaker stereo (think those awful Bose Cubes that women thought were "cute"). I figured if I compromised on the Family Room, she'd let me do my thing in the Games Room. (I have a cheap 7.1 HT system in the Man Cave / Junk Room in the basement. Did I tell you I've got a problem? See my signature...)
I did in-walls for the surrounds and smaller bookshelves up front with a wireless Sub on the 5.1 HT system in the Family Room. I got a bit of grief as she somehow thought there'd be no Sub at all, but when I moved it to wireless, she was better with it. The Games Room is a full 7.2.4 Atmos System, and she even encouraged me to "go for it" and buy a 75 inch Samsung QLED for it! When we have people over (and even if it's just us) the Family Room system is never turned on, but folks love to see and hear Concerts (Blu-ray of course) and Sports (Football & Hockey) in the Games Room.
One downside was the Contractor's "professional" painter said they could easily paint the grills for both the in-walls and in-ceiling speakers. Well they messed that up badly, and I spent hours and hours poking out paint from the thousands of holes in all those grills!
And by the way, my wife and I are still married...So there is life after a big Reno.
