Bookshelf speakers that can be mounted on the ceiling for Atmos

[hifipartpicker]

I had decided to buy four in ceiling speakers for Atmos. After watching this video, I realised that bookshelf speakers are the way to go.

Could anyone suggest a pair of bookshelf speakers that can be mounted on the ceiling.

Hete are my picks:-
Monitor Audio 50
Polk Audio OWM3
Fyne Audio F300


My budget is 70k max for 2 pairs
Thanks in advance
