in-ceiling speakers for bathroom - 6.5" or 8"?

[nagooro]

Looking to install ceiling speakers in my master bathroom (already prewired). Are 8" speakers an overkill for a small room?

My setup will probably as per below, unless there are other options I should be thinking about:
- Polk Audio RC60i or 80i
- Chromecast audio
- Amp https://www.amazon.ca/SMSL-50Wx2-TDA...words=SMSL+amp

Appreciate any input.

I have polk 6 inchers and monoprice 8 inchers. Go get some of the carbon ones from monoprice. Much much better.

Go to the Bose store and listen to the 791 series 2 ceiling speakers. They are awesome at all levels, highly recommend!
