Mac SE or SE/30 Speaker Diameter Size? (Probably Classic and Plus too?)

[gogopuffs]

Searched all over the forums and can't seem to find where the actual speaker diameter for the Mac SE case is.  I don't have any calipers or my Mac SE on me, so, I'm having to ask the community (and hopefully help whoever might ask the same question in the future).

Is it 60mm? 55mm? I have no idea and need your help.

I'd like to know because I'd like to put in a modern, higher power/wider range speaker into the same slot as I build something usable with the same Snow White industrial design.  

FYI - it is a Mac SE/30 that is beyond economic repair due to exploding Maxell battery surprise. 

Thanks!

I don’t think its that big 50mm maybe. I can’t quite remember i have to open mine to swap out the analog board next week I’ll measure it.
