Where are the speakers mounted in real fruit machines?

Hi all,

I'm going to build an MFME cabinet and wondered where to put the speakers. When I built my MAME arcade cab I put them at the top behind some audio cloth but I'm thinking of just leaving them inside the machine next to the monitor on my MFME build.

But I wondered if real fruitys have speakers in the bottom of the cabinet or if they are just built into the middle behind the top glass or what?

Anyone know?

Thanks for any info you have on this. :-)
