Question

Hi there! Is it normal that the Presonus Eris E5 gets a bit hot in the back?

Answer 1

Yes this is normal! They're powered monitors so the amps makes them hot. Since there's no external heat sink it's also normal that it can be hotter than some other powered speakers. They should not be hot to a point where you would be scared of leaving them on all the time. If you are concerned with heat, you can power them off after each use.
