Hi Daniel, good morning.
As soon as you switch to Solid Mode, you can see what’s going on; your speaker is too low and hiding under the top Face of the console:

This one:

And that speaker from Side View in Wireframe:

And your screen is also too low, as can be seen even more clearly, if we temporarily Hide the speaker:

First Snap the screen up (G, Z, hold CTRL):

Then Snap the speaker (not just the Inset):

That Face from my second screenshot will stilll be in the way, but that shall be fixed in the Course.
