This product appears to be the pro-audio equivalent of most remote
controls.

I'm sure most people in this group have noticed how remote controls are
generally held together with screws /and/ near-unreleasable tabs. I've
never
understood why both are needed.



No, it's not, and you're misunderstanding the packaging here.

There's a diecast metal front panel which covers the entire front of the
unit, with a deeply set grille for the speaker. Six screws attach the
metal panel to the plastic cabinet.

The plastic cabinet is ONE PIECE, totally seamless, covering the
remaining 5 sides. So it's not a clamshell like most remotes or similarly
packaged electronics.


it most likely has a sealant between the front and plastic case to
prevent vibration at the seem, which is common with that type of
construction.. These things will stick like mild glue..

With the screws half way, wrap the unit in a soft wrap of some kind
like foam rubber so you don't scratch it, rest it on a pillow and use
something like a piece of wood to hit lightly against the screws that are
half way out.. The shock should push on the plastic behind and break
the bond!.

Yes.....Even if you were to crack the plastic, cracked plastic is a fairly
easy thing to fix, and/or live with. Consider cutting a large hole in the
back, which can later be covered with a glued- on piece of plastic, and used
as an inspection/access hole in the interim. ( I belong to the, "get a
bigger hammer" school of maintenance....:^)
