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

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!.



Ha! I was just about to come in with exactly the same observation, and you
beat me to it ! Quite a few of these powered speakers follow that general
style of construction, and it's common for something like the self
adhesive
draught excluder foam strip that you fit around door and window frames, to
be used to form an airtight seal between the ally casting and the heavy
plastic case. It's not uncommon for this stuff to stick like a bitch when
it's been clamped up in that joint for a few years. If there genuinely is
just the six screws holding the front to the case, then likely as not, the
answer is just going to be brute force. Is there even the tiniest gap that
you could perhaps get something like a wide wood chisel into to see if you
can spring the plastic away from the metal a little ?

The allied problem (Mackie powered speakers particularly) is long lazy
thread screws jammed into the plastic close to the point of shearing if
undoing them. I made a heated long shaft screwdriver for this, soldering
iron heater slid over the shaft.
