How to break the cab in 2 ? Deep recessed screws tightly bound in dense
plastic. I know , from similar situations, it is quite likely to shear
the
screws with the undoing torque required. Soldering iron heater slid over
the
end of the long shaft screwdriver to locally melt the plastic ? Dropped
power to it for enough heat but relatively low temp to penetrate the
length
of the screw ?

I'm sure I've opened one up no trouble. Take the grille off first.

Take the grill off to change the bass driver but you have to split the whole
case in two to change the horn.
