Roland cube , tweeter over the 10 inch bass unit. Stands on what seems to be
a plastic stem passing through the bass cone, wires to it passing through
that cone also. How to remove the tweeter section to get to ,hopefully,
failing wiring joint that is normally covered by the dome of a single normal
speaker. There is a square recess in that stem, a "Frenchman" to break a
plastic weld joint ? no fixings proper seen anywhere.
