To rotate the horn moulding from ‘B’ mode to ‘A’ mode

Lift the horn assembly part-way out of the cabinet as above and rotate it back so that the high frequency horn is now orientated towards the long edge of the cabinet. Lower it carefully back into the cabinet ensuring that the connecting cables do not snag.

Rest the horn assembly on the cabinet edge (a piece of cardboard will help to avoid damaging the woodwork) and disconnect the wires to the high frequency drivers and the high-mid drivers, taking note of the polarity. Place the horn assembly face down on a work bench if it is necessary to repair or replace drive units or diaphragms.

Removal of the high frequency driver

Using an M4 Allen key undo the M5 socket head screws holding the high frequency magnet assemblies in place and carefully lift the magnet assembly away from the rear of the horn.
