Do not use a flathead screwdriver or a hexagonal wrench to

damage the cabinet.
• The midrange and tweeter are integrated into a coaxial
unit. This coaxial-unit speaker is attached to the baffle
board with 6 hexagon-socket screws from the outside.
When disassembling, remove all these screws, pull out
the coaxial-unit speaker, then remove the solder to
disconnect the cords.
When reattaching, connect the cord with black tape to the
tweeter and the cord with white tape to the midrange then
solder the terminals. Place the coaxial unit so that the
terminal board of the midrange comes to the lower side
then turn it counterclockwise slightly to secure it.
