Tools to be used
• Hexagonal wrench (4 mm): GGK1024
• Soldering gun: GGK1069
• Lead-free solder: GYP1006
• The woofer is attached to the baffle board with 6
hexagon-socket screws from the outside.
When disassembling, remove all these screws, pull out the
woofer, then remove the solder to disconnect the cords.
When working on the woofer
Provide a stand with a height of approx. 15 cm and a piece
of soft cloth for protection. Place the woofer on the cloth.
To work on the woofer, drape a piece of soft cloth from
around the edge of the hole where the woofer was attached
to the duct, to protect the cabinet from being scratched.
When working on the coaxial-unit speaker
Drape a piece of soft cloth on the top board and place
the coaxial unit on the cloth, to protect the cabinet from
being scratched.
• 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, after connecting the cords, solder the
terminals for the woofer then place the woofer so that the
terminal board comes to the lower side. 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.
