For better audio quality, the receptacle terminals and terminal fittings of the speaker unit are soldered. 
When disassembling/reassembling the speaker unit, be sure to refer to the following figures.

Piece of soft cloth

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 around 
the edge of the hole where the woofer was attached, to 
protect the cabinet from being scratched.

When working on the coaxial-unit speaker

Provide a stand with a height of approx. 15 cm and a piece
of soft cloth for protection. Place the coaxial-unit speaker 
on the cloth. 
To work on the coaxial unit, drape a piece of soft cloth 
around the edge of the hole where the coaxial-unit speaker
was attached, 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.
