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.
