For better audio quality, the receptacle terminals and terminal fittings of the speaker unit are soldered.
Two people are required for servicing of this speaker unit: one to hold the removed unit and another to
solder.
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 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.
•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.

(6) Apply adhesive to the secured nuts.
(Adhesive: DIABOND black/GYL-014)
(7) Reinstall the acoustic absorbent pads at the input
terminals. (See Figs. 2-5 to 2-8.)
(8) Among the 3 pairs of cords from the Network Assy,
connect and solder the remaining 2 pairs of cords
with white tape to the woofer and reattach the woofer
in the cabinet.
2.3.2 Network Assy for the midrange /
tweeter
•The Network Assy for the midrange/tweeter is attached to
the inside of the left side board behind the upper woofer,
using 4 screws.
(1) Remove the acoustic absorbent pads at the input
terminals, inside and at the rear of the chamber, and
behind the chamber.
(See Figs. 2-5 to 2-8 and 2-9 to 2-11.)
(2) Remove the 2 nuts that secure the round connectors
from the upper input terminals.
(See Fig. 2-1. Tool: Box wrench, 14 mm/GGH-002)
(3) Remove the 4 screws that secure the closure panel
inside the chamber, remove the 4 screws that secure
the Network Assy, and pull the Network Assy out
through the hole where the woofer was attached.
(See Figs. 2-3 and 2-4. Tool: Screwdriver/GGK1012)
(4) When reattaching, pass the Network Assy through the
hole where the upper woofer was attached and secure
it in place using the 4 screws.
(See Fig. 2-3. Tool: Screwdriver/GGK1012)
(5) Among the cords from the Network Assy, connect the
cords with the round connectors to the upper input
terminals and secure them with the nuts.
(See Fig. 2-1. Tool: Box wrench, 14 mm/GGH-002)
(6) Apply adhesive to the secured nuts.
(Adhesive: DIABOND black/GYL-014)
(7) Pass the 2 pairs of cords from the closure panel
through behind the chamber then secure the closure
panel from inside the chamber, using the 4 screws.
(See Fig. 2-4.)
(8) Reinstall the acoustic absorbent pads at the input
terminals, inside and rear of the chamber, and behind
the chamber.
(See Figs. 2-5 to 2-8 and 2-9 to 2-11.)
(9) Connect and solder the cords to the coaxial-unit
speaker and reattach it in the cabinet.

2.3.3 Removal/Reattachment of Acoustic absorbent pads
Note:
When reattaching the Network Assy for the midrange/tweeter, before reattaching the closure panel, be sure to remove the
acoustic absorbent pads located behind the chamber. (See Fig. 2-11.) If the closure panel pinches an acoustic absorbent
pad when it is secured, air leakage may occur, which may result in poor performance of this speaker system.
Removal/reattachment of acoustic absorbent pads is necessary before or after removal/reattachment of the Network Assy.
1. Acoustic absorbent pads around the input terminals 2. Acoustic absorbent pads inside the chamber for
the midrange/tweeter
3. Acoustic absorbent pads around the Network Assy
for the midrange/tweeter

3Remove this acoustic
absorbent pad.
When reattaching, fold it in
half lengthwise and push it
in.
1Remove this acoustic absorbent
pad. When reattaching, roll it
and push it in under the rein-
forcing plate.
As only this acoustic absorbent
pad must be fixed with adhesive,
before pushing it in, apply
adhesive to the side board of the
cabinet.
1Remove this acoustic absorbent pad.
When reattaching, lay it along the
upper board inside the chamber.
2Remove this acoustic absorbent pad
When reattaching, place it along the
surface inside the chamber so that it
forms a U shape.
3Remove this acoustic absorbent
pad from the closure panel section.
When reattaching, fold it in half
lengthwise and push it in.
4Do not remove the acoustic
absorbent pads around the Network
Assy for midrange/tweeter.
Remove the 2 rolled acoustic
absorbent pads stuffed behind the
space of the chamber for midrange
/tweeter.
Insert your hand in the direction of
the arrow to remove.
Removal/reattachment of the
Network Assy for the midrange/
tweeter and of the closure panel
must be done in this state.
2Remove this acoustic absorbent
pad. When reattaching, push it
in along the lower surface of the
reinforcing plate.
Fold the remaining part of the
pad toward the bottom board
side so that it forms an L shape.
The cords from the input
terminals must be pulled out
from the upper side of the
acoustic absorbent pad.
(Adhesive: DIABOND black/GYL-014)
In this state, remove or
reattach the Network Assy.
When reattaching, lay one acoustic absorbent pad on another and
roll them, and make 2 rolls of acoustic absorbent pads.
Place one roll lengthwise, push it into the front of the top board
of the cabinet, then push another beneath of the first one.
