GLA-55 disassembly
Tools needed:
• (2) #8 spanner screwdrivers or #8 spanner bits
• Soldering/desoldering tools
• Phillips
screwdriver
• Torx (size T10) screwdriver or T10 bit
• Exacto
knife
• Optional: One half section of the packing foam
IMPORTANT NOTE:
There a number of pads, gaskets, adhesive, and surfaces with double-sided tape on this
product. Attention must be paid to these areas when the GLA-55 is disassembled. If these
materials are damaged, removed, or disturbed, they must be replaced in their original location,
or the air integrity of the product will be compromised and fidelity may suffer.
I Replacing the Silver-Braided Connecting Cord On The GLA-55 Slave speaker
• Follow steps 1-5 in the procedure below “GLA-55 disassembly Slave speaker (w/ cord)”
II GLA-55 disassembly Left, Slave speaker (w/ cord)
1) Support the loudspeaker with one half section of the packing foam with the base facing upwards.
Alternately, if the packing foam is not available, the speaker must be supported so the base faces
upwards in a clamp so it can be worked on easily, taking care to pad the clamp so the enclosure will not
be scratched.
2) Peel off the four rubber pads on the base cover.
3) Remove the (4) Phillips screws that are now exposed
4) Remove the base cover from the loudspeaker and slide the cord grommet out of the notch
5) Unplug the six pin Molex connector from the small circuit board and set the cord aside.
6) Remove the (3) Torx size T10 screws from the small circuit board
7) There are (4) connections that need to be desoldered (they appear as blobs of solder). Desolder and
remove all excess solder with braided wick or a desoldering tool.
8) Remove the small circuit board; detach and watch for the small, loose “light pipe” that you do not lose it.
9) Remove the (10) Torx size T10 or Phillips screws holding the silver main base on.
10) Remove the single Torx size T10 or Phillips screw (for port tube)

11) Remove the (2) black two-hole grommets by sliding them off the conductors; any adhesive present will
need to be removed with an exacto knife.
12) Remove the silver base.
13) Remove the loudspeaker from the packing foam (or clamp); remove the (5) spanner screws holding the
enclosure together. These screws consist of a spanner head threaded post and screw. WARNING
these are all different lengths, and you should mark of keep track of each screw as they are removed.
14) Separate the two enclosure halves, along with the front faceplate.
15) To access the drivers, pull the front chrome bezel off the front baffle; grasp it by the protective bars over
the tweeter dome and pull outward. The bezel is attached to the front baffle with double-sided tape.
16) The woofer screws are now exposed. Remove as needed.
17) Unplug the Faston connectors and buss wire from the woofer terminals.
18) For the tweeter, remove the black trim surrounding the tweeter dome. It can be pried out of the cavity
using a sharp tool at the relief holes at the top of the trim. Remove the (3) screws as needed. CAUTION
the tweeter screws also hold the port tube in place, remove as needed.
19) Unplug the Faston connectors and buss wire from the tweeter terminals.
20) When replacing the woofer, decorative cover part # 190-0528-001 should be ordered and applied to
the woofer magnet with adhesive.
Re-assembly takes place in reverse order, with these tips:
• SEE
IMPORTANT NOTE
PAGE 1 OF DISASSEMBLY REGARDING GASKETS
• If you have bent the protective bars on the front chrome bezel when removing it, and they will no longer
seat in the three holes, the bars may have to be straightened into the correct position again.
• (2) black two-hole grommets (#29 on the drawing/parts list) will need adhesive added to seat them, and
to seal the buss wires threading through the holes; use silicon sealer or similar adherent.
III GLA-55 disassembly Right, Master speaker (w/amplifier)
1) Support the loudspeaker with one half section of the packing foam with the base facing upwards.
Alternately, if this packing foam is not available, the speaker must be supported so the base faces up in
a clamp so it can be worked on easily, taking care to pad any tools so the enclosure will not be
scratched.
2) Peel off the four rubber pads on the base cover.
3) Remove the (4) Phillips screws that are now exposed
4) Lift the base cover off the enclosure – warning: lift straight up or you may damage a connector.
5) If needed to replace the Main PCB (amplifier) from the base cover, remove the (7) Phillips screws.
6) Remove the (3) Torx size T10 screws from the small circuit board
