7) There are (6) 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 three-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) Two of the woofer screws are now exposed. Two more are underneath the volume buttons. Remove
the two Faston connectors from the rear of the buttons, then push the buttons out of the front baffle.
This should expose the two remaining woofer screws; 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.

IMPORTANT NOTE
SEE
•
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 three-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.
