Installing and Attaching the Woofer
Note:
Do not attach via or puncture the membrane. Do not damage the membrane with a
screwdriver or other sharp tool.
•
After selecting the installation location, attach the installation ring (
C
) at the designated location, e.g.
with double-sided tape, and mark the necessary drill holes and the space for the woofer (inner circle
of the installation ring).
•
Carefully prepare the space for the woofer and drill 2.5 mm holes. Smooth all metal edges, drill holes
carefully, and remove any metal shavings or pieces. As needed, apply a protective varnish or edge
protection.
•
Insert self-tapping nut 3.9 (
I
) into the drill holes.
•
Attach cables according to the instructions (pages
13/14
) and appropriate polarity, and check the
woofer for accuracy of performance functions.
•
Insert installation ring (
C
) and the woofer (
B
) into drill holes in such a manner that the connections
always lie freely. Under no circumstances should these make contact with surrounding metal parts!
•
Carefully attach the woofer with the enclosed self-tapping screws 3.9x32 (
G
) and using the washers
M4 (
H
). Align woofer, ensuring it lies flat, adjust to prevent unevenness through the supporting
rubber edge, and then tighten screws. Make sure that the woofer lies completely flat and may not be
turned by the screws.
•
Insert speaker cover (
A
), from above, perpendicularly into the installation ring (
C
), and firmly press.
