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 template at the designated location, e.g. with
double-sided tape, amd mark the necessary drill holes and the space for the woofer.
•
For the attachment of the woofers in wood or plastic the included torque screws 4.0 x 30 (G), which require
∅
3.2 mm drill holes, should be used
•
For the attachment of the woofers in doorboards, where an additional steel ring can be inserted underneath, the
included head cap screws M4 (C), which require drill holes of
∅
4.2 mm, should be used. The head cap screws
can alternatively, depending upon accesibility, be bolted with the included self-locking nuts M4 (E) or high-
grade steel nuts M4 (D).
•
Prepare the space for the woofer by smoothing all metal edges and drill holes carefully, removing any metal
shavings or pieces. As needed, apply a protective varnish or edge protection.
•
Attach cables according to the instructions (page 9-13) and appropriate polarity, and check the woofer for
accuracy of performance functionality.
•
Insert woofer (B) into the space and fasten into drill holes in such a manner that the connections always lie
freely. Under no circumstances should these make contact with surrounding metal parts!
•
Loosely attach the woofer with the selected screws and washers M4 (H). Align woofer, ensuring it lies evenly
flat, adjust as necessary through the rubber support, and tighten screws. The woofer must lie absolutely flat and
should not be able to be turned when adjusting screws.
•
From overhead, insert speaker grill (A) together with the enclosed rubber ring perpendicularly into the inner
ring of the woofer and press.
