First order of business was to get a wire
harness together with a 12 volt power supply that would
allow the speaker to be deployed with the flick of a
switch!

In these images you can see the warp in the speaker
housing.
Some people would just live with this, but the
crooked lines would bother me every time I looked at them
and I just had to improve the situation.

is a closeup of the warp!

I
decided that I could use some flat head screws to suck the
warped edges in towards the speaker baffle by drilling a
countersunk hole through the speaker can and the speaker
baffle. Installing
6-32
flat head screws and carefully torquing them in order to
bring the speaker can into alignment with clearance
between the bezel.
Here you can see the Solid Works
model of the mock up speaker can and the speaker baffle as
well as the drilling fixture installed on the speaker can.

Actual pictures of the drill guide installed on
the speaker can. You can see how it keys onto the flange
around the edge of the speaker can. I used a wide rubber
band with hooks on both ends to hold the drill guide in
place while drilling the holes.

I
originally planned on using actual 3/16 OD x .1065 drill
guides but the $13.00 + price tag x 9pcs led me to 3d
printing some drill guides in SLS Nylon. I made 3
different types and ended up using the shorter bushings
with straight sidewalls as they fit the FDM Drill template
well and provided ample clearance between the speaker can
and the drill bushing allowing the chips to accumulate
inside the drill guide holes when drilling.
You can
see the SLS 3d printed basket that contained the arrayed
drill bushings in several layers inside the basket keeping
them all together to ease post build processing (cleaning
the un- sintered powder off the sintered parts) .
You can also see the 3 different
types of bushings I printed: short, long, and long with
relieved sides (in case they were a really tight fit in
the drill guide).

And last but not least here are the
modified speakers and you can see that the appearance is
greatly improved as most of the warp is gone.

In these pictures ou can see the addition of
the 9 screws that are used to remove the warp in te
speaker can.
I may either paint the screws or find some
vinyl adhesive discs in the same color as the speaker
plastic to cover them up.

Here are some extra images of the
back side of the grill and the back of the motorized
speaker from different angles.
