- Enclosure Construction & Assembly -
This was the fun part. I knew that since I was going to
have two different thicknesses of boards on the front
of each speaker, I needed to cut the holes using my
newly ordered Jasper circle jig (#365-250) prior to the
overall box construction. I spent about 4 hours taking
measurements, drawing sketches, and taking remeasurements
to make sure I got the fronts right the
fi rst time. I fi rst routed all the wood board edges with
a 1/8" roundover bit and then I glued the alternating wood pattern on the front piece of MDF. I made
sure to cover the entire back of the wood boards to
eliminate any vibrations (I used a total of 5 full tubes
of liquid nails throughout the project). After the glue
dried, I routed the recess depths for the drivers to be
housed and then the actual holes. I cut the holes for
the tweeters with a hole saw. After this step, I was
able to assemble the actual box and continue gluing
the alternating board pattern. The boards around the
edges are 1/2" thick instead of the 1/4" boards that
were used on the face, sides, and top. This allowed
me to route a 45° bevel and provide a little depth that
gives it an almost picture frame appearance. Then
I continued gluing the boards to the sides and top. I
sealed all the inside joints with caulk and placed bits
of cut foam in it for dampening. The only thing left was
to apply 5 coats of polyurethane, screw on the rubber
feet, and install the crossover and drivers. To add a
fi nishing touch, I used the ring portion of the steel
mesh grill to cover the 10" woofer gasket.
