SEALED ENCLOSURE
Building A Sealed Enclosure:
1.
Build a sealed box with specified dimensions of L x W x D per
drawing. (See chart for suggested box sizes) Use 3/4” thick
material (preferably medium density fiber board or equivalent) for
box construction. Be sure to use wood glue and silicone to ensure
your enclosure is sealed properly, as air leaks will affect the
performance of a subwoofer. (The use of an air stapler will help
to achieve the nicest results for constructing the enclosure.)
2.
Using the supplied template, trace the circle template and
mounting hole pattern for your
PrecisionPower subwoofer on
the appropriate side of the box. (See diagram)
3.
Cut the speaker hole from the face of the box with a router.
Use a guide or template whenever possible for a clean,
accurate job; use a jig saw only if a router is not available.
Drill out the holes for the T-nuts with a 7/32” drill bit.
4.
Place the woofer in the opening which you have cut into the
box to check the fit. Make sure that the T-nut holes line-up.
5.
Install the 10-24 T-nuts (supplied) into the 7/32” holes
from the backside of the face board.
6.
Run an appropriate length of wire into the box, leaving enough
length to comfortably install the wires to the terminals on the
woofer before placing the speaker into its mounting hole. Use
a terminal cup whenever possible.
7.
Vacuum out any shavings and dust that could find it's way into
your woofer from the inside of the box. Fill the box with polyester
fiberfill. Use a ratio of 1/2lb per cubic foot.
8.
Apply the included foam gasket to the speaker to ensure a
sealed fit. Be sure that the mounting holes line up on the
foam gasket.
9.
Connect the wires to the woofer observing the proper polarity,
positive and negative terminals. Strip away the insulation of
the wire about 1/4" and install the wires into the terminal posts.
10.
Install the woofer into the box using the provided 10-24 bolts.
11.
Once the box is completed it is time to connect the speaker
wire coming from the subwoofer enclosure to your amplifier.
Check that you use the proper wire for consistent polarity,
positive and negative. (Refer to amplifier owner’s manual.)
12.
Finally, sit back and enjoy to the incredible enhancement
your new
PrecisionPower subwoofer brings to your audio system.
