SEALED ENCLOSURE
2
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.
Locate the supplied template and with an exacto knife cut through
the correct speaker outline for your woofer, following the printed
lines. Then, 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 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 lineup.
5.
Install 10-24 T-nuts (not 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 wood shavings and dust that could find it's way
into the woofer from the inside of the speaker box. Fill the box with
polyester fiberfill. Use a ratio of 1/2lb per cubic foot.
8.
Apply the foam gasket to the speaker to ensure a sealed fit.
Be sure that the mounting holes line up.
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 10-24 bolts to fit the t-nuts.
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.
