SEALED ENCLOSURE
Building A Sealed Enclosure:
1.
Build a sealed enclosure with internal L x W x D as specified for
your woofer (See page 10). Use 1” thick MDF (medium density
fiber board) for the baffle that the Subwoofer mounts in, and 3/4”
thick MDF for the rest of the enclosure. Be sure to use wood glue
and silicone to ensure your enclosure is sealed properly, as air
leaks will affect the performance of your subwoofer.
2.
Using the supplied template, trace the appropriate circle and
mounting hole pattern for your
PrecisionPower subwoofer on
the baffle board. (See diagram)
3.
Cut the speaker hole from the baffle board 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 in the
baffle to check the fit. Make sure that the T-nut holes line-up.
5.
Install the 10-32 T-nuts (supplied) into the 7/32” holes
from the backside of the baffle board.
6.
Run an appropriate length of wire into the enclosure, 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 from the inside of the
enclosure. (Failure to do so may void your warranty.) Loosely
fill the box half way with polyester fiberfill.
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 enclosure using the 10-32 bolts
(supplied).
11.
Once the enclosure is complete, 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 the incredible enhancement your
new
PrecisionPower subwoofer brings to your audio system.
