The

subwoofers incorporate a 2” voice coil while the

onto black anodized aluminum formers and are available in both 4Ω and 8Ω
versions. The voice coils are cooled and given increased mechanical
damping through the use of a ferrofluid filled magnetic gap. The cooling,
and therefore power handling, is further enhanced by the extended pole
piece and vented magnet cavity. The long field motor structure results in a
substantial reduction of distortion over conventional loudspeaker systems.
Increased linearity at large excursion is obtained by using dual matched
rear suspension components together with the finest quality poly-foam
surround.
The most unique feature is the use of a flat diaphragm instead of a conical
structure. The diaphragm is constructed from a combination of state of the
art materials which include E-Glass and Nomex honeycomb. The result is a
diaphragm that is exceptionally stiff and lightweight which does not exhibit
cone flex distortion or the buckling effects inherent in conventional designs.
Additionally ,

PrecisionPower

chose a high grade steel basket design to
complement the demands of this rugged driver.
Included in this manual are a number of sample enclosure drawings. They
are by no means the only enclosures to use, but rather a starting point in the
right direction. To determine the correct enclosure for your needs many
factors need to be addressed (amount of power, vehicle, placement,
crossover, etc.) Therefore, as always,

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 af fect 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

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.

subwoofer on the appropriate side of the

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

PORTED ENCLOSURE

Building A PPI Ported Enclosure:

1. Build a sealed box with internal dimensions of LxWxD as specified for
your woofer. 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 appropriate circle and mounting hole pattern for your

PrecisionPower

woofer. Be sure to offset the woofer to one side to allow for the port to
fit comfortably.(See diagram)

3. Cut the speaker hole out 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 mounting holes with a 7/32” drill
bit.

4. Locate the port material which you are going to use. Trace the pattern
of the appropriate hole needed for the port, then cut the hole out. When
installing the port, make sure you have a distance of at least the
diameter of the port from the end of the port to the wall inside the box.
To best seal off any air leaks use silicone around the inside edge. Also,
bevel the inside edge of both ends of the port to cut down on port noise.

5. Place the woofer into the hole which you have cut into the box to check
the fit. Make sure that the T-nut holes line up.

6. Install 10-24 T-nuts (not supplied) into the 7/32” holes from the
backside of the mounting board.

7. 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.

8. Vacuum out any wood shavings and dust that could find it's way into
the speaker from the inside of the speaker box. Line the box with a
polyester fiberfill blanket or fiberglass insulation about 1” thick.

9. Apply the foam gasket to the speaker to ensure a sealed fit.
Be sure that the mounting holes line up.

10. 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.

11. Install the woofer into the box using the provided 10-24 bolts.

12. 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.
