W7 Mounting Guide
Please review the mounting procedures thoroughly before attempting to remove the
speaker from its shipping baffle. The W7 mounts like no other speaker and care must be
taken to follow these instructions precisely.

Step 1: Your Tools
When you remove the W7 from
its shipping carton, it is attached
to an MDf baffle board. Make
sure you keep this baffle board
and all the packing material
in the unlikely event that the W7
ever needs to be shipped back to
JL Audio for service.

Step 2: Remove clamp-Ring
Gently insert the tip of the large flat-head screwdriver between the shiny aluminum clamp-ring
and the foam surround (picture 2a). Be careful not to push the screwdriver too far down or it
will wedge behind the hidden O-Ring (picture 2b). Gently twist the screwdriver to “pop” the
clamp-ring off of the O-Ring and frame (picture 2c). This should require little effort... if you are
encountering high resistance, pull the screwdriver up a bit to make sure it is not wedged behind
the O-Ring. Once you have released the tip of the clamp-ring, a gentle push with your thumb
in the direction of the speaker circumference (picture 2d) will separate the clamp-ring fully
(picture 2f). Do not pull up on the ring until it is completely removed (picture 2g).
Two tools are required to install a W7:
a large flat blade screwdriver and an
electric screwdriver with a #2 Phillips-
head bit.

Step 3: Remove O-Ring

Once the clamp-ring is removed, the
steel O-Ring is exposed. Gently lift this
O-Ring up and off the speaker with
your fingertips and set it aside.

4e
Step 4: Remove Screws
Once the O-Ring is out of the way, the surround is completely
free of the speaker frame (no glue is used to secure it). Lift the surround
up and fold it back inside the speaker frame (picture 4a). This exposes the
mounting screws (picture 4b). The surround should be folded back and in
towards the center of the speaker (picture 4c). Do not pull it up (picture 4d)
or invert it (picture 4e). While holding the surround back with two fingers
as shown, back the first screw out using your electric screwdriver
(picture 4f, 4g). Repeat this process eleven more times (there are
twelve screws on a W7) until you have separated the speaker
from the shipping baffle-board. Before you panic, be aware
that the surround and cone materials are rugged and will
not be damaged if you follow the procedures shown. Only
careless acts like picking the speaker up by the surround or
creasing it by force will cause permanent damage.

Step 5: Ready to Install
You are now ready to install the
W7 into its enclosure. The parts are
shown below.
Step 6: connect the speaker wires and
place the W7 into the enclosure
connect the positive wire to the red terminal and the negative wire to
the black terminal of the W7 (picture 6a). The 13W7 (not shown) has dual
voice coils and must be wired with its coils in series or in parallel. Once
the speaker is wired, gently lower it into the enclosure (picture 6b). This is
difficult on a vertical mounting surface (because of the speaker’s
weight) so you should enlist the help of a second person. If you
need a better grip (or are afraid of smashing your fingers)
you can grasp the inside of the speaker’s mounting flange
(remember, the surround moves out of the way). This tip
is particularly useful with the 13W7.
6a

Step 7: Screw it in (12 times)
Line up the screw holes of the frame
with the holes that you have pre-
drilled in your enclosure (you did
pre-drill the holes, right?). The W7
should be attached with heavy
screws such as the ones supplied with
the speaker. This will necessitate pre-
drilling. The use of inferior hardware
(i.e. drywall screws) may lead to
disastrous consequences, so don’t
do it. While holding the surround
back with two fingers (picture 7a),
7a
screw the speaker into the enclosure
(picture 7b). Once all twelve screws
are in place (you did use all twelve,
right?), place the surround back over
the outside of the speaker frame
(picture 7c).
7b
8a
Step 8: Attach O-Ring
Next, take the steel O-Ring that you
removed in step 3, and place it over
the outside of the surround. Push it
down evenly (do not seat one side
first)to make sure it seats the lower
lip of the surround down to the
7c
9a
frame (pictures 8a, 8b).

Be sure that the beveled edge of
the clamp-ring is “pointing” towards the front of the
speaker. The clamp-ring is only designed to work in
this orientation.

Step 9: Attach clamp-Ring
Place the seam of the clamp-ring where it will be
least visible in the installation (usually at the bottom
of the speaker). Start one end of the clamp-ring by pressing
9c
i t
in firmly (pictures 9a, 9b). Then work your way around from that point
around the speaker, pushing the clamp-ring inward and in the direction
of the circumference of the frame (pictures 9c, 9d). If you have achieved a
tight fit all around, the seam will be small when you reach the starting point
again (pictures 9e, 9f). check the entire circumference for a tight fit just
to be sure.
That’s it!
You’ve just installed a W7!

poor transition between the upper
response of the W7 and the lower
response of the mid-bass speakers.
Connect RCA-type cables from
the head unit (or processor) to
these two jacks. Use both jacks
(with a Y-adapter if necessary).

Enclosure Specifications
Net volumes given below do not include the air volume displaced by
the speaker (Driver Displacement). This value must be added to the
net volume along with the displacement of any braces and/or ports (if
applicable) to arrive at a gross internal volume. Air inside a port is not part
of the effective net volume. Calculate ports as solid, not hollow objects.
SAfETY NOTIcE!
It is absolutely essential that the completed subwoofer enclosure is mounted
firmly to the vehicle with heavy steel bolts (1/2 inch diameter) and large steel
washers on both sides of the bolts. This will reduce the likelihood of occupant
injury in the event of a collision or sudden deceleration.
The dimensions given for the enclosure examples below take all applicable
displacements into consideration.

Input Sensitivity Setting Guide
What follows is a simple method for accurately setting the
input sensitivity (commonly referred to as “gain”) of JL Audio
subwoofer amplifiers. You will need the following equipment:
• AC Voltmeter (digital display type)
• A CD with a sine-wave test tone recorded at
0dB reference level in the frequency range to be
amplified (40-50 Hz works well).
Do not use attenuated test tones
(-10dB, -20dB, etc.).
Step 6: Connect the AC voltmeter to the “Subwoofer Output”
of the amplifier.
Step 7: Consult “Appendix A” in your JL Audio amplifier’s
Owner’s Manual and find the correct target
output voltage for that model and the nominal
impedance of your W7 subwoofer setup.
If you are using another brand of amplifier, we
recommend that you use an oscilloscope to verify the
maximum unclipped output in the vehicle at realistic
vehicle supply voltages.
Step 1: Disconnect the W7(s) from the amplifier
(It is only necessary to disconnect one wire).
Step 2: Turn “Off” all processing on the head unit and amplifier
(bass / treble, loudness, EQ, etc.)
Step 8: Increase the “Input Sensitivity”control (clockwise) until the
listed voltage is delivered. To level-match multiple subwoofer
amps, set each one to the listed voltage. If excessive voltage
is read with the control at minimum (full counter-clockwise),
switch the “Input Voltage”to “High”and re-adjust.
Step 3: Switch “Input Voltage”to “Low”and turn the
“Input Sensitivity”control on the amplifier
all the way down (full counter-clockwise).
Step 9: Reduce the head unit’s volume and turn it off.
Reconnect the subwoofers to the amplifier.
Step 4: Verify that you have disconnected the subwoofers from the
amplifier. Then, set the head unit’s volume to 3/4 of full volume.
Step 5: Play a test track with a sine-wave (pure tone)
between 40-50 Hz.
