When designing systems with W7AE drivers, it is very important to achieve a good power match between the subwoofer amplifier and the subwoofer driver's capabilities. The power levels listed in the
above chart represent continuous (RMS) amplifier power per woofer and assume that the user will regularly make full use of that power
without drastically overdriving (clipping) the amplifier(s). Make
sure you factor system impedance and the total number of subwoofers into your calculations. Adhering to these power recommendations will result in systems that are both reliable and enjoyable.

Thank you for purchasing a JLAudio W7AE subwoofer driver. The
W7AE embodies JLAudio’s commitment to pushing the envelope
of speaker technology, with eight patented technologies, a design
patent and a completely unique set of component parts. Each
W7AE model has been meticulously engineered to reproduce
sub-bass with extreme fidelity at any volume level, provided it
is installed and tuned properly. Please review the information in
this document carefully so as to maximize your enjoyment of the
W7AE’s capabilities.
Two enclosure recommendations are listed for each model,
one sealed and one ported. In most cases, the sealed enclosure
design will give you the best overall sound quality and take up the
least space in your vehicle. The ported enclosure design will deliver
additional output over the sealed enclosure (about 3 - 4 dB more)
and will also maintain excellent sound quality, but it will require
significantly more space to install. The recommended ported
enclosure is not designed for peaky “competition SPL” performance,
but rather for music listening. It will be very loud and sound
extremely good when set up properly.
In addition to the enclosure recommendations, we also
provide recommended amplifier settings for JL Audio amplifiers
commonly used with W7AE’s. Some of this information is also
applicable with other brands of amplifiers (like crossover points
and slopes), some is not (like the voltage levels specified for input
sensitivity settings). Please note that W7AE’s rarely require any
equalization to produce smooth frequency response. If you have
an equalizer in your system (or one is included in your head unit
or amplifier), defeat all bands below 125 Hz before dialing in your
new system settings.
For optimum sub-bass performance, the amplifier input
sensitivity must be adjusted to avoid excessive distortion (clipping)
of the amplifier output. Overly high input sensitivity settings
result in no additional clean output but will result in poor sound
quality and reduced speaker reliability. With W7AE subwoofers,
a clipped amplifier output may manifest itself audibly as a low-
level “mechanical” sound coming from the speakers. Proper input
sensitivity setting will avoid this problem.

W7AE Subwoofer Drivers:Tight.
The ultimate no-compromise subwoofer for those seeking extreme output and sublime sound quality.
1 - OverRoll™ Surround
(U.S. Patent #5,687,247 and #5,949,898)
By utilizing space wasted in conventional
speakers, this ground-breaking innovation controls
the W7AE’s massive excursion without sacrificing
precious cone area.
2 - W-Cone™ (U.S. Patent #6,496,590)
The W-Cone™ is a unit-body cone assembly that
delivers astonishing cone stiffness with minimal
mass. The shape also provides incredible torsional
rigidity, which is critical to maintaining voice coil
alignment at the suspension limits.
3 - Floating-Cone™ Attach Method
(U.S. Patent #6,501,844)
Our newly conceived assembly technique ensures
proper surround geometry in the assembled
speaker for better excursion control and dynamic
voice coil alignment. A small detail that means
a lot when you’re pumping the cone to the
excursion extremes the W7AE is capable of.
4 - Plateau-Reinforced Spider Attachment
(U.S. Patent #6,118,884)
A derivative of JLAudio’s famous VRC technology,
this bulletproof suspension attachment relieves
stress from the spider material at high-excursions
for enhanced reliability.
5 - Radially Cross-Drilled Pole Piece
(U.S. Patent #6,243,479)
This innovative venting system greatly enhances
thermal dissipation and power handling by
directing air flow onto the voice coil former,
working in conjunction with technology #6.
6 - Elevated Frame Cooling (U.S. Patent
#D472,891, #6,219,431 and #6,229,902)
The elevated frame design of the W7AE delivers
cool air through slots directly above the top-plate
to the voice coil of the speaker. This not only
enhances power handling, but also sound quality
by minimizing dynamic parameter shifts and
power compression.
In addition to the patented technologies listed above, multiple U.S. and International patents are currently pending.
WARNING:Prolonged exposure to high sound pressure levels can lead to permanent hearing loss.
W7AE subwoofers are capable of reproducing sound at extremely high sound pressure levels. Please exercise restraint in the operation of your system
in order to preserve your hearing and your long-term enjoyment of this product’s sound quality capabilities.
7 - Highly Linear, DMA-Optimized Motor System
DMA is JLAudio’s proprietary Dynamic Motor
Analysis system and is aimed at improving
dynamic motor behavior. As a result of DMA
optimization, W7AE motors remain linear in motor
force over an extreme range of excursion and also
maintain a highly stable fixed magnetic field in
the gap over a wide power range. This leads to
vastly reduced distortion and faithfully reproduced
transients... or put simply: tight, clean, articulate
bass.
8 - Huge Diameter, Progressive-Roll Spider
Arrived at after intense computer analysis and
optimization, the W7AE spiders provide precise
control and motor/voice coil alignment without
prematurely limiting excursion.
9 - Co-Extruded Double Lead-Wires
The extruded casing and carefully engineered
attachments ensure controlled lead-wire behavior
under the most extreme excursion demands. Two
conductors are used per connection for ample
current carrying capability.
10 - Ultra-long Voice Coil
To allow extreme linear excursion, phenomenal
power handling and control, control, control.

W7AE Subwoofer Drivers:Mounting Guide.
The ultimate no-compromise subwoofer for those seeking extreme output and sublime sound quality.
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).
Please review the mounting procedures thoroughly before attempting to remove the speaker
from its shipping baffle. The W7AE mounts like no other speaker and care must be taken to follow
these instructions precisely.
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.
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 W7AE) 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 1: Your Tools
When you remove the W7AE
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 W7AE ever needs to
be shipped back to JLAudio
for service.
Two tools are required to install a
W7AE: a large flat blade screwdriver
and an electric screwdriver with a #2
Phillips-head bit.

Step 6: Connect the speaker wires and
place the W7AE into the enclosure
Connect the positive wire to the red terminal and the negative wire to the
black terminal of the W7AE (picture 6a). The 13W7AE (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 13W7AE.
Step 5: Ready to Install
You are now ready to install the W7AE into its enclosure. The parts are shown below.
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 W7AE
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), 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).
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 frame
(pictures 8a, 8b).
“click”
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 it 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 W7AE!

Remote Level Control
Requires HD-RLC controller
(sold separately). Multiple
ampliers can be controlled
with one controller by
adding standard phone
cable splitter (not included).
This is a true subwoofer level
control, not a “bass boost”.
Input Sensitivity Controls:
Proper adjustment of
these controls is critical!
For virtually all aftermarket
head units, set “Input
Voltage” to “Low”. See
“Input Sensitivity Setting
Guide” on pg. 14 for precise
setting instructions.
JLAudio XD600/1v2:
These settings are intended as a
“baseline” for tuning your system.
Depending on your vehicle and
your preferences, some variation
in the crossover and bass control
settings may be necessary for
optimum performance.
Filter Mode & Slope:
Set “LP Filter Mode/ Slope”
switch to “24dB”. Set “Filter
Freq. (Hz)” knob to “85”.
Lower settings are likely to
result in a poor transition
between the upper
response of the W7AE and
the lower response of the
mid-bass speakers.
Turn-On Mode:
All XDv2 models oer the
convenience of automatic
turn-on (signal or DC-oset
sensing), and a dual-
range input section that
can accept a wide range
of input signals, from
line-level to high-power,
speaker level signals.

Input Sensitivity “Gain” Setting Guide
for JL Audio Subwoofer Amplifiers
Following the directions below will allow you to easily adjust the input sensitivity of the amplifier(s), using commonly
available equipment. Properly setting levels according to this procedure will result in optimum amplifier performance
and improved system reliability.
Step 1:
Disconnect the speaker(s) from the amplifier.
Step 2:
Turn “Off” all processing on the source unit and
the amplifier (bass/treble, loudness, EQ, etc.).
Step 3:
Turn the input sensitivity control on the amplifier
all the way down. If there is a sensitivity range
switch, set it to the “low” position.
Step 4:
Set source unit volume to 3/4 of full volume.
This will allow for reasonable gain overlap
with moderate clipping at full volume.
Step 5:
Cross-reference the amplifier model used and
impedance load per channel on the chart below
to determine the target output voltage.
Step 6:
Verify that you disconnected the speakers before
proceeding. Play a track with an appropriate sine wave
(within the frequency range to be amplified) at 3/4
source unit volume. Selecting the source unit’s “Repeat
Track” feature (if applicable) will be helpful in this step.
Step 7:
Connect the AC voltmeter to the speaker output
of the amplifier.
Step 8:
Increase the input sensitivity control until the desired
voltage (determined in Step 5) is delivered. If multiple
subwoofer amps are being used, set each one to the same
exact voltage and you have also level matched them. On an
amplifier with a sensitivity range switch, if excessive voltage
is read with the control at minimum (full counterclockwise),
switch the “Input Voltage” to “High” and re-adjust.
Step 9:
Once you have adjusted each amp to its maximum
unclipped output level, turn down the volume of the
source unit and turn it off. Reconnect all the speakers,
turn the source unit on and proceed to adjust the
level balance between the subwoofer and satellite
amplifiers. This is accomplished by listening to the
system at a moderate level and turning DOWN the
input sensitivity controls of amplifiers that are playing
too loudly. Do NOT increase the input sensitivity of
any amplifier as this will defeat the purpose of this
procedure by permitting excessive clipping (distortion).
Necessary Equipment
• AC Voltmeter (Digital display recommended)
• A low-frequency (40 or 50 Hz) sine-wave test tone recorded at 0dB reference level.
Do not use attenuated test tones (-10dB, -20dB, etc.).
