    An Introduction
    Thank you for purchasing a JL Audio W7AE subwoofer driver. The
    W7AE embodies JL Audio’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 lowlevel “mechanical” sound coming from the speakers. Proper input
    sensitivity setting will avoid this problem.

    Please consult the input sensitivity setting information on page 14 of this book.
    RECOMMENDED CONTINUOUS (RMS) POWER RANGE FOR ONE SUBWOOFER DRIVER:
    125W

    250W

    500W

    1000W

    2000W

    4000W

    13W7AE
    12W7AE
    10W7AE
    8W7AE

    GREEN (MINIMUM):
    From a reliability standpoint, this zone
    represents a very comfortable operating
    power range for each driver. This level
    of power will not stress the woofer but
    will not extract all of its performance
    potential, either.
    Use of less than the minimum power
    level will not damage the woofer, but may
    result in unsatisfactory performance.

    YELLOW (OPTIMUM):
    This zone represents the best balance
    between long-term reliability, high
    output and low distortion performance.
    In this zone, you will be taking full
    advantage of the woofer's optimum,
    low-distortion performance range
    without undue risk of failure.

    RED (MAXIMUM):
    In this zone, low-distortion output and
    long-term reliability will be compromised
    (especially by an aggressive user). Slightly
    more SPL will be gained by pushing the
    power into this zone, but typically not
    more than 2dB, compared to the yellow
    zone. The closer you are to the black
    zone, the higher the likelihood of driver
    failure. Operate with caution.

    BLACK (WARRANTY VOID):
    We do not recommend operating
    woofers at this level of power. In this
    zone, there is a very high probability that
    the driver will fail due to excessive heat
    and/or mechanical stress.
    Subwoofer drivers operated at
    these levels of power are NOT covered
    under warranty.

    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.

    W7AE Subwoofer Drivers: Tight.

    The ultimate no-compromise subwoofer for those seeking extreme output and sublime sound quality.

    1-O
     verRoll™ 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.

    4 - Plateau-Reinforced Spider Attachment
    (U.S. Patent #6,118,884)
    A derivative of JL Audio’s famous VRC technology,
    this bulletproof suspension attachment relieves
    stress from the spider material at high-excursions
    for enhanced reliability.

    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.

    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.

    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.

    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.

    7-H
     ighly Linear, DMA-Optimized Motor System
    DMA is JL Audio’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-H
     uge 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 - U
     ltra-long Voice Coil
    To allow extreme linear excursion, phenomenal
    power handling and control, control, control.

    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.

    W7AE Subwoofer Drivers: Mounting Guide.

    The ultimate no-compromise subwoofer for those seeking extreme output and sublime sound quality.
    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 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 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
    W7AE: a large flat blade screwdriver
    and an electric screwdriver with a #2
    Phillips-head bit.

    O-Ring up and off the speaker with your
    fingertips and set it aside.

    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 5: Ready to Install

    You are now ready to install the W7AE into its enclosure. The parts are shown below.

    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 7: Screw it in (12 times)

    Line up the screw holes of the frame
    with the holes that you have predrilled 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).

    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 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.

    9b

    9d

    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.

    13W7AE Subwoofer: Amplifier Recommendation.
    HD1200/1 (shown) or 1200/1v3

    JL Audio HD1200/1:

    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 “Mode” switch to
    “LP”. Set “Slope” switch to
    “24dB”. Set “Filter Freq.
    (Hz)” knob to “85”.
    Lower settings are likely to
    result in a p
     oor transition
    between the upper
    response of the W7AE and
    the lower response of the
    mid-bass speakers.

    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.

    Remote Level Control
    Requires HD-RLC controller (sold separately).
    Multiple amplifiers 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”.

    Output Polarity:
    Carefully listen to the sub-bass to mid-bass transition with music
    that h
     as strong mid-bass content. Select the switch position
    which gives the smoothest, most natural mid-bass response. If
    using multiple HD1200/1’s on multiple subwoofers, make sure
    this switch is set to the same position o
     n all amplifiers.
    Infrasonic Filter:
    Turn “Off” for Sealed Enclosure.
    Select “30Hz” for Ported Enclosure.

    JL Audio 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 p
     oor transition
    between the upper
    response of the W7AE and
    the lower response of the
    mid-bass speakers.

    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.

    Remote Level Control
    Requires HD-RLC controller
    (sold separately). Multiple
    amplifiers 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”.

    Turn-On Mode:
    All XDv2 models offer the
    convenience of automatic
    turn-on (signal or DC-offset
    sensing), and a dualrange 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.
    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.).

    The Nine-Step Procedure:
    Step 1:
    Disconnect the speaker(s) from the amplifier.
    Step 2:
    T urn “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 and­turning 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).
