Owner’s Manual

An Introduction

Thank you for purchasing a JL Audio W7 subwoofer driver. The W7 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 W7 model has been meticulously engineered to reproduce sub-basswith 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 W7’s capabilities.

 

Two enclosure recommendations are listed for

each model,

one sealed and one ported. The sealed enclosure

design will,

in most cases, 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, it is designed 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 used with W7’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). You will notice that our recommended settings do not include any bass EQ boost... this is because W7’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. Please turn off all sound processing that would affect the subwoofers (loudness circuits for example).

For optimum sub-bassperformance, the amplifier input sensitivitymust be adjusted to avoid excessive distortion (clipping) of the amplifier output. With W7 subwoofers, a clipped amplifier output will manifest itself audibly as alow-level“mechanical”sound coming from the speakers. Proper input sensitivity setting will avoid this problem. Overly high input sensitivity settings result in no additional clean output but will result in poor sound quality and reduced speaker reliability.

Please consult the input sensitivity setting information on page 14 of this book.

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-termreliability, high output and low distortion performance. In this zone, you will be taking full advantage of the woofer's optimum,low-distortionperformance range without undue risk of failure.

RED (MAXIMUM):

In this zone, low-distortionoutput andlong-termreliabilitywillbecompromised(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 W7 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.

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.

1

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.

Two tools are required to install a W7: a large flat blade screwdriver and an electric screwdriver with a #2 Phillipshead bit.

Wrong

Step 2: Remove Clamp-Ring

Gently insert the tip of the large flat-headscrewdriver between the shiny aluminumclamp-ringand the foam surround (picture 2a). Be careful not to push the screwdriver too far down or it will wedge behind the hiddenO-Ring(picture 2b). Gently twist the screwdriver to “pop” theclamp-ringoff of theO-Ringand 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 theO-Ring.Once you have released the tip of theclamp-ring,a gentle push with your thumb in the direction of the speaker circumference (picture 2d) will separate theclamp-ringfully (picture 2f). Donot pull up on the ring until it is completely removed (picture 2g).

Step 3: Remove O-Ring

Step 4: Remove Screws

Once the O-Ringis 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 4f 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

Step 6: Connect the speaker wires and

shown below.

 

place the W7 into the enclosure

 

Connect the positive wire to the red terminal and the negative wire to

6a

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.

 

6b

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-drillthe 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

7a

do it. While holding the surround

back with two fingers (picture 7a),

 

screw the speaker into the enclosure

7b

(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).

8a

7c

Step 8: Attach O-Ring

Next, take the steel O-Ringthat you removed in step 3, and place it over the outside of the surround. Push it down evenly (donot seat one side first) to make sure it seats the lower lip of the surround down to the

frame (pictures 8a, 8b).

9a

8b

 

Be sure that the beveled edge of theclamp-ringis “pointing” towards the front of the speaker. Theclamp-ringis only designed to work in this orientation.

“click”

9b

Step 9: Attach Clamp-Ring

Place the seam of the clamp-ringwhere it will be

least visible in the installation (usually at the bottom

9c

of the speaker). Start one end of the clamp-ringby pressing

i t

in firmly (pictures 9a, 9b). Then work your way around from that point around the speaker, pushing the clamp-ringinward 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!

Amplifier Recommendation: 1000/1v2

JL Audio 1000/1v2:

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.

Bass EQ:

Generally not necessary in W7 applications (we recommend defeating it by switching the “Bass EQ” switch to “Off”). May be used with Remote Bass Control to provide some user controllable broad bass boost. When used in this manner, set “Q” to “1.1”, set “Center Freq.” to “45” Hz, “Boost” is defeated by connection of Remote Bass Control.

Remote Bass Port:

Permits connection of an optional remote bass boost controller (RBC-1),giving you control over the boost of the parametric EQ from the front of the vehicle. TheRBC-1controller is sold separately.

Amp Low-PassFilter:

Set “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 W7 and the lower response of the mid-bassspeakers.

Ampli er Input:

Connect RCA-typecables from the head unit (or processor) to these two jacks.

Use both jacks (with a Y-adapterif necessary).

Output Polarity:

Carefully listen to the sub-basstomid-basstransition with music that has strongmid-basscontent. Select the switch position which gives the smoothest, most naturalmid-bassresponse. If using multiple 1000/1’s on multiple subwoofers, make sure this switch is set to the same position on all ampli ers.

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.

The dimensions given for the enclosure examples below take all applicable displacements into consideration.

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.
