Free Air Resonance (Fs): 27.2 Hz

Electrical “Q” (Qes): 0.514

Mechanical “Q” (Qms): 7.807

Total Speaker “Q” (Qts): 0.482

Equivalent Compliance (Vas): 2.33 cu. ft. (66.0 ltrs)

One-Way, Linear Excursion (Xmax)*: 1.15 in. (29 mm)

Thermal Power Handling (Pt): 1000 Watts Continuous

Reference Efficiency (no): 0.249 %

Nominal Impedance (Znom): 3Ω

* Xmax specifications are derived via one-way voice coil overhang method with

no correction factors applied.

Infrasonic Filter:

Turn “O” for Sealed Enclosure.

Turn “On” for Ported Enclosure and

set the knob to “25” Hz.

Bass EQ:

Generally not necessary in W7 applications (we recommend defeating it by

switching the “Bass EQ” switch to “O”). 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.

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.

Dual Mono Speaker

Output Connections:

Connect wire directly to “+”

and “–” “Subwoofer Output”

connections and to the W7.

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. The RBC-1

controller is sold separately.

Amp Low-Pass Filter:

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-bass speakers.

Amplier Input:

Connect RCA-type

cables from the head

unit (or processor) to

these two jacks.

Use both jacks

(with a Y-adapter

if necessary).

Output Polarity:

Carefully listen to the sub-bass to

mid-bass transition with music that

has strong mid-bass content. Select

the switch position which gives the

smoothest, most natural mid-bass

response. If using multiple 1000/1’s

on multiple subwoofers, make sure

this switch is set to the same position

on all ampliers.

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. (See settings

on page 10 for 500/1.)

RECOMMENDED CONTINUOUS RMS POWER RANGE FOR ONE SUBWOOFER DRIVER:

500W 750W 1000W 2000W 4000W250W

Amplifier Recommendation: 1000/1v2 (pictured), HD750/1,

500/1v2 or G-MAX
