speaker. This vent is located around the JL Audio badge at the rear of the speaker. A 
minimum distance of 3/4-inch (20mm) is required between the back of the speaker 
and any wall of the enclosure to allow proper operation of the pole vent.

external

 dimensions which assume the 

use of 

3/4" (19mm)

 thick material. If you are using 

5/8" (16mm)

 thick material, subtract 

1/4" (6.5mm) 

from each dimension. Do not use any material with a thickness of less 

than 

5/8" (16mm)

 as this may compromise the rigidity of the enclosure.

All enclosure volumes listed are net internal volumes!

 Box volume displacement, 

port displacement and brace displacement must be added to obtain the final gross 
internal volume. All enclosure dimensions listed have already taken this into account.

s7HEN USING

two

 subwoofers in a common enclosure simply 

double

 the 

 

required volume and, in the case of a ported enclosure, use 

two times

 the 

recommended port(s).

s7E RECOMMEND THE USE OF THIS SPEAKER IN A

bi-amplified system

 using high-

quality satellite speakers and amplifiers.  We do not recommend the use of this 
subwoofer with a 

passive crossover (coil)

, as this type of device will adversely 

affect performance.

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

no correction factors applied.

 **  Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output 

capability and should not be used as a comparison to other subwoofers to 
determine which one is “louder” !   

***  Re (DC resistance) is measured with the voice coils in series, for parallel-

wired specification divide Re by 4. All other specifications remain the same. 

SUBWOOFER SPECIFICATIONS

RECOMMENDED ENCLOSURES

Prolonged exposure to sound 

pressure levels in excess of 100dB can 
cause permanent hearing loss.  This high-
performance speaker can exceed this level. 
Please exercise restraint in its operation 
in order to preserve your ability to enjoy  
its fidelity.

When installing a subwoofer in your 

vehicle, it is extremely important to secure 
the enclosure firmly.  We recommend 
bolting the enclosure through the metal of  
the floorpan or the frame of the 
vehicle with large diameter washers for 
reinforcement. If an enclosure is not firmly 
attached, it can become a projectile in a 
collision. This is particularly important in 
a hatchback, station wagon, sports utility 
vehicle, or van.
