SPECIFICATIONS
SWS Enclosures
SWS subwoofers are designed to bring bass virtually anywhere in a car: in front doors,
rear doors, dash board, center console, under seats, rear decks, and in any space limited
mounting depth. The following volumes shown below are created to give you optimized
"deep bass from the shallowest space".
Actual RMS power varies based on box design and on music played
SWS-15X
• Speaker diameter = 15"
• Mounting depth = 3 1/4"
• Cut out mounting hole = 13 3/4"
• Weight = 15Lbs
(81mm)
(3 1/4")
In order to match a box volume that bests suites your needs, you will need to find out the
amount of space that you have to work with, then use the formula below to find out which
range you will should be in based on our recommendations.
• Voice Coil diameter = 2.5"
• Aluminum bobbin / wire
• Power rating RMS = 400W
• Power rating MAX = 800W
• Revc = 3.76 Ohms
(350mm / 13 3/4")
(cut out hole diameter)
Choosing an enclosure type that perfectly tailors to your needs can sometimes be a hassle
and unfortunately choosing or building the wrong enclosure could potentially destroy the
sound quality of your system. The SWS subwoofers deliver truly prenominal bass response
from the shallowest of places. And in order to harness their greatness you will need to
make sure that your enclosure will be suffice for your application.
Actual RMS power varies based on box design and on music played
SWS-12X
• Speaker diameter = 12"
• Mounting depth = 3"
Sealed Enclosures:
• Cut out mounting hole = 11 3/8"
• Weight = 13Lbs
(75mm)
(3")
Do you often turn the bass down on a car or home stereo system because it sounds boomy
to you? If you do, a sealed enclosure is an excellent choice, especially if you listen to a
wide variety of music. This type of enclosure produces well-defined, strong, but not
overpowering bass.
• Voice Coil diameter = 2.5"
• Aluminum bobbin
• Power rating RMS = 300W
• Power rating MAX = 600W
• Revc = 3.76 Ohms
(288mm / 11 3/8")
(cut out hole diameter)
Bandpass Enclosures:
This bass is not really punchy, it's more like a massive, swampy force of low end that
powers the music which can be great for some tunes and extremely overwhelming on
others. If you prefer the harder stuff (metal, hard rock, industrial) or music with impact bass
content (reggae, hip hop) and you like your bass to be LOUD, the bandpass box is a great
way to go. And, if your amplifier is lacking in the power department, you'll get the most bang
for your buck from this design.
Actual RMS power varies based on box design and on music played
SWS-10X
• Speaker diameter = 10"
• Mounting depth = 2 11/16"
• Cut out mounting hole = 9"
• Weight = 11Lbs
• Voice Coil diameter = 2"
• Aluminum bobbin
• Power rating RMS = 200W
• Power rating MAX = 400W
• Revc = 3.76 Ohms
(68mm)
(2 11/16")
Ported Enclosure:
The ported box is also exceptionally loud, so it will also be a good choice if you have limited
power available. If you listen to a wide range of music and if you're always cranking up the
bass when you listen to tunes.
(228mm / 9")
(cut out hole diameter)
Actual RMS power varies based on box design and on music played
SWS-8X/8Xi
• Speaker diameter = 8"
• Mounting depth = 2 1/8"
CAUTION:
Earthquake Subwofoers are capable of generating high sound pressure
levels. You should exercise caution when operating these
subwoofer/amplifier systems. Long term exposures to high levels of sound

pressure will cause permanent damage to your hearing. Sound pressure levels exceeding
85dB can be dangerous with constant exposure. Set your audio system to a comfortable
loudness level. Earthquake Sound Corporation does not assume liability for damages
resulting from the direct use of Earthquake amplifiers or other Earthquake products , and
urges users toplay their music at moderate listening levels.

Calculating Enclosure Dimensions
Examples Of Limited Space Applications
Finding Box Dimensions For Recommended Enclosure Volumes:
To find the volume best suited for you, you will need to measure the max and min Height,
Width and Depth of the area where you to plan to place the sub-enclosure. Then subtract
1.5" each dim to get the internal dims. Now use the internal H, W & D in the formula below
to match your dims with one of our recommended ranges.
Enclosure;
Made With 3/4" Medium
Density MDF
D
W
Volume
H
External Dims:
H=10 x W=10 x D=5
Internal Dims:
H=8.5 x W=8.5 x D=3.5
To Get The Internal Dims Simply Subtract
The Total Thickness Of The MDF From The
External Dims;
Which With 3/4" MDF Is 1-1/2"
FORMULA
8.5 x 8.5 x 3.5 + 1728 = 0.15cu.ft.
CAUTION: In some cases when the enclosure will be placed with the sub facing down or
the sub butted up against the back of seat (like the illustration). You will need to either add
a grille or use 1" strips of your MDF and place as shown above. This will create an
excursion cushion so that it doesn't rub or get damaged.
