DEAR VALUED CUSTOMER
Congratulations are in order... You are now the proud owner of an SWS Shallow Mount
Woofer: the most advanced
shallow woofer technology to hit car and home audio. The idea is simple: to generate deep
bass from the shallowest space. For years, audio manufacturers attempted to reduce the
mounting depth of a driver; nevertheless the speaker size/diameter still played a major role
in dictating the mounting depth. Approximately, a speaker mounting depth remained to be
about ½ the size of the speaker diameter: the larger the speaker the deeper the mounting
depth.
Audio, video, and data processing components have gotten better, faster and smaller. This
is true except when it
comes to speakers design, conventionally designed drivers remain “bulky” in comparison to
other audio components. In 1929, Mr. H. Shotwell designed the first “front loaded magnet”
driver, it was a small step in reducing the mounting depth of driver. Since then, other audio
manufacturers (such as Bose, Harmon and others) made several attempts to reduce the
mounting depth of a driver. Nevertheless, the speaker mounting depth remained to be
about roughly half the size of the speaker diameter - the larger the speaker the deeper the
mounting depth. This “handicap” held true until few years ago when Joseph J. Sahyoun
(Vice President, Inventor, and Head Engineer at Earthquake Sound Corporation) started
developing the shallow mount woofer system (SWS). The “SWS” presented a radical
solution away from the conventional “bulky” speaker design.
The SWS design reduces the mounting depth of a speaker by over 60% without taxing its
performance. These
numbers look even better as the speaker diameter increases. A conventional 12” woofer
has a mounting depth of 6 to 7 inches (for a ± 1” excursion); on the other hand, an SWS-12
performs the same in a little less than 3” of mounting depth. The SWS design allows the
installer to use compact enclosures, whereby the mounting depth is about 1.5 times the
peak-to-peak excursion. The SWS technology makes the speaker mounting depth
“excursion-dependent” and not “diameter-dependent”. Once a target Xmax is set, the
mounting depth follows (1.5 times the peak to peak excursion); the Xmax remains
independent from the size (diameter) of the speaker. The SWS opens the door for
unrestricted bass applications where a conventional subwoofer could never be used.

NOTE: The 2-Ohm SWS-8Xi is designed to replace subwoofer in factory
upgraded vehicles, such as BMW's, Corvettes, Mercedes Benz and
much more.
In home applications, SWS allows the designer to build 12” in wall woofer that moves 2”
peak to peak while
maintaining a mounting depth of less than 3”. This technology opens the door for home
theater designers to squeeze large woofers in very tight spaces / closets, also to do in-wall
woofer application. In car applications, rear-deck subwoofer mount - used by manufacturers
of luxury automobiles- represents a prefect example of a totally stealth install (using 10”,
12”, 15” SWS). 8” door mount with 1” peak to peak now is possible where mounting depth
is a mere 1.5”; with a possibility of using 10” SWS in the doors of larger SUV's.
The aluminum custom-made cone and dust cap are designed to reduce the voice coil
temperature by dissipating the
heat that builds up in the voice coil. The dust cap is directly fastened to the voice coil
aluminum bobbin, it transfers the heat build-up from the bobbin into the cone. Both dust cap
and cone act as a giant heat sink to reduce the voice coil temperature and increase its
power handling and endurance. The high roll pressed-foam surround is coupled with a
propagating spider to allow for extreme excursions with no limitations. The slick shallow
basket is coated with black chrome and is shaped with slant edges for easy install in tight
spaces.

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".
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.
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.
Sealed Enclosures:
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.
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.
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.

Calculating Enclosure Dimensions
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.

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.
