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.

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 to play their music at moderate listening levels.
