Choosing an Enclosure
Choosing an enclosure can be one of your most difficult decisions. There are several types available. The definitions
listed here are for the most common: Sealed, Ported and Bandpass. This will help you choose which enclosure is best
suited for you.
Sealed Enclosures: This is the most common enclosure to use for several reasons. They are the easiest to build
and utilize the least amount of space. The response of the driver is tight and controlled. Since the enclosure is airtight,
the woofer does not flop around or loose control when played at high volumes. The disadvantage of a sealed enclosure
is that you need more power to drive the woofer. Sealed enclosures are perfect if you want a wider frequency bass
response and the most accurate sound reproduction possible.
Ported Enclosures: Ported enclosures are generally used with low frequency drivers. Although they are harder to
build than sealed enclosures, ported enclosures have a rough estimate of 3 dB (decibels) of increased volume than a
sealed enclosure. To gain that kind of increase with a sealed enclosure, you would need to double the power of the
amplifier. While ported enclosures benefit from increased efficiency, they are not as precise as a sealed enclosure. As
compared to a sealed enclosure, ported boxes suffer from poor driver control at low frequencies. Ported enclosures
trade their efficiency for ultimate bass extensions.
Bandpass Enclosures: The best way to describe a bandpass enclosure? They are half sealed and half ported. A
bandpass enclosure uses a sealed enclosure and a ported enclosure to amplify the bass response. The advantages of
a bandpass enclosure are simple: accurate bass response at lower frequencies. The disadvantage is that they only
play low frequencies and the frequency range is very narrow, no more then a 30-Hertz frequency spectrum from where
the enclosure is tuned. The worst part of a bandpass enclosure is you will never know when you are overplaying the
woofer(s). Since the waves are generated in the ported side of the enclosure and then fires through the ports, the
distortion will remain in the enclosure. This is the main reason manufacturers do not support bandpass-designed
enclosures. We do not recommend using any woofer in a bandpass enclosure unless the woofer was specifically
engineered for a bandpass enclosure.

Building An Enclosure
Calculating enclosure volumes is simple we are going to give you the mathematical equation of how to calculate the enclo-
sure that you intend to build. If you were to build an enclosure your mathematical equation should look like this HEIGHT x
WIDTH x DEPTH / 1728 = ____________ Box volume. Do not forget to subtract the thickness of the wood that you have
selected to use. The most common material used would be ¾”MDF (medium density fiberboard).
EXAMPLE:
If you were to build a one cubic foot enclosure and you have chosen to use ¾” MDF material your outside
dimensions would equal 13.5” Height x 13.5” Width x 13.5 Depth. Then you would subtract 1.5” from your Height, Width, and
Depth. The reason you would subtract 1.5” instead of 0.75” is that you are subtracting the wood on booth sides front and
back, left and right, and top and bottom. So the internal dimensions are 12” Height x 12” Width x 12” Depth. The math-
ematical equation would be
12 HEIGHT x 12 WIDTH x 12 DEPTH / 1728 = 1 CUBIC FOOT. Although we used a perfectly square enclosure for this
example. The enclosure does not have to be square. The enclosure can be any shape that is preferred.
NOTE: Do not forget to subtract your woofers displacement. After you have subtracted the woofers displacement your
enclosure would become smaller than 1 cubic foot. This mathematical equation is in inches and should be converted if
needed.
Width 13.5”
Height 13.5”
Depth 13.5”
Height 12”
Width 12”
Black= Height
Red= Width
Blue= Depth Height 13.5” Height 12”
Depth 12”

Building An Enclosure
Now that you have an understanding of how to calculate an enclosure with equal top and bottom dimensions, we will show
you how to calculate the volume of an enclosure with unequal dimensions (Wedged Enclosure). Since the top and
bottom (or sides) are of unequal lengths, measure each length (i.e. Top is 7” and bottom is 9”) and add them together for a
total of 16”. Dividing this by 2 gives the number to use for both top and bottom lengths (or sides, etc.) The process is
similar to an enclosure with equal dimensions with the exception of an added equation. The complete formula will look
like this:
Height x Width x {(Top + Bottom) / 2 = Depth} / 1728 = _______
EXAMPLE
The external dimensions of a 1 cubic foot enclosure are 13.5” height x 13.5” width x (11.5” top depth x 15.5” bottom
depth). First calculate the top and bottoms depth measurements. We have chosen to use .75” MDF making the internal
dimensions 12” height x 12” width x (10” top depth x 14” bottom depth). Add the top and bottom depth then divide by 2
{(10 + 14) / 2 = 12}. Now calculate the enclosure’s volume:
(Height 12” x Width 12” x Depth 12”) / 1728 = 1 cubic foot
Black= Height
Red= Width
Blue= Depth
Width 13.5”
Height 13.5” Height 12”
Width 12” Depth 15.5”
Depth 14”
Depth 10”
Depth 11.5”

Building An Enclosure
To build a Ported Enclosure, the port’s displacement must be factored in. The mathematical equation to calculate port
displacement is:
(Pi x Port Radius x Port Radius x Port Depth) / 1728 = _________ Port Displacement
EXAMPLE
For this example, we will use a 4” port with a depth of 7.5”.
{Pi (3.14) x Port Radius (2”) x Port Radius (2”) x 7.5”} / 1728 = 0.054 Port Displacement Subtracting this from the
enclosure volume (1 – 0.054) gives a total enclosure volume of 0.946. Remember to subtract the woofer’s displacement,
supplied in the Recommended Box Sizes section of the Owner’s Manual.
Slot Ports have become more popular than circle ports. The mathematical equation to convert a circle to a Slot Port is:
Pi x Radius x Radius =___________ square inches
EXAMPLE
We will convert a single 4” circle port with a depth of 7.5”.
The mathematical equation is Pi (3.14) x Radius (2”) x Radius (2”) = 12.56”.
12.56 square inches is the conversion used to make a Slot Port. Whatever dimensions used for the slot port, the calcula-
tion needs to be 12.56 square inches. Therefore, the slot port would be 1” wide and 12.56” tall. To make a slot port we
simply multiply Height x Width = 12.56 square. The depth of the port will remain the same. Your converted port dimen-
sions would be 1” wide x 12.56” tall x 7.5” deep.
(NOTE: Do not forget to calculate the slot port’s displacement; it takes more air space than a circle port. When calculating
the port’s displacement, also calculate the thickness of the wood.)

Fs: This parameter is the free-air resonant frequency of a speaker. Simply stated, it is the point at which the weight of the moving parts of
the speaker becomes balanced with the force of the speaker suspension when in motion.
Understanding Thiele / Small Parameters: Thiele / Small Parameters is used for box building programs that are available to the loudspeaker
inthusists. Any loudspeaker inthusist can purchase a box building program and have a box engineered specificly for the loudspeaker that they
posis. If you are a loudspeaker inthusist you will need the Thiele / Small Parameters to get the best performance out of your subwoofer / woofer.
Qes: Qes is a measurement of the control coming from the speaker's electrical suspension system (the voice coil and magnet).
Qms: Qms is a measurement of the control coming from the speaker's mechanical suspension system (the surround and spider).
Qts: Qts is called the 'Total Q' of the driver at Fs. Qts is a measure of the driver's tendency to resonate at Fs, based on its overall characteristics.
Vas: Equivalent air compliance. The volume of air that has the same compliance as the driver's suspension.
Re: This is the DC resistance of the driver measured with an ohm meter.
Le: This is the voice coil inductance measured in millihenries (mH).
Mmd: Mass or weight of the speaker cone assembly (cone, coil and other moving parts).
Xmax: Linear (one-way) travel of the cone. Xmax is used to determine the maximum linear SPL capability of the driver.
RMS: This parameter represents the mechanical resistance of the driver's suspension losses.
Sd: This is the actual surface area of the cone, normally given in square com.
SPL: Sound Pressure Level, usually measured at 1 watt, at 1 meter in front of the loudspeaker.
no: Free air reference efficiency. This is given as a percentage.
M.D.: Mounting depth of the speaker.
C.H.: Cut out hole of the speaker.
EBP: The measurement is caluculated by dividing Fs by Qes. The EBP figure is used in many enclousre design formulas to determine if a speaker
is more suitable for a closed or vented design. An EBP close to 100 usually indicates a speaker that is best suited for a vented enclosure.
An EBP closer to 50 usually indicates a speaker best suited for a closed box design.
BL: The magnetic strength of the motor structure.
THIELE / SMALL PARAMETERS
Allot of loudspeaker inthusists do not understand what Thiele / Small Parameters are. This section of the manual will help you understand what
Thiele / Small Parameter means.

WARNING & DISCLAIMER
Investigate the layout of your vehicle thoroughly before drilling or cutting. Take care when you work near the gas
tank, gas lines, hydraulic lines, electrical components and electrical wiring. Do not use the equipment unmounted.
Attach this system securely to prevent damage, particularly in the event of an accident or aggressive driving.
Do not mount the system so that wire connections are unprotected or are subjected to pinching or damage from
nearby objects. Before connecting or disconnecting power connections at the system power terminals, disconnect
the +12V DC wire at the battery end. Confirm that your source unit and other equipment are turned off while
connecting the input terminals. If you need to replace the power fuse, replace it only with a fuse identical to the
provided fuse.
Using a fuse of different type or rating may result in damage to the system, which is not covered by the
manufacturer's warranty. Do not install any product where it may be subjected to excessive heat, moisture and
dust or where it may be repeatedly kicked, brushed or bumped.
Make absolutely sure that the terminals for the products are connected to the proper inputs and outputs from the
source unit. Never run the wiring on the outside of the vehicle or under it where it can be damaged by road
hazards or any moving parts of the vehicle. Use existing wire channels, sills, panels and molding strips inside the
vehicle to hide the wiring for safety and a neat appearance.
DISCLAIMER
IMPORTANT: Never cut any metal that is an integral part of the vehicle's safety or structural support system. If
you are unsure, it is best to have the product professionally installed by an Authorized Swiss Audio Dealer. Never
sacrifice your safety for sound.
