SPECIFICATIONS

Die Cast Basket

The S4 Series Woofers uses a die cast basket for better voice coil alignment.
The basket is aluminum and non-magnetic for better efficiency. In Addition,
the aluminum dissipates heat far better than steel which allows more power
handling. The Q of the speaker will be much higher than with a stamped steel
frame, thus giving a lower resonate frequency.

Non-Pressed Paper Cone

The cone is a spruce pulp paper that has been treated with a water resistant
Poly Vinyl Acetate (PVA) emulsion. This provides cone rigidity and lowers
distortion. Additionally the combination of weight and strength allows for high
output levels without cone break up.

Single 4 Ohm Aluminum Voice Coil

For High efficient thermal transfer the voice coil is constructed with a black
voice coil formed from anodized aluminum. This makes the voice coil highly
efficient in dissipating heat thus improving the power handing capability.

Dual Laminated Dupont Spider

Provides strong suspension for the subwoofer, which results in higher
excursion capabilities.

Hyper-Extended Pole Piece

Better low frequency response is obtained by having a better linear
magnetic field for the operation of the woofer.

Foam Surround

Double Treated Foam for the front suspension is proven to add mechanical
strength and reliability.

CALCULATING ENCLOSURE VOLUME

Do you want to take up all the available space inside your Vehicle? Or are
you looking for something that is compact enough to be removed easily when
necessary? These are important questions you must answer before beginning
your project.

First, measure out the area you’re interested in placing the subwoofer
enclosure. Use a good-quality measuring tape to determine the MAXIMUM
height, width, and depth of your area. Height is the measurement up-and­down, width is the measurement from side-to-side, and depth is the
measurement back-to-front.

It is extremely important to know the internal volume necessary for the
Subwoofer you’re using (also known as “box size”). Since not all subwoofers
require the same amount of airspace, different lines of the same brand of
woofer can have completely different enclosure size requirements. As general
rule of thumb, making the enclosure too small will result in a lack of low-end
bass response, and if it’s too large, you won’t have as much output as you
could and the woofer’s power handling will suffer.

Calculating the correct box size is easy if you just remember a few simple
formulas and calculations. The key to calculating internal box dimensions is a
basic understanding of volume: Cubic volume is derived by multiplying each
of an object’s dimensions (height, width, depth) by each other.

For example: If you measure the
internal dimensions of a rectangular object
(like a subwoofer box) and its internal
height is 12", its width is 24", its depth is
12", and then multiply those dimensions
together (12" X 24" X 12"), then you come
up with a volume of 3,456 cubic inches.
Divide this number by 1728 (1 cubic foot)
and the total is the internal cubic volume of
the box, which in this case is 2.0 cubic feet.

Enclosure volumes are never listed in cubic inches, so it is necessary to
convert from cubic inches to cubic feet. (A cubic foot is no more than
12" X 12" X 12" or 1,728 cubic inches.) So, to convert from cubic
inches to cubic feet, simply divide the volume in cubic inches by 1,728.

ENCLOSURE CONSTRUCTION

Once the chosen the type of application for your subwoofer(s) and the
dimensions of the box are calculated, the materials need to be selected. The
following is a list of common enclosure construction materials:

Particle Board: Very inexpensive, however this board tends to come
apart under the high stress of subwoofers, and is very susceptible to water
damage! Not suitable for very large enclosures unless a great deal of internal
bracing is added for extra rigidity.

Medium Density Fiber Board (MDF): The best overall material for
speaker enclosures, fiberboard is extremely rigid, and will not come apart at
even the highest pressure levels.

Plywood (all types): A poor choice for car stereo subwoofer
enclosures, as plywood tends to de-laminate under heat and weather ranges
found in cars. It can also buzz at low frequencies when played at high volume.

The thickness of material for the enclosure is governed by the overall size
of the enclosure. The smallest of enclosures (1.0 cu ft or less) can use 5/8" or
1/2" material. Average size enclosures (1.0 cu ft to 4.0 cu ft) should use 3/4".
Very large enclosures (over 4.0 cu ft) should use 1" material with braces to
prevent enclosure flex.

Adding damping material, such as fiberglass, or Dacron polyester (pillow
stuffing like Poly-Fill) to your subwoofer enclosure helps cancel any standing
waves or resonances that form in the enclosure because of its particular
dimensions. We recommend adding stuffing only to sealed enclosures. It will
not make up for a poorly-constructed enclosure or an enclosure that is built too
small, but it can help make the enclosure play low frequencies with added
emphasis. It is possible to make your speaker think that it is in a larger box
than it actually is by adding extra damping material, up to 75% of the entire
enclosure volume. The general rule here is to add 1 pound of fill material (R­19 fiberglass, Dacron, or lamb's wool) per cubic foot of enclosure volume.

Always follow the above general rule of thumb when selecting the amount
of Fill. Fill should only be used for sealed enclosures only. This fill
recommendation can be found on the Parameters and Specifications Page.
Don’t compress the material, just loosely add fill to the enclosure. This works
because the fibers of the material cause the sound waves to bend around them,
slowing the waves down and taking longer to reach the enclosure’s sides. As
much as a 15% change in box volume/response can be achieved by this
method
