PSW310X / PSW312X

ALPHASONIK WAS FOUNDED IN 1976 WITH ONE MISSION, TO

BRING STATE OF THE ART PERFORMANCE TO THE CAR AUDIO

ENTHUSIAST.

In those early years we pioneered such ground-breaking technologies as amplifier fan cooling and high voltage signal transfer which remain a benchmark in high-end audio.

Today, the new Alphasonik is committed to pushing the envelope with regard to technology, quality and value. Our electronics feature audiophile parts and circuit topology designed to let the full musical experience come through, loud and clear. Our loudspeakers employ the latest high technology materials and processes such as carbon reinforced woven glass and titanium vapor deposition to deliver your music with tremendous impact, dynamics and resolution.

We stand behind our quality with one of the best warranties in consumer electronics. Compare Alphasonik car audio products against anything competition has to offer. We’re confident you will come to one conclusion...

ALUMINUM CONE

The spun aluminum cone provides outstanding con rigidity and lowers distortion. Addtionally, the combination of strengh and weight allows for higher output levels without cone break up.

DUAL 4-OHM COPPER VOICE COILS W/ BLACK ANODIZED FORMERS

For high efficient thermal transfer, the voice coil is constructed with a black voice coil formed from anodized aluminum wound with 99.9% oxygen free copper. This makes the voice coil highly efficient in dissipating heat while improving power handling capability.

DUAL LAMINATED COTTON SPIDER (DAMPER)

The spider provides a rigid progressive suspension for the woofer cone resulting in better bass response and excursion capabilities.

HIGH STRENGTH GLASS FIBER ENHANCED SURROUND

Machine injected high strengh glass fiber enhanced rubber surround for the top suspension adds mechanical strength and reliability. This also provides a softer lighter suspension increasing effciency.

Now that you know about subwoofer specifications it’s time to learn about building subwoofer boxes. If you’ve done any woodworking you shouldn’t have much trouble when building a subwoofer enclosure. One of the main differences will probably be the material used in building subwoofer boxes as compared to other woodworking projects. When building a custom subwoofer box you will want to use minimal MDF (medium density fiberboard).

TOOLS REQUIRED TO BUILD AN ENCLOSURE

Safety goggles

Table saw or circular saw

Powered screw gun

Router or jig saw

Variety of sizes of drill bits

Wood glue

Silicone

Wood screws

To ensure your safety while building an enclosure, please read all manuals for the power tools you will be using, as they will include valuable information on handling the tools and safety tips.

If you’re planning to build your own enclosure and are confused

in what type of enclosure best suits your needs this page will help you choose what enclosure fits your needs. There are many different types of enclosures. The two most common used enclosures are sealed and vented enclosure. This page will show the advantages and disadvantages of the two enclosures.

Advantages of a sealed enclosures

*High power handing capability

*Great transient response

*Tolerant of minor enclosure size variation

*Easy to construct

*Smooth rolloff (12dB/octave)

Disadvantages of a sealed enclosures

*Requires a woofer with a long excursion for better low bass frequency response.

*Can have lower sensitivity than ported enclosures.

*When using high power and small enclosures, the woofer is not in an ideal cooling environment.

*Less low bass as compared to a properly tuned vented enclosure above the ported tuning frequency.

Advantages of a vented enclosure

*Increased output around vented tuning

*Higher power handling above the port tuning frequency

*Extended frequency response

*Magnet is in a good cooling environment

*Handles higher bass frequencies with less distortion

Disadvantages of a vented enclosure

*Vented enclosure transient response is not as good as sealed boxes because of the resonant effect of the vent tuning

*Midrange sound coming from inside the enclosure through the vent can produce unpleasant sound coloration.

*Loss of cone movement control below vent tuning, which can result in high distortion and mechanical failure of the driver.

*Lower power handling below the port tuning frequency.

Calculating speaker enclosure volume is a five step procedure.

(Make sure you do not forget to subtract the thickness of the wood that you have selected to use to build your enclosure.)

Step One: Measure Height

Step Two: Measure Width

Step Three: Measure Depth

Step Four: Height x Width x Depth

Step Five: Divide the results were in step four by 1728

(12" x 12" x 12"=1728 which equals to 1.0 cu ft.)

Complete formula should look like this

Height x Width x Depth / 1728 =__________

Below are illustrated versions of all the steps that you should take.

(FOR EXAMPLE ONLY)

18"

19.5"

The wood that we are using is 0.75" thick

The 1.5 that you see in the formula is the thickness of the wood.

Calculating thickness of wood:

Measure how thick the wood is then multiply by two.

The reason that you are multiplying by two is each side of the enclosure.

Left + Right=1.5

Top + Bottom=1.5

Front + Back=1.5

.75 x 2=1.50

18 x 12 x 12=2592

2592 / 1728=1.5

1.5 cu. ft. is the results for this enclosure

Calculating speaker enclosure volume is a five step procedure.

(Make sure you do not forget to subtract the thickness of the wood and port displacement that you used.)

Step One: Measure Height

Step Two: Measure Width

Step Three: Measure Depth

Step Four: Height x Width x Depth

Step Five: Divide the results in step four by 1728

(12" x 12" x 12"=1728 which equals to 1.0 cu ft.)

Complete formula should look like this

Height x Width x Depth / 1728 =__________

The wood that we are using is 0.75" thick

The 1.5 that you see in the formula is the thickness of the wood.

To calculate the thickness of the wood.

Left + Right=1.5

Top + Bottom=1.5

Front + Back=1.5

.75 x 2=1.50

21.5 x 13.5 x 12=3483

3483 / 1728=2.01

2.01 cu. ft. is the result for this enclosure.

Formula to calculate port displacement

3.14 x Radius x Radius x Depth=

________ / 1728=port displacement

3.14 x 2.25 x 2.25 x7=111.27 sq. in.

111.27 / 1728=.06 is the displacement of the port

2.01 - 0.06=1.95 cu.ft. is the final result for this enclosure.

Converting a round port to a slot port.

Calculate the area of the round port(s) being used, then use the square root function of your calculator to get the interior dimensions of an equivalent suare port. The length (or depth) of the slot port will be the same as that of the round port.

To calculate area: ( Area is a two dimensional measurement )

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 music source. 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 Alphasonik Dealer. Never sacrifice your safety for sound.
