Parts You Will Need To Build Your Enclosure

When building a subwoofer enclosure you will find that there are numerous materials recommended for construction.

1)Medium density fiberboard (MDF)

2)Marine grade plywood

3)Particle board (the smaller the particles the better)

These materials range in price as well as availability. Particle board is the most common, least costly, and can be purchased at most hardware stores. MDF and marine grade plywood, although preferable, are usually much harder to find, and much more costly. Whichever you choose, we recommend that its minimum thickness be 3/4". This will provide the rigidity necessary for optimum performance.

If you’ve never built an enclosure before we are going to try to make this as easy and painless as possible. If you’ve built enclosures before you can skip this section and go right to the technical sheet to get your parameters.

Complete Parts List:

1)Wood (particle board, MDF, or marine grade plywood) 4' x 8' x 3/4" sheet

2)Wood glue (one 12-16 oz. bottle)

3)11/4"x #8 wood screws (one lb. box)

4)Caulk gun and silicon caulk (two tubes)

5)Terminal cup (one per speaker) available at electronic parts stores

6)Speaker wire (2-4 ft.)

7)Carpet (optional)

8)Grills to protect your subwoofers (optional)

9)Solderless speaker connectors (available at electronic parts stores)

Designing Your Polk dX Subwoofer Enclosure Step By Step

1.) How much room do you have to work with in your car or truck?

When designing your subwoofer enclosure, the first thing you need to figure out is, just how large an enclosure will fit in your vehicle. When an enclosure is going in the trunk of a car, you first need to measure your trunk to find the maximum height, width, and depth you can use. Pay attention to trunk hinges and tension bars. If your enclosure is going in an area other than a trunk, make sure you check for similar obstructions. After measuring, subtract 1.5" from each dimension. This compensates for the thickness of the material you use (simply double the thickness, i.e.: if you’re using 3/4" material, subtract 1 1/2"; 1" material, subtract 2", etc), and will give you your usable (internal) dimensions. Record these dimensions here for future reference.

Maximum dimensions

Usable dimensions

Height:__________ inches

(Minus 1.5 inches)=______inches

Width:___________inches

(Minus 1.5 inches)=______inches

Depth:___________inches

(Minus 1.5 inches)=______inches

 

Usable volume=________cubic inches

 

Usable volume=________cubic feet

Multiply your usable Width x Height x Depth. The product will be the usable (internal) volume of your enclosure in cubic inches. Divide this number by 1728 (the number of cubic inches in a cubic foot). This will give you the internal volume in cubic feet. Divide your internal cubic feet by 2 (only if you are using a pair of dX subwoofers). Compare this number to the chart at the bottom of the technical sheet. Choose the recommended enclosure which is closest in size or that fits your desired type of enclosure. Now that you have all of your needed dimensions, you can begin cutting your wood. From the above chart you can tell how big each piece of wood should be.
