Subwoofer Box - Subwoofer Enclosures

Subwoofer boxes allow you to upgrade and enhance your car stereo system without detracting from the appearance of your car or truck. Many people have great ideas about upgrading or even building a custom stereo system, but think they'll have to sacrifice looks to get the sound.

There are 3 major types of subwoofer boxes (enclosures).


- Sealed Enclosures (Isobaric):
Sealed sub enclosure is considered to be one of the most used enclosures in SPL competition because it makes great low level power handling and require less space than most subwoofer boxes. A sealed subwoofer box is completely airtight enclosure.

Advantages of sealed subwoofer enclosures:

- Sound performance doesn't get affected due to design errors.
- Simple to build and design.
- Great power handling.

Disadvantages of sealed subwoofer enclosures:

- Distortion at high frequency.
- Because of the design of a sealed box, the magnet will not cool easily.
- Require more power to reach comparable output levels than a vented box.



- Ported Subwoofer box:

It provides flat response to just above a low-frequency 3-dB, with system output rolling off at some rate below that frequency.

Advantages of ported subwoofer enclosures:
- Lower distortion because of the limitations of mechanical suspension.

Disadvantages of ported subwoofer enclosures:

- Hard to design and build.
- Sound performance gets affected due to design errors.

- Bandpass subwoofer enclosures:

A Bandpass box is essentially a ported subwoofer box with another enclosure mounted to the front of it with another port or vent. It's very important to design the sub boxes the right way to eliminate low sound performance.

How to build a subwoofer box
Consult first with the manufacturer or the retailer of your subwoofer speakers. Ask them about the dimensions of the box. Then, ask them also if the given dimensions are interior or exterior. Interior dimensions would have to include the inch thickness of the wood. On the other hand, for exterior dimensions, the manufacturer has already took that into consideration.

To start off, you should have these tools and materials for you would be using them as you proceed with this task: a inch medium-density fiberboard, a jigsaw, a router, a power drill, a down spiral or a spiral bit, a inch bit, a file, some sandpaper, a razor blade or a scalpel, some spray glue, a tape measure, a pencil, some screws, silicone, a solder, a solder gun, a calculator, some scratch paper, and your car's carpet.

Start the constructing process by using your pencil and tape measure to trace out the patterns of the enclosure on the fiberboard. Trace out the patterns for the six sides of the subwoofer box. Also add in a center divider for inside the box which would serve as the separation between the two speakers. Cut these patterns out with the jigsaw.

Sub Woofer Tip! Should you want to build the 'optimal' box for your subwoofers, be sure to check the manufacturer website of your subwoofers before building. Take the pattern for the top portion of the subwoofer enclosure. Use the frame of the grille of the subwoofer speaker and a pencil to trace the outer and inner portions of this. Do this on the location of the board where you would like to put in your speakers. Use the router with a inch bit and cut a depth of 3/8 inch. Do this between the inner and the outer circle, and this area would be the place where the frame of the speaker will be flush mounted.

Cut the holes for the speakers using the jigsaw. Later on, use a file to smooth the edges. You can also use the sandpaper to smooth out the area. Then, cut out round holes measuring two inches. Do this on each of the side panels. These holes will be filled with the connectors for the speaker wires.

Using screws, assemble the box. Seal the joints with silicone. This is to ensure that air will not leak out. Leave the front panel off first. Then, spray glue on the outer portion of the box as well as on the back of the carpet. Wrap the carpet tightly into the box. Put in some carpet at the top panel. With the use of a razor blade or a scalpel, cut vertical, horizontal, and angled lines in a star pattern into the carpet. Then, cut out the carpet that covers the connector holes.

Place in the connectors and make them run through the holes. Make sure that the two prong terminals are inside the box. Then, screw down the connectors. Seal around them with silicone. Solder the speaker wires to the speaker and connector. Also solder the positive wire to the positive lead of the speaker. Do the same with the negative ends. After everything has been done, put in the front panel on the box and screw them in. Push the speakers into the star pattern cut out on the carpet that covers the speaker holes on the front panel. You can now install the box inside your car and enjoy the music. Custom Subwoofer Box
