Subwoofer boxes are speakers within a box and a part of the audio speaker system reproducing the bass frequency. Subwoofer comes in different sizes, shape and design as long as the subwoofer fit in. You can put the box anywhere inside the car, truck, home and theater as long as the subwoofer looks good in its position. You can cover the subwoofer boxes to the theme of your car, truck etc.
How to build a subwoofer box:
Jigsaw
Electric drill with bits for pre-drilling screw holes and driving screws
Carpenter's glue
Silicon caulk
Non-hardening rope caulk
Speaker terminal cup
2" drywall screws
Designing the box
Measure the subwoofer its depth, diameter, height and width to determine the size of your box so that you won't waste your time, money and effort in making your subwoofer box.
Then make a sketch before doing the final job, in this matter you can overview the output of your subwoofer box.
It's not only a good sound that you will have but a good looking subwoofer box as well.
A good subwoofer can enhance the audio quality in your vehicle, home and theater. Whatever the music, it maybe soft or loud, subwoofers take part in producing a good sound. A truck sub box for the audio system can be one of the greatest ways of improving the sound.

Subwoofer Box Types - Sealed, Ported, Vented And Bandpass

So you just bought your dream subwoofer. Congratulations! You may be wondering about the different options, whether you want a sealed, ported, or a bandpass subwoofer enclosure.

Sealed Enclosure
If you have a small or a sports car, I recommend this enclosure for your car. As mentioned, it is advantageously smaller, allowing you to preserve your precious trunk space. Unless you have a high-end set that could handle higher wattage, I do not recommend on getting a sealed enclosure setup.

Ported/Vented Enclosure
Because the ported enclosure requires additional room for the vent, it is typically larger than the sealed boxes. If you're not too concerned about space, this type is a popular solution for most people. With vented enclosures, you do not need as much power coming out of your system since the lack of an airtight box allows your subwoofer to move much more freely and the vents allowing you to hear every bit of sound produced by your subwoofer.

Bandpass Enclosure
Bandpass subwoofer boxes are the largest of the three. This is because the design is based on a number of ports and two main chambers-one for your subwoofer and another for air space within the enclosure to resonate. You could probably imagine the sound produced by this behemoth. It produces the least accurate bass but with the greatest level of "boom". Also be mindful that some subwoofers do not work well in bandpass enclosures, so check your product manual before installing them. Ultimately, bandpass boxes are extremely efficient enclosures and demand much less power than the sealed enclosure. Be sure to have a tight install on a bandpass enclosure since any loose parts will easily rattle and could easily be heard on a bandpass setup.

Other Details on Subwoofer Boxes
Most subwoofer enclosures now are constructed using MDF, or Medium Density Fiberboard, these are excellent for enclosures so be sure you're buying MDF construction boxes and not cheap plastic or plywood. Carpet will protect the exterior from getting scratched and usually matches the trunk color pretty well (gray, black, and tan). Paint or vinyl finish tend to show exterior blemishes much easier than carpeting, but cleaning them is also much easier-especially valuable if you are installing a non-trunk subwoofer enclosure install.
How many subwoofers in a box? Yes, two will help add more power and sound, but it sacrifices sound quality for volume and boom.
Happy hunting!


The Best Subwoofer Box: Sealed Vs Vented Vs Bandpass
Execitive Sumarry about Subwoofer Boxes By Frank Voo

There are a wide variety of subwoofer boxes or enclosures on the market today. Many audio enthusiasts even choose to build their own boxes. The two most popular types of subwoofer enclosures are sealed and vented.

Sealed
A sealed subwoofer box is exactly what it sounds like. The speaker faces outward from the box and the rest of the box is sealed so that no air can escape. This is probably the most common type of box. Due to the fact that no air can leak in or out of the box, a sealed box produces very accurate sound and can handle very low frequencies better than most boxes.
One disadvantage of a sealed box is that it typically requires more power than a vented box. However, a sealed box is a good choice for anyone who wants a real high quality sound from their subwoofer.

Vented
Vented boxes are also known as ported boxes. These types of boxes contain a small vent or port in the enclosure that allows air to escape from the box. These boxes produce a very loud sound using less power to drive the woofer but they are also less accurate and will deliver lower-quality sound than a sealed box.
Vented boxes are tuned to a certain frequency range determined by length, width and diameter of the vent. One of the advantages of a vented box is that it requires less power to drive the subwoofer.

Bandpass
Another option that is often overlooked when people are discussing which type of subwoofer box is best is the bandpass box. This is a type of hybrid box that is essentially a combination of a sealed and vented box. Bandpass boxes are extremely efficient. One chamber is vented and the other is sealed. This produces deeper sounding bass and requires less power than a sealed box alone. However, not all subwoofers will work in a bandpass box so one needs to do their research when contemplating a bandpass box. If you are thinking about building your own box, it may be easier to go with a traditional sealed or vented box.
