Subwoofer enclosures are an essential part of any music lover's car sound system, because they are affordable and easy to install accessories that instantly add bass to your system. But, there are literally hundreds of 'low-frequency reinforcement' subwoofer enclosures to choose from.

Subwoofer enclosures protect your subwoofers and greatly affect sound quality. Generally speaking, you should purchase subwoofers that come subwoofer enclosures, because manufacturers specifically designed the enclosure to compliment your sub. But if you already have subs in place, and just need enclosures, you can find them. All you need to know is how to choose from four different types: tube, ported, sealed or bandpass.

Sealed enclosures are found to deliver highly accurate, 'hard-hitting' bass sounds. If you do not like a 'boom' sound quality, then this type of subwoofer enclosure is perfect for you. It produces a crisp and clean sound for any type of music.

Bandpass subwoofer enclosures, on the other hand, deliver 'thick' bass, perfect if you want to listen to loud music. It works really well with certain types of beat such as hip-hop and reggae.

But, if you tend to listen to different music genres, then perhaps something a bit more generic is best like the ported subwoofer enclosure. Experts agree that this type is the most versatile. Any kind if music sounds good with it. Ported subwoofer covers also amplify sound, so it's perfect if you have limited power but want to play loud music.

Executive Summary about Subwoofer Enclosures by Mark Markham

When it comes to loud pounding bass the big secret is that the quality of your speaker box is more important than the quality of your sub woofers. With your vehicle's sub woofer box, bigger is not always better.

Proper sizing of the sub woofer box so important, because proper sizing allows for proper placement in your vehicle, proper placement means that you and your passengers will all enjoy the same high quality sound from your stereo.

Subwoofer enclosures allow you to upgrade 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.

5 Essential 'Must Do's' When Building a Subwoofer Enclosure
Executive Summary about Subwoofer Enclosures by Marie Coles


One:
Find out what design and size is best for your subwoofer.
The wrong design or size could affect the performance of the subwoofer in your car, making your system worse rather than better.
The manual should tell you the free amount of air space between woofer and enclosure needed, whilst a simple equation where you find the EBO (efficiency bandwidth products) can help find the best type of design.
Alternatively, the manual or a car audio expert may have suggestions on design.

Two:
 Decide upon how many enclosures you may need.
Although it is not necessary to create two separate enclosures, it practically works better.
A sub enclosure can also be separated down the middle in two, so that one sturdy box fits two subs in.
If no divider is there though, and one subwoofer malfunctions, it will leave double the amount space needed for the other sub, which will affect the performance of your system.
Separating the subs, whether by separate enclosures or a divider (known as twin enclosures), will prevent this from happening.
If you have one sub alone, this makes the decision far easier as you will have only one enclosure to build.

Three:
Think long and hard about the materials you are going to use in your enclosure.
The enclosure is required to be a hard rigid structure, so that the subwoofer is safely in place and can do its job correctly.
Without a rigid structure, the sub can easily be damaged and will not perform as it should. Therefore, the material used needs to be strong and firm, for example, wood, MDF, fibreboard, thick particle board or thick Plexiglas are all used regularly in enclosure structures.
Another choice is mould the enclosure into a shape using fiberglass. However, this is time consuming due to the many layers needed.

Four:
 After thinking about the material, consider how you are going to make sure it is a fixed and firm structure? Adding braces and strengthening weak points, such as the corners will help keep together your structure.
Complete a design on how you are going to strengthen your structure beforehand and remember that any reinforcement or brace will take up air space, which means you'll need to expand the interior space in the enclosure design in accordance with the space lost to the brace.

Five:
When using nails and drills always be careful.
You don't want to unnecessarily drill holes or break the structure via screws.
The joints are a particular area, which can be easily damaged by screws.
Avoid potential damage by distancing your screws out with equal spaces and drilling over half way prior to the screws being placed in, as this will stop the wood from breaking.
