Composing A Subwoofer Enclosure: Which One?

A Subwoofer enclosure not only acts as way of mounting subwoofers in your car, but is a fundamental way of preventing sound waves from the behind the driver interfering with the sound waves at the front. An enclosure will amplify the quality of sound and will enable the subwoofer to work at its highest capacity.  There are a number of enclosures available, all with benefits and disadvantages.

When investing in a subwoofer, it's indubitably very important to buy or create an enclosure that accentuates the volume and quality of sound. Each enclosure type is effective to a certain extent, but you may have to sacrifice space in your car for a greater output.

The Infinitive Battle enclosure

 The subwoofer is mounted on a piece of board or the rear deck, which then separates the front cone from the back. The main advantage of this enclosure is the fact it takes up very little space and is economically priced. On the other hand, this model requires a lot of power and sound reproduction is often not as accurate as it could be. Separation of the two cones can also be difficult; meaning you still may get interfering waves.

The Sealed Enclosure

The sealed enclosure is simplest of them all – a sealed box separates the front cone from the back, dealing with any interference problems. Its main advantage is size, as these can be made from big to small, and it is also ideally compact. The only problem is that it requires a Great Deal of power, and is also not as good as dealing with low bass than a vented enclosure.

The Ported or Vented Enclosure

Similar in design as the sealed enclosure, this design only adds a port, which is usually a PVC pipe tuned to a certain frequency determined by the two factors, area and length. By inserting this port, the rear wave from the back cone reinforces the front wave, in turn enabling greater power efficiency. Although, this design is a little complex and it needs more space than its simpler predecessors, it does provide a lower frequency extension – so that you adequately hear the lower frequencies in your music.

The Band Pass Enclosure

This system's main purpose is to boost efficiency over a miniscule series of frequencies. This enclosure dampens out mid-range to higher frequencies, making it perfect for drum ‘n' bass.  This type of enclosure has a number of variations, known as orders, all of which have a different type and number of vents. Its main asset is its high efficiency and its ability to filter out higher frequencies, yet, frequency response is also decreased as well as the quality of reproduction. 

 

An enclosure will let your subwoofer to work at its best, providing you either with intense volume or superior sound quality. When thinking about subwoofers and enclosures, it's important to consider how much space you have. There's no point buying a subwoofer that is too big for your car, and extending the amount of space used by using a large enclosure.  If space is a problem, but you don't want to sacrifice volume, then have a look at much smaller squared subwoofers and combine these with the most appropriate enclosure.
