What is a Subwoofer?


A subwoofer is a loudspeaker that is complete in its development. This means that a subwoofer completes the whole sound of music. These devices are dedicated to mak-ing an audio system better with its low-pitched frequencies, better known as bass. A common frequency range for a subwoofer is between 20 Hz and 200 Hz. Anything below 100 Hz is for professional use, and below 80 Hz is for approved systems that are THX certified. A subwoofers’ job is to complete the range of the loudspeakers, by inserting more low sounds to cover up some of the higher sounds made by regular speakers. The term subwoofer is referred to as a ‘speaker drive,’ and is usually mounted some way within a vehicle.

History of the Subwoofer


Subwoofers were first produced in the early 1960’s. They were created to add bass to stereo systems at home. The popularity of subwoofers started to catch fire in the 1970s, with the production of the ‘Earthquake,’ which added low-frequency additions to high-frequency music. In the 1980’s, recording studios began to emphasize bass in their tracks, so it could be heard on a home stereo system.

In the 1990’s, DVDs increased the recorded sounds of bass, and surround sound was born, bringing sub-woofers fully into the fold of audio electronic device. Subwoofers started to become the norm for home theater systems and in car audio settings as well.

By the early 2000’s, subwoofers became universal in concert and nightclub settings. Today, sub-woofers are everywhere, and they are becoming better and less expensive than ever. This is good news because from today, people already have plenty of options to choose from and many can already afford to invest in a good quality subwoofer for their cars.

Loud Subwoofers

To find a subwoofer that plays the loudest or delivers the best SPL, you will need to think about sensitivity, available power, and the enclosure type. With sensitivity, find a subwoofer that has great efficiency; these are usually rated in a bandpass box or a ported box (mention of these two later in the article). Next, the power for the sub comes from an amplifier.


Each sub has a recommended range of power that consumers can usually use up to the top 1/3. Going over this range could be detrimental to your hearing and the subwoofers themselves. If you are looking for the slam of power when using subs, consider using a bass boost control to help. Also, using more than one subwoofer could help with overall sound. More power will always make for a louder sound, but more power cost more money in the form of an amplifier.

Subwoofer Depth

If you are looking for the lowest possible sound from your subwoofer, then select a large woofer in a box that is sealed. An enclosure like this will drive the frequency response time down, giving you a sound with more depth. Make sure you know how much your amplifier can handle, in the form of watts. The more wattage you have, the lower frequency you will get to your subwoofers.


More often than not, larger subwoofers give off a deeper sound than small devices, but this is not always the case. Depending on the brand, smaller subwoofers can give out a great, deep sound, too. If you are looking for more depth in your vehicle, take your subwoofers to a trained professional. They may be able to tell you what you need to get a deeper sound in your car. Sure, this might end up costing more than you do-ing the installation or the fix yourself, but you will get a professional opinion as to what you could do next.

Subwoofer Enclosures


Usually, subwoofers have one or two woofers mounted in an enclosure, within your vehicle. These are made of wood which is capable of withstanding the pressure that comes from the air within the speakers. Subwoofer enclosures help resist deformation of the speaker and the enclosure space itself. Enclosures can come in a variety of options.

There are bass reflex enclosures which have a passive or port radiator inside. There are acoustic suspension enclosures which are completely sealed, keeping the sub-woofers stable. There are also infinite baffle, bandpass, and horn-loaded designs, which represent different tradeoffs of bandwidth, size, price, and efficiency for each subwoofer. Depending on which one is right for you, there are many enclosures that will fit your needs and preference.

Active vs. Passive Subwoofers

There are 2 versions of subwoofers. These are 2 things that you should also consider before picking and deciding on which subwoofer to purchase. Active subwoofers have an amplifier that is built-in, giving you direct power from the device itself. A passive subwoofer has a drive and enclosure but is powered by a different amplifier that is not built-in.

Each of these versions has its pros and cons, but ultimately, it comes down to price. Passive subwoofers are usually cheaper, but then you would have to purchase an amplifier on the side. Active subwoofers are more expensive, but everything you will need is in one subwoofer.
