When we hear the word "subwoofer", we automatically think of a speaker for bass. But that's not always true. There are also "bass-reflex" subwoofers, which might not have a box at all and can be placed in different positions inside the cabin. Then there are subwoofers built into multi-channel amplifier systems from audio system sellers or manufacturers themselves.
I know you're probably thinking to yourself that every subwoofer for cars is basically the same. However, there are definitely different kinds of subs and they each have a unique set of traits. So let's get started with some basics:
Boxed Subs
A boxed sub enclosure works by putting the speaker within it, then closing the box with fabric. It has bracing inside to hold it together and provide more support for the speaker. Enclosures offer a good, controlled bass response with generally minimal distortion and good sound quality overall.
Sealed Subs
A sealed sub enclosure works by putting the speaker within it, then closing the box , which is usually also covered in fabric. Sealed boxes are just as effective at providing solid bass as other types of enclosures, but they are small-sized so they fit well into smaller spaces on your vehicle's floor or trunk too!
Ported / Vented Subs
The porting system allows air to pass through freely inside a tuned vent to create a better sound. The air pressure in the port is higher than at the back of the speaker because it has been "worked" by going around a bend. It works somewhat like a turbocharger.
The vent is tuned to be about ¼ wavelength long for a particular subwoofer. This means that if you have a box with a length of 2 feet, then half of that will equal 1 foot. The air needs to travel 1 foot through the vent and when it does, it loses some energy and gets compressed as well.
Don't worry, adding more subs doesn't double your power or anything crazy like that although they do offer better sound quality than other types of enclosures.
Underseat Subs
Underseat subs are a popular option for cars because they hide away and provide a good amount of bass. You'll have to take your seat out, but you can then place an enclosure under the carpet or vinyl flooring of your vehicle's seats. Alternatively, there are some models that will easily slide into the space in between the back of your seat cushions and the chair itself.
Sealed subwoofers for cars try to create as tight a seal as possible with compression rings or rubber gaskets inserted on either end of the box too. The tighter you make this internal seal, the better it is at producing punchy sounds from low frequencies when combined with other speaker components within your car audio system.
Bazooka Subs
Bazooka subs or bass tubes have become a popular choice for car audio enthusiasts because of their reputation. They are typically used in sealed enclosures and they're known for producing good quality bass that is also quite loud, though with susceptible distortion at high volumes.
Shallow Mount Subs
Subwoofers that are meant to be mounted in a shallow manner have a mounting depth that is relatively shallow. They work well in confined quarters and may be put to service in slender places.
These mount subwoofers may produce bass in confined spaces such as a compact automobile or similar environments. They are simple to set up, in addition to being lightweight, small, and flat. These are small yet can provide great bass to any vehicle.
If you want to boost the audio quality in your vehicle but don't have a lot of room, a shallow-mount subwoofer could be the solution you've been searching for. You will be pleasantly surprised if you believe that a shallow-mount subwoofer won't sound pleasant or will be too pricey.
You can acquire a subwoofer that sounds amazing and will last you for years of fun for less than one hundred dollars. In addition, reputable brands like Rockford Fosgate, Infinity, and Pioneer each provide various solutions that cost around $200 or less.
Similar to other types of stereo equipment, it might be challenging to figure out where to begin. There are numerous solutions available, many of which are worthy of consideration.
Shallow Vs Conventional Subs
Like with a conventional subwoofer or any other component of your stereo system, is whether or not the shallow-mount subwoofer will complement your current stereo and work with the space you have available. A tape measure and your ear are both valuable tools in this situation.
The price of shallow-mount subwoofers is comparable to the price of standard subwoofers. You can get one for less than fifty dollars, but decent, affordable ones cost between eighty and one hundred dollars. Subwoofers with a short mounting depth of the premium grade will run you around $200.
The installation depth for most subwoofers should be between six and eight inches. In most cases, a shallow subwoofer will need a space that is half as deep or between three and four inches.
Subwoofers that are shallow-mounted weigh less and take up less room than traditional subwoofers, yet they provide the same sound quality. Because of this, they are perfect for use in compact vehicles and pickup trucks that do not have a lot of space for a large subwoofer.
