Why Do You Need a Subwoofer ?

Why Do You Need a Subwoofer ?

Subwoofers are speakers designed to produce only the lowest frequencies in a range of audio frequencies. As such, it can fill one’s room with those deep bass sounds that smaller coaxial speakers cannot produce. In many cases, a subwoofer can be used as a standalone speaker for a computer or a home theatre system without any need for rear speakers.

When you determine what type of receiver you own and how many channels your receiver has, make sure that you choose a matching subwoofer as well. For example, some 3-channel receivers will require separate 2-way satellite speakers and a separate powered subwoofer with a built-in amplifier.

A subwoofer can be considered as a smaller version of the main speaker. It is typically more prominent and has two essential components: the speaker (the actual transducer, which converts electricity into sound) and an amplifier (a power amplifier). Some people think that adding a separate subwoofer helps them save money, which isn’t true because buying only the speaker will also work fine without buying all those extra wires and connectors – not to mention that it’s much cheaper this way.

One might simply use their existing speakers for bass reproduction, but this is not recommended because most speakers do not emphasize low frequencies enough. Instead, speakers designed specifically for this purpose (subwoofers) ensure that low frequencies will be produced, and they can also help you get the most out of your system.

Sometimes, a subwoofer might also be used with speakers to improve their bass response; however, not all speakers need additional support in this regard. In such cases, one should check whether its sound output is even across the entire frequency band rather than just at one particular frequency band or “octave”.

Why do you need a subwoofer?

  • To complement your speaker’s weak bass response.
  • To get the most out of your new speakers without having to spend too much money on full surround sound speakers, yet still achieve realistic sounds with deep basses by supplementing its output with an additional subwoofer only.
  • The quality of the main speakers is not good enough, and the best option is to substitute them with good subwoofers.
  • For better quality control of your sound by having independent controls over bass response, perhaps you might want more bass in some situations but less in others (for example, listening to music or watching a movie).
  • The speakers are placed too far apart, and you need an additional speaker to bridge that gap between them for better frequency distribution because the drivers are not pointed at where listeners are seated. This problem can be solved without even buying a subwoofer! More information about this is here.
  • Cleaner generally sounds when it comes to boosting volume levels – especially if one’s receiver isn’t capable of handling loud volumes well in general


If you’re in the market for speakers, passive subwoofers can offer a simple and affordable solution. Passive units use external amplifiers, which must have enough power to sustain bass effects through your speaker size – this will determine what kind of amp is required! 

Active ones utilize their own AC source, so they don’t need any additional equipment, but there are also some limitations on how much volume or frequency range these devices cover because it relies heavily upon its ability to produce sound waves that travel outside itself.

So, you’re looking to buy a new subwoofer but don’t know what the heck “crossover” is? Subwoofers aren’t concerned with sound distribution and speakers; they only care about frequencies.

The circuit that decides which ones go where, includes everything from 80Hz up through 100HZ. Those below or around this range will get funnelled into your woofers while higher notes stay intact for other parts of the system, like tweeters and capsules and drivers in general use throughout an audio setup.


Ported Subwoofers:

Ported Subwoofers are designed to produce strong bass frequencies. They are usually larger and have a low-frequency driver inside an enclosure with a vent or port that allows the sound waves to flow in and out of the cabinet. These drivers operate at low frequencies, allowing them to vibrate more, which produces deeper sounds. This type of subwoofer works best when placed against a wall or enclosure because this increases its efficiency by “amplifying” the sound waves produced by these speakers.

Active Subwoofers are powered, so they do not require any amplification device for them to work correctly. The power needed is supplied separately from the speaker itself without compromising its performance. If budget is an issue, then building a subwoofer box could be an option.

Sealed Cabinet:

In a sealed cabinet, the bass only has one way. This can lead to less depth and complexity in sound as it travels through different parts of your home but will make up for this with greater clarity atonal highs, which means you’ll hear more detail than before.

Passive radiator:

Passive radiator subwoofers are an excellent way for people who want big bass sounds in small speakers. These passive radiators work by replacing the port. Which should allow more room-filling sound than what you would get from just one driver on its own. or even two voice coils wired together at different points within a single enclosure.

Front and Down Firing Types of Subwoofers

Front and down-firing refer to the placement of internal speakers within a subwoofer. Front-firing models will often have one speaker pointed forward while sound radiates out in all directions from it, as well as toward your feet if placed on something like shelves or stands which are elevated high enough for this effect (this would not be true with upward-facing drivers). Sound can also radiate up from below where there’s an extra bass output point located at around waist height – perfect if you want those low notes booming through your entire living room!

The downward-facing type design should work best when installing big bucks behind TVs because these types typically come equipped without cabinets blocking their path upwards towards couch potatoes who sit 2.

Bandpass Subwoofers

Bandpass speakers have two chambers that are separated. Usually, only one part of the divide will have a port that releases any radiation from the front cone to make it easier for bass frequencies within given ranges to come through cleanly with more natural sounding accuracy than other designs. The design is commonly used in professional live sound equipment such as line array systems or subwoofers cabinets designed specifically for car audio. But that’s not all, It can also be seen utilized by professionals who want their system output perfect at all times. Regardless if they’re playing an arena-sized stadium gig.

Horn Loaded Subwoofer

Horn-loaded speakers are often used in large venues where sound needs to go further and aim more precisely. They can be found as small, compact sizes despite the range of equipment required, given their sophisticated nature.

Choosing a Car Subwoofer

When it comes to car audio, the right subwoofer can make or break your system. These considerations include placement and size for best effect in cars with strange shapes that are cramped spaces inside an engine block on wheels! One type worth considering is powered active units, which provide more control while driving because they have higher power capabilities compared to 8″ models – but you’ll need a big enough enclosure if using this option, so don’t try reducing their volume level drastically either (although there will be no distortion).

But despite what some might say about more prominent being better when selecting speakers.

Placement of Car Subwoofers

The debate on where to place your car audio speakers has been going back and forth since it was just movies, but there are some general rules of thumb when deciding. Under-seat models will allow you more control over the bass while also letting other sounds come through clearly without being muddled by lower frequency packs; this can be handy if someone else in or near your vehicle might want to listen to (in which case they’ll need somewhere soft). On the other hand, putting them inside an open sedan trunk often leaves less room for cargo than desired (though not always), so finding something like Ibiquity’s PNP package helps solve both problems at once – giving everyone what they want out loud.

Combining it with Other Speakers

Subwoofers are speakers explicitly built to produce low frequencies, which are usually between 20-200 Hz. Depending on the design, they can be mounted in different ways, but one of the most popular is “downward-facing” because they emit sound downwards towards surfaces. Giving it an extra bass output point at waist height.

The bandpass subwoofer has two chambers that are separated while only having one port for releasing any radiation from the front cone, and this makes more natural-sounding accuracy than other designs without this feature would produce. This type of woofer is commonly used in professional live sound equipment such as line array systems or subwoofers cabinets designed specifically for car audio – but not limited there! It can also be utilized by professionals who want their system output perfect at all times regardless if they’re playing an arena-sized stadium gig.
