What is a Subwoofer & How Does it Works?

A key component of your home theater’s sound system is the subwoofer.

It widens the soundstage and adds a new dimension to your music-listening experience.

By adding a subwoofer to your audio system, you can experience better-defined bass notes in addition to being capable of producing sound at volumes that surpass what’s usually produced by your main speakers.

Even though the main purpose of the subwoofer is to enhance the bass, there’s more than that going on. Here is a detailed discussion of this exciting piece of equipment with some facts that will excite you.

What is a Subwoofer?

A subwoofer is a special or unique speaker that produces low-frequency sound waves. The lower the frequency, the deeper and more powerful the bass will be.

A subwoofer is a device that helps you hear the bass in your music. It can be used for movies and video games, but it’s also very useful for listening to music. Also, it uses an amplifier to boost the volume of the sound it produces.

The sound it produces can fill in the gap between your speakers and the level they produce when they are playing at their maximum volume.

Additionally, subwoofers have been around since the early days of home entertainment systems. They are used in movie theaters and concert halls to enhance the deep bass sounds from large speakers or woofers.

But What is a Bass?

Bass frequencies are typically below the range of human hearing, and vibrations produce sounds from a driver in front of a passive radiator.

The bass in most songs is usually very low, sometimes below 100Hz, so if you’re listening to a song with heavy bass content, like dance hip-hop, you might be able to tell if it has been recorded using subwoofer technology because of its presence in the mix.

Types of Subwoofer

The type of subwoofer you choose depends on the environment you’ll be using it.

There are two main types of subwoofers there; active and passive.

Powered Subwoofer

Powered subwoofers have a built-in amplifier that helps them produce the sound they’re supposed to. Amp creates and sends the signal to the woofer and can be driven by a signal from your receiver or preamp, or it can be self-powered, which means you don’t need any additional equipment to get started.

This can be particularly helpful when you’re using them in a large space because they’ll play at a high volume without using too much power.

Besides, powered subwoofers are great for larger systems with multiple speakers because they require less space than passive subwoofers and won’t require you to add another amp to your setup.

Powered subwoofers also tend to be more expensive than passive ones, but they do offer an advantage over their passive counterparts. They can handle higher levels of an input signal (such as from your stereo), which means that your music will sound louder and clearer than it would with passive subs.

Passive Subwoofer

Passive subwoofers do require an external amplifier that should be compatible with the driver power rating to perform at its maximum potential. Also, they rely on the volume of their speaker enclosure to produce the bass frequencies.

While this type of subwoofer is more affordable than the active one, it still requires power from an outlet- which means you’ll need to make sure your power supply doesn’t run out of juice before your music does!

Moreover, passive subwoofers are often used in small home setups because they are easy to install and don’t require any additional equipment besides an enclosure for mounting them in your room.

What does a Subwoofer do?

In simple words, a subwoofer is a device that helps you hear the bass in your music.

Subwoofers have many uses, from making your music sound better to helping you better understand the lyrics of songs you listen to.

Subwoofers are so important because they allow you to hear sounds that would otherwise be drowned out by other noises in your room or home theater setup.

Also, subwoofers are great for filling out a room with additional sound, but they also create effects like a punchy bass line or deep rumbling that you can’t get from your other speakers alone.

They can be used to create an immersive experience at home or in the car, and they come in all shapes and sizes from small speakers that sit on your desk or bookshelf to large ones that sit under your seat in your car.

How does a Subwoofer Work?

Subwoofers are the low-frequency drivers in your home entertainment system. They help you hear the bass coming from your TV, stereo, or other audio devices.

To make a subwoofer work with your other devices, like a TV or stereo, you need to connect them using the right cables and connectors.

Connecting Subwoofer to Other Devices

The process of connecting subwoofers to other devices is simple:

You can connect your subwoofer to any audio device using an RCA or optical cable. Despite the model and size, subwoofers include a variety of input and output collections to make the device versatile to connect with any possible device.

An RCA cable uses two small gold plugs that go into one end of the subwoofer and another end into a corresponding jack on your TV or home theater system.

On the other hand, an optical cable has three separate wires: red, yellow, and white that needs to insert into their respective jacks on the back of your TV or stereo system’s receiver input.

Connect Subwoofer Wirelessly

Many subwoofers, especially mid-range and high-end ones, come with WiFi and Bluetooth connections to create a stable connection with a receiver without any cable mess.

Bluetooth helps with wireless connection with supporting devices, and WiFi lets you stream music from online music channels and expand your soundstage.

Make the Device Functional

Once you connect a subwoofer with its respective receiver, you can utilize the built-in buttons or use a remote control/application (if your model comes with any) to enable its functionality.

Once you turn on the device, create a connection, and play the music, you can adjust the sound level, bass quality, and frequency range utilizing the given control levels.

What does a Subwoofer do for a TV?

Subwoofers can be the most exciting piece of audio equipment in your home.

After connecting to a TV, a subwoofer can enhance the bass and sound quality of the TV speakers, as well as provide a richer listening experience for your friend and family.

A subwoofer can be used with other audio components, such as a receiver or amplifier, to create a more powerful and accurate sound system. When you watch TV and want to turn up the volume, the subwoofer does something else: boost your TV speakers’ bass and sound quality.

It is also used to boost sound quality when watching movies or playing video games on your TV. In such a case, you must have a subwoofer with enough power to produce an audible bass response without being too loud for your neighbors.

What does a Subwoofer do for a Soundbar?

The bass is the bass.

It is the low, deep, booming sound you hear when you turn up the volume on your music or video. But what about the rest of your audio? That’s where your subwoofer comes in.

Your soundbar can’t produce these low frequencies (the ones that make you feel like the walls are shaking) by itself. It needs something to help it out a powerful device that amplifies low-frequency sounds and sends them to your headphones or speakers evenly through the air.

A subwoofer is exactly that: it reproduces lower-frequency sounds so they can be heard independently of other parts of your music or movie tracks.

Now you must think, many soundbars also include a built-in woofer to focus on the lower end of the frequencies. Yes, subwoofers like that exist and do a pretty good job with bass.

However, a separate subwoofer can lower the burden of other speakers and let the soundbar speakers (front or downward-facing) focus on the upper and mid frequencies to create perfect harmony and enrich the sound.

Sum Up

A subwoofer is a final link in your music system. It amplifies the speaker’s sound by creating a vibration that travels through the air and produces bass notes that are heard during regular music listening.

This article briefly discusses what is a subwoofer, how it works, and its uses and contributions to sound systems. Make it a part of your home theater system, and enjoy precise, hitting, and accurate bass notes.
