What is a Subwoofer?

By Jessie Waite

If you are wondering what a subwoofer is and how it can elevate your audio experience, you’re in for a bass-tastic ride as we dive into the world of subwoofers.

So, what exactly is a subwoofer? In simple words, it’s a specialised speaker designed to reproduce low-frequency sounds, also known as bass. Subwoofers are like the heartbeat of your audio system, providing that deep, thumping sensation when a powerful bassline drops in your favourite song or when a cinematic explosion rocks the theatre.

Anatomy of a Subwoofer

Let’s break down the components and purpose of a subwoofer:


This is the heart of the subwoofer, responsible for creating those booming bass notes.


The driver is housed in an enclosure designed to maximise the efficiency of sound production.


Subwoofers have built-in amplifiers to ensure the bass is loud and clear.


A crossover directs the low-frequency signals to the subwoofer, ensuring it handles the bass while other speakers focus on higher frequencies.

Subwoofer Sizes

Subwoofers come in various sizes, and the size matters when it comes to bass performance. The most common sizes are 8, 10, 12, and 15 inches. Larger subwoofers generally produce deeper bass, but they may not be suitable for smaller spaces or setups.

Subwoofer Placement

Now, where should you put your subwoofer for the best effect? The placement matters! Placing it in a corner can enhance bass response, while positioning it near the centre of a wall can create a more balanced sound. Experimentation is vital to finding the sweet spot that suits your room and listening preferences.

Now, imagine feeling the rumble of a spaceship taking off or the thud of a bass drum at a live concert – that’s the magic of a subwoofer!


So, what is a subwoofer? It is your ticket to experiencing the entire sound spectrum, from the subtlest bass notes to ground-shaking explosions. The secret sauce takes your audio and movie-watching experiences to a whole new level.
