Compact & Efficient
Ideal for small hatchbacks, compact sedans and under-seat installs. Compact enclosure, fast and accurate bass, lower power requirements and easier installation.
Is a 15-inch subwoofer better than a 10-inch? Not necessarily. Size is only one part of the equation — the enclosure, amplifier, tuning and installation matter just as much. Here's how to choose the right one for your vehicle.
A subwoofer is designed to reproduce the lowest frequencies in music — typically between 20Hz and 80Hz. Without a dedicated subwoofer, your door speakers are forced to reproduce frequencies they weren't designed to handle, reducing overall sound quality.
Adding a subwoofer doesn't just improve bass — it allows the rest of your speakers to perform more efficiently, creating a fuller and more balanced listening experience.
A larger subwoofer generally has the potential to move more air, producing deeper bass and higher output. But bigger also means larger enclosure requirements, increased power demands, more boot space used and greater weight.
A well-designed 10-inch subwoofer can easily outperform a poorly installed 15-inch model. Choosing the correct size is about matching the subwoofer to your vehicle and listening style — not simply buying the biggest option available.
From 8-inch to 15-inch, here's how the most common sizes stack up against each other — and who each one suits best.
Relative diameter — bigger cones move more air, but need more space and power
Ideal for small hatchbacks, compact sedans and under-seat installs. Compact enclosure, fast and accurate bass, lower power requirements and easier installation.
An excellent balance of sound quality, bass output, installation flexibility and space. Great for daily drivers, SUVs, double-cab bakkies and family vehicles.
Deep bass, strong output and wide product selection. Suits hip-hop, EDM, rock, long-distance touring and customers wanting a premium upgrade.
Enormous low-frequency output, but needs significant enclosure space, powerful amplification and careful tuning. Aimed at enthusiasts rather than everyday drivers.
The enclosure has a major influence on how a subwoofer performs. A sealed box controls the air behind the cone for tight, accurate bass. A ported box lets air escape through a tuned vent, adding output and efficiency at the cost of some precision.
Sealed: controlled and precise. Ported: louder and deeper, with a tuned vent for extra output
Ideal for listeners who enjoy balanced, musical bass.
Popular with customers who enjoy louder systems and bass-heavy music.
Contain a built-in amplifier in a compact enclosure with simple installation — ideal for customers wanting a discreet upgrade.
Require an external amplifier, but offer greater upgrade flexibility, higher performance potential, wider product choice and better long-term scalability. See our guide on which amplifier you need.
Different vehicles have different space limitations. Here's a general starting point.
8-inch or 10-inch subwoofers often provide the best balance.
10-inch or 12-inch systems are the most common choice.
12-inch subwoofers offer outstanding performance while leaving usable cargo space.
Space behind the rear seats can be limited — slimline or custom enclosures work well. See our Toyota Hilux upgrade guide.
Avoid these common errors when choosing a subwoofer.
Choosing the right subwoofer is about creating a balanced audio system that suits your vehicle and the way you enjoy music. Bring your vehicle to our Newton Park workshop and we'll help you get the combination right.
