Active subwoofers: how they work and when to use them
What makes a subwoofer active?
An active subwoofer has an integrated amplifier built right into the speaker cabinet. This means that everything you need to reproduce deep bass is already inside – no need for an additional amplifier or compatibility concerns.
This design makes active subwoofers very convenient to use - just connect the power cord and audio cable and the device is ready to work. In addition, the integrated design saves space, as there is no need for a separate amplifier.
Most of these models have built-in crossover controls that automatically separate low frequencies from higher frequencies. This ensures that the subwoofer only reproduces the low frequencies it is intended for, which significantly improves sound quality.
Advantages of active subwoofers
With their direct connection and built-in controls, active subwoofers make it easy to tailor the sound to the acoustics of your room. In home theater systems, they connect directly to the subwoofer output of a receiver, or in computer audio systems, they connect to dedicated line or subwoofer outputs [1] .
Integrated controls such as volume, crossover frequency, and phase allow for precise sound matching with other speakers, especially useful when you need to tailor the sound output to room acoustics or personal preferences [1] .
Active models are ideal for modern compact audio systems. They not only take up little space, but are also easy to install, so they quickly and effectively improve sound quality.
Best Use Cases for Active Subwoofers
Given their advantages, active subwoofers are perfect for a variety of situations. They are especially useful when you need a quick and easy solution.
In home theater systems, active subwoofers work well with receivers from a variety of manufacturers, ensuring precise level and frequency matching with the main speakers [1] . For example, the Rogersound Labs Speedwoofer 10S MKII is a great choice, providing powerful and accurate bass for both stereo and home theater systems [1] .
They are widely used in professional PA systems to extend the low-frequency range and enhance the overall listening experience. [2] For example, QSC's KS Series active subwoofers, when used with K.2 Series active loudspeakers, demonstrate effective application in live sound systems. Such models have built-in crossover filters and equal gain modes that simplify system integration. [2]
AUTOGARSAS.LT offers a wide selection of active subwoofers suitable for both home audio systems and business premises or professional installations. Experts will help you choose the model that best suits the needs of your space and sound system requirements.
Passive subwoofers: how they work and when to use them
What makes a subwoofer passive?
Unlike active models, passive subwoofers offer more freedom in combining components . Their main feature is the lack of an integrated amplifier . They work only with an external amplifier, and the housing itself contains only the speaker element and crossover filter. This means that bass reproduction depends on the power of the external amplifier.
This solution allows users to choose the amplifier that best suits their needs, from small home systems to professional audio solutions. Additionally, by using separate components, it is possible to upgrade just the amplifier without replacing the entire subwoofer.
Some models are designed to make the most of the cabinet's acoustic design, ensuring better sound quality and longer life.
Advantages of passive subwoofers
One of the main advantages is the unlimited possibilities to customize the system to your needs . You can match the amplifier power to the speaker parameters, choose the right crossover type and even use multiple amplifiers for one speaker element.
Additionally, passive models are often a more cost-effective solution in the long run. If the external amplifier fails, it can be replaced, avoiding the need to replace the entire subwoofer.
Best Use Cases for Passive Subwoofers
Passive subwoofers are perfect for custom installations where it is important to tailor the system to the acoustics of the space. In home theater rooms where acoustics can be challenging, they allow you to precisely match the sound output to the specific characteristics of the room.
In professional sound systems – in concert halls, clubs or studios – passive subwoofers are often chosen for their reliability and the ability to adapt them to various situations. In car audio systems, they also provide a lot of flexibility. For example, the compact Gladen Audio GAMMA GS08-SLIM , offered by AUTOGARSAS.LT , is a great choice for cars where it is important to save space but not lose sound quality. This model can be combined with various amplifiers, taking into account the specifics of the car audio system.
AUTOGARSAS.LT specialists are ready to help you choose the most suitable passive subwoofer and corresponding amplifier, taking into account your space requirements, budget and desired sound quality. They also offer professional installation services to ensure optimal system performance. Below we will discuss how to choose the subwoofer that best suits your needs.
Active vs. Passive Subwoofers: A Direct Comparison
When choosing between active and passive subwoofers, the most important things to consider are their operating principle, installation complexity, and price. The final decision depends on your needs and priorities.
Active subwoofers with built-in amplifiers are easier to use – they can be quickly connected and started using. Passive models require more preparation, but provide greater freedom in creating individual sound systems.

How to choose the right type of subwoofer
Purpose and place of use
When choosing a subwoofer, it is important to consider where and how you plan to use it. Active models are usually recommended for home theater systems , as they are easy to connect to AV equipment, such as a soundbar or compact stereo system. Meanwhile, for cars or professional solutions , such as concert halls or clubs, passive subwoofers are more often chosen, as they allow the use of an external amplifier, which provides more flexibility.
In car audio systems, passive subwoofers are more practical because they allow you to tailor the amplifier to the car's acoustic environment and space constraints. Active models may be less effective here because there is no constant power source in the car.
In professional environments where a powerful and adaptable system is required, passive subwoofers become a more attractive option. They allow for easier replacement or upgrade of individual components, ensuring durability and ease of maintenance.
Space and installation features
The space where you plan to use the subwoofer is also an important factor. In small rooms , such as apartments or offices, active subwoofers are more practical because they save space - they do not require an additional amplifier. Compact models are perfect for placing under a sofa or next to a TV.
In large spaces , such as purpose-built sound rooms, passive subwoofers can offer more options. The amplifier can be installed in a well-ventilated area, and the speakers themselves can be placed in optimal points, ensuring the best sound dispersion.
Budget and personalization options
Another important criterion is your budget and your need to customize your system. Active subwoofers are ready to use right out of the box, so their initial cost is often lower. Passive models, on the other hand, require an additional amplifier, but give you more options for upgrading your system over time. For example, you can change the amplifier, add additional channels, or experiment with sound settings.
If you plan to expand or upgrade your sound system in the future, passive solutions may be a better choice. However, if simplicity and quick installation are your priority, active subwoofers will be a more convenient option.
