Active vs. Passive Subwoofers
Subwoofers, like loudspeakers, can be either passive or active. Active subwoofers have built-in amplifiers, making setup easier and ensuring better integration with the audio system. On the other hand, passive subwoofers use an external amplifier, providing more customization options and the potential for higher power handling. In both cases, the subwoofer needs a crossover to limit the frequencies of the audio signal sent to it. An active subwoofer already includes this crossover, while with a passive subwoofer, you might have to make the needed adjustments at the amplifier. Because active subwoofers require fewer connections and have all internal processing built-in, they are often a better choice for many audio systems.
Which Should You Choose?
When deciding between powered and passive speakers, consider the following:
Choose Powered Speakers If:
- You prefer a fuss-free system with minimal wires
