WHAT IS A PASSIVE SUBWOOFER AND WHAT IS IT USED FOR?
If you are a music lover and like listening to your favorite music at full volume, you have probably already heard of subwoofers. A subwoofer is a loudspeaker designed to reproduce the lower frequencies of music, those that give intensity and depth to the sound. But do you know what a passive subwoofer is?
A passive subwoofer is a type of subwoofer without an internal amplifier. This means it requires an external amplifier to function. For this reason, these subwoofers need to be connected to an amplifier or separate sound system to function.
But why should you choose a passive subwoofer instead of an active one (i.e., with a built-in amplifier)?
One of the main reasons for choosing this type of subwoofer is flexibility, as it can be more easily tailored to your needs. Since they require an external amplifier, you have can choose one that best fits your needs and budget.
But how does a passive subwoofer work?
Basically, a passive subwoofer consists of a loudspeaker (the woofer) and a tuning system (the cabinet or case). The speaker is designed to reproduce lower frequencies, while the cabinet is designed to help “tune” the subwoofer so it can reproduce lower frequencies more effectively.
When you connect this type of subwoofer to an external amplifier, the amplifier supplies the audio signal to the subwoofer speaker. The passive subwoofer then reproduces the low frequencies of the music, creating a deep and enveloping sound.
In conclusion, passive subwoofers are a popular choice for those looking for quality sound and for those who want the flexibility to choose their amplifier. If you are considering buying one, make sure you choose a quality model and connect it to a suitable, powerful amplifier. This way, you will enjoy the best possible sound quality.
