What is a free air subwoofer?
A free air subwoofer, also known as a “sealed subwoofer,” is a type of speaker designed to produce deep bass sounds without being housed in a traditional enclosure. This design allows the subwoofer to be mounted in a way that utilizes the air behind the speaker cone effectively, enabling it to create sound waves without needing to be in a dedicated box.
These subwoofers are commonly used in car audio systems, home theater setups, and sometimes in professional audio environments. Because they can operate without a box, they are often favored for their portability and adaptability in various installation scenarios.
How does a free air subwoofer work?
A free air subwoofer operates on the principle of using the surrounding air as part of its design. When the subwoofer cone moves, it displaces air, which in turn creates sound waves. In a free air setup, the back of the speaker cone is exposed to open air, which allows the sound to propagate more freely compared to conventional subwoofers that are housed in a box.
The key to effective sound production with a free air subwoofer is to carefully select the mounting location. Ideally, it should be in a location where the air can move unimpeded and where it can leverage the car’s or room’s design to enhance the overall sound quality.
