What is free air bass?

Free air bass refers to a type of subwoofer installation that does not require the use of an enclosure or box. This means that the subwoofer is mounted in an open space, such as a trunk or door panel, without any type of surrounding structure.

This type of installation is often used in vehicles where space is limited and an enclosed subwoofer may not be feasible. Free air bass can provide a clean and accurate bass response, but it requires careful consideration of the installation location, the subwoofer itself, and the vehicle's acoustics.

Additionally, free air bass typically requires a subwoofer specifically designed for this type of installation. These subwoofers typically have a stiffer suspension and a specific design to ensure optimal performance in an open-air environment.
