Overview
Big Bass Impact in a Compact Powered Package
The HS12 delivers low-frequency output from a robust 12-inch powered enclosure engineered for tight installs. Its all-aluminum frame is built for durability, while the integrated amplifier and onboard controls make it easy to dial in clean, controlled bass.
