All About Proline-X Performance Series

The Performance Series is designed for those who want reliable bass performance without the complexity of a custom build. Each enclosure is CNC-cut, dado-joined, and finished with premium carpet for a professional look and airtight performance. These boxes are optimized for efficiency and accurate bass response.

Options include sealed designs for tight, controlled bass and ported models for louder, deeper extension. The Performance Series covers all popular sizes, including 10 inch, 12 inch, and 15 inch enclosures.

If you need more output and advanced features, explore our Professional Series. For compact installs, check out our Micro Series. The Performance Series is the sweet spot for powerful, accurate bass in everyday builds.
