Every Proline X enclosure is manufactured in our Tullahoma, Tennessee facility using materials and construction methods that most enclosure brands don't touch.
48.5 lb/ft³ density and 200 psi internal bond strength, the highest-grade MDF available for enclosure construction.
Full coverage on materials and construction defects. We stand behind every enclosure we build.
Internal volume, port tuning, and cabinet dimensions are spec'd to each driver diameter, not a universal fit applied across sizes.
