TH118 | 18-inch 3,400-watt Passive Subwoofer

The TH118XL is a powerhouse subwoofer that is based on the acclaimed TH118 model, utilizing the same 18” long-excursion (LF) driver. However, the TH118XL takes the design to a whole new level with a longer Tapped Horn™ alignment, a patented Danley design that allows for the creation of physically small subs that are highly efficient, particularly in the low-end range, and nearly linear in their passband. The Tapped Horn™ design doubles the output ability of the driver element, combined with its high power handling, resulting in one of the most powerful subwoofers available.

The TH118XL is built to last, with 13-ply Baltic Birch used throughout the enclosure and encased in PolyUrea for protection from impact and atmospheric conditions. The subwoofer also comes equipped with multiple M10 rig points for easy installation in both install and touring settings. Additionally, the EW (Extreme Weather) variant is available for ultimate protection from the elements with high-density polyurethane panels impregnated with fiberglass fibers in place of standard plywood.
