The IS219 subwoofer is a high-powered subwoofer intended to be used in ground stack configurations and to fit in compact spaces.  The enclosure is loaded with two light weight, long excursion, 19” SD19 Neodymium drivers, made with Kevlar® utilizing Adamson’s Advanced Cone Architecture, and a dual 5” voice coil for exceptional power handling. It is mounted in an ultra-efficient front-loaded enclosure, designed to reproduce clean, musical low frequency information.

The cabinet construction uses marine grade birch plywood as well as aircraft grade steel and aluminum, and is equipped with two front and back Speakon™ NL4 connectors, or barrier strips available upon request. The IS219 ships with removable handles for easy handles, while allowing it to fit in tight spaces when the handles are removed.
