The IS213 subwoofer is an ultra-compact, 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, 13" ND13-S Kevlar(c) Neodymium drivers utilizing Adamson's Advanced Cone Architecture. 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 SpeakonTM NL4 connectors, or barrier strips available upon request. The IS213 ships with removable handles for easy handling, while allowing it to fit in tight spaces when the handles are removed, as well as rubber scuff guards on top and bottom that mate with additional IS213s for vertical stacking.
