The S118 Subwoofer is the companion subwoofer to the S7.  The enclosure is loaded with a light weight, long excursion, 18” ND18-S Kevlar Neodymium driver utilizing Adamson’s Advanced Cone Architecture and a 4” 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 Speakon™ NL4 connectors. The integrated rigging system matches the rigging for the S7 and can be flown or stacked in the same array without the need for an adapter frame.
