The CS118 Subwoofer is the companion subwoofer to the CS7 & CS7p. Utilizing Adamson’s proprietary network platform, the CS118 employs a redundant MILAN scheme with the ability to daisy-chain networked audio between multiple sources, an analog XLR input and output, as well as on-board DSP and amplification. All features of the subwoofer are controlled and monitored through Adamson’s proprietary AI software.

The CS118 is front-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. This driver is mounted in an ultra-efficient 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 a male and female XLR connector, 2x etherCON connections and an in and through powerCON TRUE1 connection. The rigging system offers a wide variety of possible solutions.

Please refer to the CS118 User Manual for further information.
