Product Overview

Take your system's frequency range down to 35Hz for low end they can feel and hear with the SX218 2 x 18" high-performance 2000W subwoofer system from Martin. A compact enclosure and its direct radiation operating principle allow the SX218 to deliver its powerful bass where space is a concern or the equipment must remain out of sight.

The design of the 18" drivers coupled with eight reflex ports make the SX118 extremely efficient while maximizing output and reducing distortion to deliver signature Martin quality audio. With a stunning transient response, the SX218 produces tight, defined low end with minimal distortion.

Multi-laminate birch ply with a rugged poly coating form the cabinet for the dual 18" speakers that are protected from the outside world by a Zintec (zinc-coated steel) grille to ensure reliability show after show. The tour-grade enclosure features twin grab handles, skids, flying inserts for installation, and a threaded socket for pole-mounting point source loudspeakers. Casters for the SX218 must be purchased separately.

Your SX218 can be fully weather resistant and suitable for permanent outdoor installation with the addition of the WRKIT input board cover (sold separately).
