Martin Audio SX118 18" Passive Subwoofer

The SX118 is a compact direct-radiating subwoofer with a single 18" (460mm) long-excursion driver on a 4" voice coil and a waterproof cone. Built in a tour-grade plywood enclosure with a protective grille and flying inserts, it suits fixed installs, touring rigs and outdoor stages alike, delivering substantial low end from a cabinet that a single person can still handle.

It handles 1000W AES (4000W peak) at 8 ohms and reaches 138dB peak, with response from 47Hz (-10dB at 41Hz). Two NL4 connectors handle input and link, and optional castors make it easy to roll in and out of a venue. It is available in black or white textured finish.
