Martin Audio SX218 Dual 18" Passive Subwoofer

The SX218 is a high-output touring subwoofer carrying two 18" (460mm) long-excursion drivers, each on a 4" voice coil with a waterproof cone, in a tour-grade plywood enclosure. It is the low-end anchor for larger Martin Audio systems, delivering the sustained deep output that concert, festival and large-venue rigs demand.

It handles 2000W AES (8000W peak) with each driver on its own 8-ohm winding, reaches 144dB peak and extends down to 30Hz (-10dB). Two NL4 connectors handle wiring, and optional castors make a cabinet of this size manageable to move. It is available in black or white.
