Martin 2 x 18" Dual Driver Direct Radiating Subwoofer WHITE

The marine-grade variant of the dual 18-inch direct-radiating subwoofer, finished in white and treated throughout for use in demanding outdoor or coastal installation environments. Combining the proven acoustic architecture of the SX series with enhanced corrosion-resistant componentry and hardware, this variant is the professional choice wherever exposure to salt air, humidity, or the elements is a consideration.

Built on the same multi-laminate plywood enclosure coated in durable polyurea as the standard model, the marine-grade treatment extends to all metalwork, connectors, and fixings to ensure lasting reliability in harsh conditions. Twin long-excursion 18-inch drivers with waterproof cones deliver the same 144 dB peak output as the standard SX218W, and the cabinet remains fully compatible with Martin Audio iKON amplifiers and VU-NET control software.
