About the Martin Audio SX218 2x18" High-Performance Subwoofer System

With an operating range of 35Hz-150Hz ± 3dB, it houses dual 18” long-excursion (460mm)/4” (100mm) voice coil drivers with water-resistant cones and triple roll surrounds. Each driver is rated to handle 1000 watts AES and has a magnet structure which is suspension engineered for maximum linear excursion.

The enclosure is constructed from multi-laminate birch ply and finished with a durable polyurea coating. Eight reflex ports provide a large frontal area to reduce turbulent air noise, and a perforated steel grille protects the drivers from damage. SX218 features a M20 pole mount insert for added versatility in deployment.

The product is supplied as standard without cabinet wheels, but they are available as an accessory.

By adding the input board cover accessory, SX218 is fully weather resistant and suitable for permanent outdoor usage.
