Martin Audio SX218 Subwoofer

Martin Audio SX218 Subwoofer

The SX218 delivers very high output levels and superb transient performance with minimal distortion.

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.
