Sound Reinforcement For Small And Medium-Size Venues

The Martin Audio SX218 Dual-Driver, Direct Radiating Subwoofer delivers very high output levels and superb transient performance with minimal distortion. With an operating range of 35Hz-150Hz ± 3dB, this loudspeaker 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 and suspension engineered for maximum linear excursion. The enclosure of this professional subwoofer 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. The Martin Audio 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.

  • 2 X 18” (460mm)/4” (100mm) Voice Coil, Long Excursion, Ferrite Magnet, Waterproof Cone
