The Martin Audio SX218 is a high-output dual 18-inch subwoofer designed for modern touring and installation duties where deep, controlled low-frequency extension is essential. This listing is for one subwoofer, loaded with two long-excursion 18-inch drivers featuring 4-inch voice coils, ferrite magnets and waterproof cones for dependable performance in demanding environments. Its direct-radiating design delivers authoritative, musical bass with excellent punch, definition and headroom, achieving up to 144 dB maximum output.
Engineered for the rigours of the road, the robust tour-grade plywood enclosure incorporates integrated flying inserts for flexible rigging and secure deployment. A dual 8-ohm configuration offers versatile system design options, making it straightforward to power with a wide range of professional amplifiers. The SX218 scales seamlessly from single-cab use to pairs, ground-stacked stacks or flown arrays, providing consistent coverage and coherent low-end coupling across larger systems.
Ideal for live sound reinforcement, festivals, clubs, theatres and high-impact fixed installations, the SX218 adds depth, authority and tight, musical low end to contemporary PA systems.
