The Martin Audio S218 is a high-output, dual 18-inch subwoofer designed to deliver deep, authoritative low end for live sound, touring and club installs. This listing is supplied as a set of two S218 subwoofers, each loaded with long-excursion 18-inch drivers featuring high-temperature 4-inch voice coils for reliability under sustained power. With a frequency range of 35–150 Hz (±3 dB), the S218 provides solid sub-bass extension and punch, while a nominal 4-ohm impedance makes it easy to extract maximum performance from modern amplifiers.
Rated at 1000 W AES / 4000 W peak per cabinet, the S218 achieves up to 136.5 dB continuous and 142.5 dB peak SPL, delivering headroom for demanding productions. The 320-litre birch plywood enclosure is finished in a durable black textured coating and fitted with dual Neutrik NL4 connectors for straightforward system integration. Whether ground-stacked under point-source tops or supporting a line array, the S218 excels in concert venues, theatres, clubs and events where impactful, controlled low frequencies are essential.
Ideal for professional rental and installation applications seeking powerful, consistent sub-bass performance.
