What is the Martin Audio SX118 and what is it used for?
The Martin Audio SX118 is an 18-inch subwoofer built for professional live sound applications. Used units have been deployed across concert touring, experiential events and festivals, where consistent low-frequency output is required. It is typically combined with mid and high-frequency cabinets to form a complete system, and is regarded as a practical, road-worthy choice for demanding audio environments.
Who makes the SX118 and where does it sit in the Martin Audio range?
The SX118 is made by Martin Audio, a British loudspeaker manufacturer founded in 1971 and based in High Wycombe, England, now part of the Focusrite Group. The SX118 is a single 18-inch sub within a wider range that also includes double-18 configurations such as the SX218 and CSX218, allowing it to be scaled into larger line array packages alongside Martin Audio mid and high cabinets.
What is the SX118 commonly paired with in a professional system?
Used SX118 subwoofers are commonly paired with Martin Audio mid and high-frequency cabinets. One typical configuration combines SX118 units with XD12 mid and hi cabinets driven by an iKon amplifier, while larger line array packages have included SX118 units alongside WPM line array speakers, SX218 and CSX218 subs, and iK42 amplification, with the SX118 handling the low-end portion of the system.
How much does a used Martin Audio SX118 cost?
Used SX118 pricing varies depending on condition, age, whether the unit is sold individually or as part of a larger package, and what ancillary items are included. Units showing cosmetic wear such as surface scrapes will generally sit at a lower price point than those in nearer-to-new condition.

What should I check when buying a used Martin Audio SX118?
Inspect the cabinet for structural damage beyond light cosmetic wear such as surface scrapes, which are common on touring subs and do not affect performance.
