Description
The Martin Audio SX118 is a compact high-performance direct-radiating subwoofer designed to extend system low-frequency response down to 47Hz while delivering exceptional bass output from a relatively compact enclosure. Featuring a powerful 18-inch long-excursion driver with a waterproof cone and high-power 4-inch voice coil, the SX118 combines impressive low-frequency extension, high SPL capability, and deployment flexibility. Suitable for both portable and installed sound systems, it can be used in omnidirectional configurations or paired for cardioid subwoofer applications where improved low-frequency control is required.
