Martin Audio's SX218 Black is a subwoofer designed to provide a solid, controlled foundation for any professional broadcast system. Equipped with two 18-inch long-excursion drivers, it delivers deep, punchy bass with an extended response down to 35 Hz. This design enables the energy of low frequencies to be reproduced with precision, while maintaining excellent signal clarity.

Designed for demanding environments, it combines power and control. Its ability to reach high levels of pressure makes it a relevant choice for concerts, events or fixed installations requiring constant sound impact, even at high levels.

The multi-ply plywood cabinet ensures robustness in the face of transport and intensive use. The bass-reflex ports on the front panel ensure effective bass diffusion while limiting unwanted air noise, guaranteeing a clean, homogeneous sound.

When it comes to integration, the SX218 offers flexible installation thanks to its numerous mounting points and M20 base, making it easy to combine with full-range speakers. It can also be configured in cardioid mode for better control of low-frequency dispersion.

Reliable and versatile, it is equally suited to touring configurations and permanent installations, providing a stable and coherent bass base for the system as a whole.
