Product description:

S218 is a next-generation touring subwoofer designed to bring the ultimate low-frequency reinforcement. Easy to install, reliable, and designed to withstand the most challenging transportation and usage conditions.

The dual 18” vented box - delivering an unparalleled 146 dB peak SPL- is compatible with MAG’s Uni-Preset technology. This feature allows the S218 to be seamlessly coupled with every MAG Audio speaker straight out of the box.

The SilentFlow vent port technology employs a unique design to minimize air noise at high levels by utilizing a specialized shape that reduces any turbulence and enhances low-frequency efficiency.

The S218 was made with absolute touring and rental utility in mind: it can be flown as an array using integrated mounting hardware. Available for both standard and cardioid use.

For ground installation, the convenient stacking rails allow for quick cabinet positioning while preventing accidental side movement. The S218 can even be stacked in a vertical position to minimize the occupied space, with side interlocking feet making the stack extremely solid and easy to assemble.

Main features:

• 2500W nominal power

• 2x18” woofer with 4” voice coil

• 146 dB Max SPL
