Overview

Deeper, louder, stronger. With its two 18″ woofers with 3″ voice coils, the FO S218 is the most powerful subwoofer in the series and offers the deepest frequency response. The ideal complement for the FO 12 and FO 15 in stereo, 2.1 or surround systems. The subwoofer can be placed upright or on its side and offers a milled cable duct to the bottom, left and right for cable routing close to the wall. The front is protected by a full-surface grille, which is supported by solid reinforcements on the inside. This makes the FO S218 suitable not only for use in sports venues (for which a ball-impact resistance certificate in line with DIN 18032-3 is provided), but also for “wild” club and concert environments.
