Deeper, louder, stronger. With its two 18 woofers with 3 voice coils, the FOS218 is the most powerful subwoofer in the series and offers the deepest frequency response. The ideal complement for the FO12 and FO15 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 FOS218 suitable not only for use in sports venues (for which a ball-impact resistance certificate in line with DIN18032-3 is provided), but also for wild club and concert environments.
