The QSC E118SW is a single 18-inch passive subwoofer designed to add deep, powerful low-frequency extension to QSC E Series and other full-range systems. It is driven by external QSC amplification with the matching E Series subwoofer preset, pairing a long-excursion 18-inch driver with a 4-inch voice coil in a tuned enclosure for high output down to 32 Hz. Rugged tour-grade construction and pole-mount provisions make it a strong foundation for mobile production, live sound, and installed applications that need serious bass.
