The black QSC E118SW Passive Subwoofer is a high-performance direct radiation subwoofer, ideal for a variety of sound reinforcement applications such as live performances, DJ and dance music, karaoke, and event production. It requires an amplifier with a minimum of 800W continuous (3200W peak) to power its 18″ woofer, offering a frequency response of 37 to 230 Hz (-6 dB) and a peak SPL of 133 dB.

For optimal performance, QSC recommends the use of a speaker processor or a power amplifier with integrated DSP to set crossovers, limiting, and equalization. QSC’s GXD or PLD amplifiers, along with the TouchMix digital mixers, offer on-board DSP and factory-tuned presets for live sound reinforcement, stage monitoring, dance music, and karaoke.

Constructed with a rugged plywood enclosure, the E118SW is coated in black textured paint and features a heavy-duty grille lined with foam for added protection. It includes a threaded M20 pole socket and speaker pole for sub/satellite use with any of the E-Series two-way full-range loudspeakers. For portability, the subwoofer also includes attachment points for four optional casters.
