Produces crushing low-end for live performance

QSC E118sw is a 18" passive subwoofer, high-performance direct radiation subwoofer with a single, 800W, 18-inch, aluminum frame woofer. A threaded, M20 pole socket and speaker pole are provided for sub/satellite use with any of the E Series two-way models. For portable applications it includes attachment points for four optional casters. The subwoofer’s 4-Ω impedance means that a single woofer can be optimally powered by a less expensive amplifier. When used with QSC GXD or PLD amplifiers or with a QSC TouchMix digital mixer, E Series loudspeakers can also take advantage of advanced DSP. QSC has developed E Series DSP settings for all three platforms. These settings support a variety of applications including live sound reinforcement, with and without subwoofers.


  • High output, professional quality sound with 800 W continuous power
  • Advanced digital signal processing tunings and options using QSC GXD, PLD amplifiers or TouchMix digital mixers
  • Rugged tour-grade textured paint
  • Foam-lined perforated steel grill
  • M20 pole socket and speaker pole are provided
