The E118sw is a high-performance direct radiation subwoofer with a single, 800W, 18-inch, aluminum frame woofer. It’s designed to

produce crushing low-end for live performance with kick-drum and bass in the PA or for high-level, high-energy dance music. 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-ohm impedance means that a single woofer can be optimally powered

by a less expensive amplifier.

E Series loudspeakers will perform very well with any quality, professional power amplifier – but by taking advantage of the complete E Series

Entertainment System, more performance and options are available. Today’s powered loudspeakers rely on finely tuned digital signal processing

(DSP) to achieve a higher level of performance. 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), stage monitoring, dance music and karaoke.
