QSC E118SW The QSC E118SW is a passive subwoofer that features a single, 800W, 18-inch, aluminum frame woofer. It's been 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. Price is for a single QSC E118SW.Specifications Configuration: 1 x 18-inch, subwoofer, non-powered Frequency Response (-6 dB): 37 Hz to 230 Hz Frequency Range (-10 dB): 32 Hz to 230 Hz Power capacity: continuous/peak: 800 W / 3200 W Sensitivity: 98 dB, 1 W @ 1 m Coverage Angle: N/A Output (peak SPL @ 1 m): 133 dB Nominal Impedance: 4Ω Cross-over: Recommended 80 – 120 Hz LPF Input connectors: 2 x NL4, 1 x barrier strip Dimensions (WxHxD): 590 x 616 x 605 mm Net weight: 43 kg / 95 lbs Shipping weight: 48 kg / 106 lb
