QSC E115 The QSC E115 is a two-way loudspeaker that features a 15-inch, die cast aluminum frame woofer with a 3.5-inch voice coil. It is intended for use when high-power and authoritative low-end are needed from a full-range loudspeaker. A 2.8” compression driver attached to the 75° DMTTM waveguide assures that even distant listeners will be well covered. 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.Specifications Configuration: 1 x 15-inch, 2-way, non-powered Frequency Response (-6 dB): 55 Hz – 20 kHz Frequency Range (-10 dB): 43 Hz – 20 kHz Power capacity: continuous/peak: 500 W / 2000 W Sensitivity: 97 dB, 1 W @ 1 m Coverage Angle: 75° conical DMT Output (peak SPL @ 1 m): 130 dB LF Driver: 381 mm (15-inch) driver with 89 mm (3.5-inch) voice coil HF Driver: 38 mm (1.5-inch) exit, 71 mm (2.8-inch) voice coil, compression driver Nominal Impedance: 8Ω Cross-over: Full-range only 1.55 kHz Input connectors: 2 x NL4, 1 x barrier strip Dimensions (WxHxD): 16.5 x 28.2 x 17.5 in Net weight: 31 kg / 68 lb Shipping weight: 34 kg / 75 lb
