QSC E115 無源喇叭 (passive speaker)

Product Details

The E115 is a trapezoidal, two-way loudspeaker using a 15-inch, 500W, 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.
