Advanced digital signal processing

QSC E115 two-way loudspeaker trapezoidal, two-way loudspeaker uses a 15-inch, 500W, die cast aluminum frame woofer with a 3.5″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° DMT™ waveguide assures that even distant listeners will be well covered.

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.

  • Titanium diaphragm for high fidelity and long life
  • Rugged tour-grade textured paint
  • Foam-lined perforated steel grill
  • Advanced digital signal processing tunings and options using QSC GXD, PLD amplifiers or TouchMix digital mixers.
