E115
The E115 is a trapezoidal, two-way loudspeaker offering robust construction, trusted
reliability and overall sonic performance beyond expectations. Featuring a 15-inch die-cast
aluminum frame woofer with a large 3.5-inch voice coil that can handle 500 W of
continuous power, it is intended for use when high-power and authoritative low-end are
needed from a full-range loudspeaker. A large format 2.8-inch compression driver attached
to the 75° DMT waveguide assures that even distant listeners will be well covered.
E Series Loudspeakers
The E Series is a range of passive loudspeakers offering robust construction, trusted reliability
and overall sonic performance beyond expectations. Intended for sound reinforcement in
entertainment applications, including live performance, DJ and dance music, karaoke and
event production, E Series loudspeakers will deliver outstanding results. Building on QSC’s
proven “Systems” methodology, the E Series loudspeakers’ performance is further enhanced
when paired with QSC’s GXD or PLD amplifi ers or with a QSC TouchMix digital mixer, and
taking advantage of the on-board DSP and factory-tuned presets. These presets support a
variety of applications including live sound reinforcement (with and without subwoofers), stage
monitoring, dance music and karaoke.
E Series consists of six models constructed of rugged plywood and coated in black,
textured paint. Heavy-duty grilles lined with foam provide protection for the woofers and
an elegant appearance. E110, E112 and E115 models are equipped with an all metal,
dual-angle, 35 mm socket that allows the speaker to be mounted vertically on a pole or
angled down by 10° to improve audience coverage and reduce rear wall refl ections. Multiple
mounting options using E Series Yoke or eyebolts are supported. Input connections include
dual NL4 as well as screw terminal receptacles. Additionally, E215 and E218sw models
feature ergonomic, aluminum handles to ease portability.
