Entertainment Venues ∙ Rental/Production ∙ HOW ∙ Mobile Performers
The E Series is a range of passive 
loudspeakers intended for sound reinforcement applications including live performance, 
DJ and dance music, karaoke and rental 
production. With continuous power ratings 
ranging from 300 to 800 watts, E Series is a 
great match for QSC GXD and PLD 
amplifiers. While E Series speakers will 
perform well with any professional amplifier, 
QSC has developed custom DSP tunings 
for GXD and PLD amplifiers that will 
produce extraordinary results. 
E Series consists of four models 
constructed of rugged plywood and coated 
in black, textured paint. Heavy-duty 
lined with foam provide protection for the 
woofers and a professional appearance. All 
three two-way 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 
reflections. Multiple mounting options using 
E Series accessories are supported. Input 
connections include dual NL4 as well as 
screw-down terminals. 
E10
The E10 is a compact, two-way 
loudspeaker featuring a 10-inch, die cast 
frame woofer with a 2.5-inch voice-coil 
housed in a multi-purpose enclosure that’s 
at home in stage monitor or main PA 
deployment. It incorporates QSC DMT 
(Directivity Matched Transition) design with a 
wide 85° coverage. When used as a stage 
monitor, the E10 is angled up at a deliberate 
55° angle allowing it to be placed near the 
performer when used on a crowded stage.
E12
The E12 is a trapezoidal, two-way 
loudspeaker featuring a 12-inch die cast 
aluminum woofer with a 3-inch voice-coil. 
The 15 mm, 11-ply enclosure provides 
enough volume to deliver solid lowfrequency extension down to 50 Hz, making 
it an excellent choice for applications in 
which space or budget
 preclude the use of 
grilles 
™
a subwoofer. The DMT coverage angle of 
85° is ideal for most medium and mediumlong throw applications.
E15
The E15 is a trapezoidal, two-way 
loudspeaker featuring a 15-inch, 500 W, die 
cast aluminum frame woofer with a 3.5-inch 
voice coil. It is intended for use when highpower and powerful low-end are needed 
from a full-range loudspeaker. A massive 
2.8-inch compression driver attached to the 
75° DMT waveguide ensures that even the 
furthermost listeners will hear clearly.
E18SW
The E18SW is a high-performance direct 
radiating subwoofer with a single, 800 W, 
18-inch, aluminum frame woofer. It is 
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.
PLD, GXD and TouchMix Tunings
E Series loudspeakers will perform very well 
with any quality, professional power amplifier. 
However, by taking advantage of the 
complete QSC entertainment system, more 
performance and options become available. 
Today’s powered loudspeakers rely on finely 
tuned digital signal processing (DSP) to 
achieve a higher level of performance. When 
used with QSC PLD or GXD 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 subw 
dance music and karaoke.
