E Series

Passive Loudspeakers

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 grilles 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

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 subwoofers), stage monitoring, dance music and karaoke.
