QSC E115 15-Inch Passive Speaker

The E115 is specifically designed for applications where you need a full-range speaker that delivers high power and an authoritative low-end.

The E115 from QSC is a 15” passive speaker. Part of the E Series family of loudspeakers, this trapezoidal, two-way speaker uses a 15”, 500W, diecast aluminum frame woofer with a 3.5-inch voice coil. A 2.8” compression driver attached to the 75° DMT^TM waveguide ensures great coverage of your audience—even those seated way at the back of the room!

More about QSC’s E Series Loudspeakers

The E Series family of passive loudspeakers from QSC offers robust construction, trusted reliability, and impressive sonic performance that makes this line of speakers ideal for sound reinforcement in entertainment applications including live performance, DJ and dance music, stage monitoring, karaoke, and event productions. E Series is made up of 6 models that are optimized for creating a complete E Series Entertainment System, but they are also compatible with any quality, professional power amplifier.

Achieve a higher level of audio performance with QSC’s finely-tuned digital signal processing (DSP). E Series loudspeakers are further enhanced when paired with QSC GXD or PLD amplifiers or with a QSC TouchMix™ digital mixer by taking advantage of the onboard DSP and factory-tuned presets. (Amps and mixers are sold separately.) Each member of the E Series is constructed of rugged plywood with a black, textured paint finish. Their durable grilles are lined with foam to protect the woofers and enhance aesthetics.

The E110, E112, and E115 models are equipped with an all-metal, dual-angle, 35mm socket that allows them to be mounted vertically on a pole or angled down by 10° for better audience coverage. Use the E Series Yoke or M8 eyebolts to customize your mounting setup. Input connections include dual NL4 as well as screw terminal receptacles. The larger E215 and E218sw models feature ergonomic, aluminum handles to ease portability.
