QSC E112 – 12-Inch 2-Way Passive Loudspeaker (Black)

Product Overview

The QSC E112 is a 12-inch, two-way passive loudspeaker in a trapezoidal cabinet, built for live performance, DJ and dance music, karaoke, and event production. It requires external amplification and is part of QSC's E Series Entertainment System.

An 85° DMT coverage pattern and a dual-angle pole socket make it a flexible main or fill loudspeaker for medium and medium-to-long-throw applications.

Product Description

The E112 pairs a 12-inch woofer with a 1-inch compression driver for a frequency response of 64 Hz to 20 kHz (-6 dB) and a peak SPL of 128 dB. It requires an amplifier with a minimum of 400 W continuous (1600 W peak). QSC recommends a DSP speaker processor or a DSP-equipped amplifier — such as QSC GXD or PLD amplifiers, or TouchMix digital mixers — to set crossovers, limiting, and EQ, with factory presets for live reinforcement (with and without subs), stage monitoring, dance music, and karaoke.

The 15 mm, 11-ply enclosure delivers Directivity Matched Transition (DMT) coverage of 85° for most medium and medium-to-long-throw applications. An all-metal dual-angle 35 mm socket allows vertical pole mounting or a 10° down-angle to improve audience coverage and reduce rear-wall reflections, with E Series Yoke or M8 eyebolt mounting options (sold separately). Inputs include dual NL4 and screw-terminal receptacles.

For larger coverage, see the 15-inch QSC E115; for low end, the QSC E118SW.
