Overview

The QSC E112-BK is a professional 2-way passive loudspeaker built around a 12-inch woofer housed in a die-cast aluminum frame, paired with a high-frequency compression driver for clear vocal and instrument reproduction. Rated at 400 watts continuous power handling, it is designed for live sound reinforcement, stage monitoring, and fixed installations where reliable, high-output audio is essential. The 85-degree conical coverage pattern, achieved through QSC's Directivity Matched Transition (DMT) design, ensures consistent sound quality whether listeners are directly on-axis or off to the side, reducing the need for excessive EQ adjustments across the venue.

Built to withstand professional use, the E112-BK features a 15mm, 11-ply wood enclosure finished in a tour-grade textured paint that resists scratches and scuffs. A foam-lined perforated steel grille protects the drivers from impact while maintaining acoustic transparency. The dual-angle pole socket allows the speaker to be tilted downward when elevated on a stand, directing sound more precisely at the audience. For permanent installations, an optional U-Style yoke and M8 rigging kit provide secure mounting options. When paired with QSC GXD or PLD amplifiers, or TouchMix digital mixers, the E112-BK unlocks speaker-specific DSP tunings that optimize crossover points, EQ, and limiting for enhanced performance tailored to the cabinet's characteristics.
