QSC E115-BK – 15-Inch 2-Way Passive Loudspeaker (Black)

Product Overview

The QSC E115-BK is a 15-inch two-way passive loudspeaker from QSC's E Series, providing professional-grade full-range coverage in a portable and installable cabinet. The 15-inch woofer and horn-loaded compression driver deliver high SPL with wide frequency response for live reinforcement, install main-speaker, and supplemental PA use.

It requires external power amplification and supports an optional yoke mount for installation applications.

Product Description

The E115-BK pairs a 15-inch woofer with a compression-driver horn for high-output, full-range two-way coverage suited to live sound, permanent-install main speakers, and supplemental PA. As a passive design, it is driven by an external amplifier — QSC GX and DCA Series amplifiers are well matched and, with QSC DSP-equipped amplifiers, support E Series factory tunings.

For installation, an optional E15YM-BK yoke mount allows fixed wall or structure mounting. The black cabinet is built for both portable and installed deployment.

For a 12-inch model, see the QSC E112; for low-frequency extension, the QSC E118SW.
