The QSC E112 is a high-performance, passive two-way loudspeaker engineered for demanding professional sound reinforcement applications. It is designed to deliver exceptional clarity, high output, and wide dispersion for live music, portable PA systems, and fixed installations. The speaker features a 12-inch low-frequency driver paired with a 1.75-inch titanium diaphragm high-frequency compression driver, which is coupled to a proprietary waveguide for precise pattern control. With a peak power handling of 1600 watts, the E112 is capable of producing significant sound pressure levels while maintaining low distortion, making it suitable for use as a main speaker for small to medium-sized venues or as a powerful stage monitor.

The cabinet is constructed from durable, void-free Baltic birch plywood with an impact-resistant polyurea finish, making it roadworthy for touring while also providing a textured, non-slip surface. Its trapezoidal shape allows for versatile arraying as both a vertical and horizontal array element, and integrated M20 rigging points with built-in angles facilitate quick and safe flyware integration. The speaker's passive crossover network is optimized for smooth response and driver protection, and the rear panel features dual NL4 Speakon connectors for daisy-chaining multiple cabinets, along with a 1/4-inch jack input for flexibility.

Designed for use with external amplifiers from the QSC PLD or similar professional series, the E112 is a cornerstone of many portable and installed systems. Its combination of robust construction, precise acoustics, and high power handling provides a reliable and sonically transparent platform for engineers and musicians. The speaker excels in delivering articulate vocals and detailed instrumentation across its frequency range, cementing its role as a versatile and trusted loudspeaker in the professional audio market.
