A Speaker from the E Series: QSC's "Passive Pro" Approach

Designed for concert halls, clubs, and event providers, the E series features professional passive speakers engineered to deliver consistent performance in demanding environments. The E112 sits at the heart of this range with a highly appreciated 12-inch format for its versatility. When paired with DSP-compatible amplifiers or a digital mixing ecosystem, it can utilize tailored processing and settings to optimize sound output according to the application and sound system configuration.

Backed by several decades of experience in audio solutions for live events and installations, QSC emphasizes three pillars: high performance, reliability, and build quality. The E112 embodies these fundamentals in a robust passive speaker, ready for daily professional use.

Intended Uses: Front of House, Fill, Monitor, Mobile Performance

The QSC E112 targets musicians, sound technicians, DJs, and rental companies looking for a 2-way passive speaker capable of delivering powerful and clean sound reinforcement. Its 12-inch driver makes it an excellent choice as a front of house speaker for small to medium events, as a system fill to complement existing coverage, or as a stage monitor depending on placement. On a stand, it is well suited for mobile performances where headroom and clear vocal intelligibility are expected.
