QSC Pro audio E110

The E Series: Professional Passive Speakers at the Heart of the QSC Ecosystem

With the E Series, QSC offers a range of passive speakers aimed at live sound and installation applications, designed to meet the demands of concert halls, clubs, and service providers. The E110 is part of a family of six models built with plywood enclosures, featuring a robust finish and careful speaker protection thanks to a steel grille backed with foam. When paired with QSC GXD or PLD amplifiers, or integrated into a setup with a TouchMix digital console, the E Series can utilize DSP and factory presets to optimize performance according to usage and configuration.

Drawing on over 50 years of experience in audio technologies for live performance, cinema, and professional environments, QSC is founded on a clear philosophy: performance, reliability, and sonic consistency, delivering systems that inspire confidence both on stage and under intensive use.

What Applications Is the QSC E110 Designed For?

The QSC E110 targets musicians, sound engineers, DJs, and service providers seeking a 10-inch passive speaker capable of delivering precise sound reinforcement in various contexts: stage monitoring, front-of-house reinforcement in small to medium-sized venues, club sound reinforcement, or fixed installations requiring a discreet yet serious format. Its balance of size, output level, and coverage makes it a relevant choice when maintaining midrange definition and strong presence is desired without moving to a bulkier format.

Thanks to its 35 mm dual-angle pole mount, the E110 can be easily positioned vertically on a stand or tilted 10 degrees downward to better target the audience and reduce unwanted reflections in reverberant spaces.

Design, Sound Dispersion, and Integration: What Sets It Apart

An Efficient 2-Way Configuration for Clarity

The E110 features a 2-way design with a 10-inch woofer and a 1-inch tweeter. This architecture aims for an effective compromise between impact, clarity, and projection, particularly useful for vocals, amplified instruments, and musical content requiring good high-frequency definition.

85 Deg Conical DMT Coverage: Uniformity in the Listening Area

The nominal 85-degree conical DMT coverage is designed to maintain consistent dispersion. Practically, this helps achieve a more even listening experience within the coverage zone, with better control of directivity, facilitating speaker placement and overall system balance, especially in acoustically challenging venues.

Professional-Grade Construction

The plywood cabinet, textured black paint, and steel grille with foam protection are built to withstand repeated handling. Whether for transport, quick setup, or installations that must remain visually neat, the E110 emphasizes durability and a polished appearance.

Practical Connectivity for Live Sound and Installation

On the connection side, the E110 offers two NL4 connectors plus a terminal block, simplifying integration into passive systems (daisy-chaining, distribution, or wiring adapted to an installation). The ability to leverage presets via compatible amplifiers and/or a coherent QSC setup also saves time during setup and quickly delivers controlled results.
