QSC E110-BK Passive 10-Inch Loudspeaker

The QSC E110 is a 2-way passive loudspeaker designed around a 10-inch die-cast woofer with a 2.5-inch voice coil — hardware proportions that signal this cabinet's intent: high thermal capacity, reliable power handling, and a midrange that can take the sustained energy of live music without compressing into mush. QSC's DMT engineering directly addresses one of the most audible problems in live PA deployment: the way cabinet sound changes as you move off-axis. At 85-degree horizontal coverage, the E110 maintains its tonal character across a wide listening area, which means the mix engineer's work reads consistently whether you're at FOH or standing at the edge of the coverage zone. The foam-lined steel grill is a design detail that earns its keep — the audible HF artifacts from bare grills are a real-world issue, and the foam treatment produces a cleaner, less colored top end on sources with significant high-frequency content.

The E110's passive topology makes it the right choice for engineers who already have amplification infrastructure or prefer the control flexibility of separating power and driver stages. It excels in small to medium venue main PA applications and holds its own as a stage monitor for vocal-centric mixes, where the 10-inch driver's midrange clarity shines. In low-end-heavy applications — electronic music, kick-forward live rock — the E110 is most effective paired with dedicated subwoofer support. The tour-grade construction is legitimate: this is a cabinet built for repeated use, not occasional deployment. For production companies, rental houses, or fixed installs requiring reliable, consistent coverage from a passively driven enclosure, the E110 represents QSC's engineering standards at a working professional price.
