What QSC Audio does

QSC Audio designs and manufactures professional powered loudspeakers, subwoofers, line arrays, column systems, and supporting software for live sound, event production, and installed AV. Founded in 1968 and headquartered in Costa Mesa, California, the company sells through a global authorized dealer network across North America, Europe, and Asia-Pacific, with localized India storefront support. Its portfolio is tiered — CP Series (compact value), K.2 Series (premium portable powered), L Class (networked intelligent line array with LA108, LA112, LS118, LS218), and K Column (KC12) — and is differentiated by proprietary acoustic and DSP technologies including the LEAF™ waveguide, Acoustic Linear Phase design, AWARE™ automatic array recognition, RapidDeploy™ rigging, SysNav™ system design software, and a new Loudspeaker Control mobile app.

Underlying technology centers on Class D amplification (up to 5,000W peak in LS218), onboard DSP with recallable scenes, Dante® audio-over-IP networking, and integration with the Q-SYS ecosystem for unified AV control. QSC targets musicians, DJs, presenters, rental and AV production companies, system integrators, houses of worship, and public-address applications, with products organized for portable, installed, and touring use cases. Revenue is generated almost entirely through hardware sales via dealers, supplemented by spare parts (parts.qsc.com) and free training/education programs that double as demand generation.

Since 2025, QSC Audio has operated as the audio core within Acuity Inc.'s Acuity Intelligent Spaces business segment, giving it access to Acuity's lighting and building-management channels for integrated smart-building propositions. The company continues to ship new products — including the January 2026 launches of the CB10 battery-powered loudspeaker, LS218 dual 18-inch subwoofer, and Loudspeaker Control app — and maintains a 6-year warranty on registered products.
