QSC AP-4122M 12" High Power 2-Way Coaxial Installation Loudspeaker, 90° Conical DMT, Black

Engineered for permanent commercial installations, the QSC AP-4122M 12" coaxial installation loudspeaker delivers reliable, intelligible sound where it matters most. As a QSC pro speaker with Directivity Matched Transition (DMT), it produces consistent coverage across the listening plane—ideal for paging, security monitoring, and surveillance audio in airports, campuses and stadiums. The 12" coaxial driver and 3" (1.75" on AP-4122M) compression driver combine with 325W RMS power to reproduce a wide 55 Hz–20 kHz frequency range with low distortion and 96 dB sensitivity. Built from durable 15-ply Baltic birch and a powder-coated steel grille, the AP-4122M resists the rigors of permanent installs and weather-exposed spaces. Installers benefit from multiple mounting options (yoke, M10 fittings, pole cup) and NL4 Speakon connectivity for fast, secure integration into AV, security and monitoring systems. Choose the AP-4122M when you need dependable high-output performance for professional audio, surveillance paging, or distributed sound.
