QSC AP-5122 AcousticPerformance Loudspeaker
The AP-5122 pairs a 12 inch woofer with a high power-capacity 3 inch diaphragm compression driver for installs that need higher SPL output in a more compact box than the AP-5152. DMT (Directivity Matched Transition) matches LF and HF coverage at the crossover point, and the axisymmetric waveguide keeps that 90 degree pattern consistent both on and off axis.
The cabinet is 15-ply Baltic birch with 15 M10 threaded inserts for eyebolt suspension plus mounting points for the optional AP-YM12 yoke bracket, and it runs passive or bi-amplified through covered barrier strip terminals and an NL4 Speakon connector. It ships in black or white with an unadorned steel grille.
