QSC AD-S12 AcousticDesign 12 inch Surface-Mount Loudspeaker
The AD-S12 is the largest full-range box in the AcousticDesign surface-mount line, matching a 12 inch weather-resistant woofer to a 1.4 inch voice coil compression driver on a 75 degree conical DMT waveguide. The tighter pattern and 126 dB peak capability are what separate it from the smaller AD-S models: it is meant to throw across a gym, a large worship room or a bar patio rather than fill a corridor.
This is the low-impedance model, rated 300 watts into 8 ohms with no transformer, so it pairs with a conventional amplifier rather than a 70 V line. It is IP-54 rated, ships with the X-Mount system and an input panel cover, and accepts the optional YMS12 yoke mount or M10 eyebolt kit for flown installations.
