The QSC AD-S.SAT is part of the AcousticDesign Series SUB/SAT loudspeaker line which are ideally suited for background music applications that require refined depth and clarity even at lower volume settings. The AcousticDesign Series offers integrators a premium quality installed sound solution where performance, consistent coverage, and aesthetics are paramount. Specifically designed to maintain a consistent tonal characteristic across the entire family in ceiling, surface, and pendant enclosures, the AcousticDesign Series allows integrators seamless transitions within blended installations. The AcousticDesign Series SUB/SAT loudspeakers have been specifically designed to be mix-and-match capable. Any combination of satellites may be paired with any subwoofer in the SUB/SAT line. The AD-S.SAT features a high quality 2.75-inch weather treated paper cone woofer with an inverted aluminum dust cap for extended high frequency presence within a sealed enclosure. These loudspeakers are rated at 16 O, and up to four satellites may be connected to any AcousticDesign Series SUB/SAT subwoofer's high-pass filtered outputs. Satellites also may be used as stand-alone loudspeakers using an external high-pass filter. The input is located on the rear of the loudspeaker and uses a locking 2-pole Euroblock style connectors capable of 12AWG (2 mm) wire thickness. To retain their stylish aesthetics, the rugged ABS baffle is further protected by using UV inhibitors that prevent discoloration. The grille features a stick-on logo that can be removed blemish-free for installations where branding is not permitted. Installers will appreciate X-Mount Mini hardware that ships with the satellites. This mounting solution allows for repeatable angles without drift or sag over time. The mount may be rotated on all four 90° axes for versatile wall or ceiling mounting options.
