The QSC AcousticDesign AD-S282HT is a full-range, surface-mount loudspeaker with a sleek, contemporary styling that fits perfectly into multiple surroundings and applications including hotels, restaurants, convention facilities, and multimedia environments.  The speaker incorporates the Advanced Directivity™ rotatable waveguide. Comes in a black weather resistant enclosure.

The AD-S282HT is a 2-way system housed in a ported enclosure made from injection-molded, high-impact polystyrene. This enclosure incorporates two 8" weather-resistant, LF transducers with heavy-duty double roll cloth surrounds. These high output versions employ a 1" exit compression HF driver. The HF driver is coupled with QSC's unique Advanced Directivity rotatable waveguide - enabling the loudspeaker to deliver accurately focused sound, regardless of its mounted orientation.
