Surface-Mounted Speakers

The QSC AcousticDesign AD-S282H 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. Available in black or white, these weather resistant enclosures can be painted to match any specific decor.

The AD-S282H is a 2-way system housed in a ported enclosure made from injection molded, high- impact polystyrene. This enclosure incorporates two 8 inch weather resistant, LF transducers with heavy- duty double roll cloth surrounds. These high output versions employ a 1 inch 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.
