QSC ISIS I282H Surface Mount Weather Resistant Speaker
The QSC I-282H is a dual 8-inch, 2-way, full-range loudspeaker with contemporary styling that easily integrates into multiple environments. Pole mounted, truss mounted, or used as a floor monitor/stage fill, these injection molded speakers are an excellent choice for musicians, mobile entertainers, and anyone else needing a high-quality, lightweight SR package that sounds superb, is visually unobtrusive, and with its built-in handles, is easy to transport.

The HF driver is coupled with QSC's unique Advanced Directivity™ Rotatable Waveguide - enabling the loudspeaker to deliver accurately focused sound, regardless of its orientation.

For truss mounting, the yoke accepts most industry standard truss clamps.
