QSC AcousticDesign Series 5.25" 2-Way Surface-Mount Loudspeaker AD-S5T-BK, Black
Clear sound, anywhere you mount it.
The QSC AD-S5T-BK is a 5.25" 2-way surface-mount loudspeaker for 70/100V systems. It delivers even coverage for background and foreground sound in commercial spaces.

Uneven sound makes a room feel unfinished.
Loud spots near one speaker and thin sound farther away make music and announcements hard to follow. Even coverage and flexible mounting help fix that.
Built for commercial installs
Coverage, mounting and weather resistance are covered in one compact black cabinet.
Smooth, uniform coverage
DMT (Directivity Matched Transition) ensures smooth, uniform frequency response over the coverage area.

IEC60529 rating
Meets IEC60529 IP-54 for dust and splash resistance.
X-Mount angle flexibility
The X-Mount system lets the loudspeaker be installed and deployed at a variety of angles without slipping over time.
70 / 100V ready
Low saturation and low loss 70 / 100V transformers come with an 8 ohms bypass.
Weather-resistant build
A sealed input panel cover and powder coated aluminum grilles add weather resistance to the lightweight ABS enclosure.
