QSC AD-S402T AcousticDesign 4-Driver Column Array Loudspeaker
The AD-S402T is the compact end of QSC's AcousticDesign column array line, packing four 2.75 inch weather-treated paper cone drivers into a slim 12.9 inch enclosure for rooms that need even vertical coverage without a full-size column speaker. Its narrow profile mounts flush to a wall for background and foreground paging in retail, hospitality, and small house of worship spaces.
Rated for 60 watts on a 16 ohm line, it shares the AcousticDesign family's paintable, UV-stable enclosure and ships in black or white to match adjoining AD-S surface-mount speakers on the same job.
