The QSC AcousticCoverage™ AC-S6T is a surface mounted 6.5” two-way loudspeaker with 70/100V transformer, suitable for a wide variety of voice paging and background music sound reinforcement applications.

A high quality 6.5" (165 mm) polypropylene cone transducer with butyl rubber surround and a 1" (25 mm) aluminium dome tweeter offers pristine clarity through the critical vocal range for increased speech intelligibility. With 130° of conical coverage, the AC-S6T reduces the number of loudspeakers required for even coverage in close proximity.

The UV treated high impact ABS enclosure and ported baffle assembly has been optimally tuned for added musicality, creating low frequency extension down to 60 Hz. To maintain this frequency response, the AC-S6T utilizes a 30W low-saturation and low-loss 70 / 100 V transformer with varying selectable taps, including an 8 Ω bypass.

The AC-S6T features brass inserts to accept the included yoke mount and is secured using the supplied thumb bolts. The grille is adorned with a spring loaded and rotatable logo for installation convenience in either horizontal or vertical deployments.
