QSC AC-S4T AcousticCoverage Surface Mount Loudspeaker

The AC-S4T pairs a 100 mm polypropylene woofer with a 25 mm aluminum dome tweeter in a surface-mount enclosure for wide area paging, background music, and distance conferencing reinforcement in healthcare facilities, concourses, and transportation terminals. 130 degrees of conical coverage keeps fixture counts down when speakers are mounted close together.

A 16-watt low-saturation 70/100V transformer with an 8 ohm bypass runs off a rear-mounted rotary selector, and the 4-pole Euroblock connector accepts four 18 AWG pairs for loop-through wiring. The UV-treated ABS enclosure mounts on the included yoke via brass inserts and thumb bolts, with a rotatable logo badge for either horizontal or vertical installs.
