QSC AC-S4T-WH Surface Mount Loudspeaker
The QSC AcousticCoverage™ Series AC-S4T is a surface mounted 4” two-way loudspeaker with 70/100V transformer, suitable for a wide variety of audio/video conferencing reinforcement, voice paging and background music applications.

AcousticCoverage™ Series is designed to offer integrators a cost effective solution for applications where voice reinforced coverage is of primary concern, while providing improved musicality often not seen in typical BGM class products.

A high quality 100 mm [4 in] polypropylene cone transducer with butyl rubber surround and a 25 mm [1 in] aluminium dome tweeter offers pristine clarity through the critical vocal range for increased speech intelligibility. With 130 degrees of conical coverage, the AC-S4T 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 70 Hz. To maintain this frequency response, the AC-S4T utilizes a 16-watt low-saturation and low-loss 70/100V transformer with varying selectable taps, including an 8O bypass.

To further enhance performance and speed of install with optimum result, advanced voicing via QSC Intrinsic Correction™ techniques are obtainable using the Q-SYS™ Platform and in CXD Series amplifiers for a complete QSC systems solution.

Installers will appreciate the 4-pole Euroblock connector for loop thru wiring, located on the rear of the enclosure. Eliminating the termination hassles of star topology wiring designs, the generous Euroblock of the AC-S4T can accept four 18AWG pairs.

The AC-S4T 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.
