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 8Ω bypass.
