The QSC AcousticCoverage™ Series AC-C8T is a ceiling-mounted 8-inch twoway 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. The high quality 8-inch polypropylene cone transducer with butyl rubber surround and the sensitivity matched coaxially mounted .86-inch silk dome tweeter offers pristine clarity through the critical vocal range for increased speech intelligibility. With 100 degrees of conical coverage, the AC-C8T reduces the number of loudspeakers required for even coverage in low ceiling applications. The easy-to-install blind mount assembly features a ported baffle which optimally tunes the plated steel backcan for added musicality, creating low frequency extension down to 52 Hz. To maintain this frequency response, the AC-C8T utilizes a 60-watt low-saturation and low-loss 70/100V transformer with varying selectable taps, including an 8Ω bypass. The rotary tap selector switch is accessible under the painted steel grille.
