About QSC AC-C4T


The QSC AcousticCoverage AC-C4T 4" Ceiling-Mount White Loudspeaker (Pair) is suitable for a wide variety of voice paging and background music sound reinforcement applications. AcousticCoverage AC-C4T 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 4" polypropylene cone transducer with butyl rubber surround offers pristine clarity through the critical vocal range for increased speech intelligibility. With 140 degrees of conical coverage, the AC-C4T 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 galvanized steel backcan for added musicality, creating low frequency extension down to 70 Hz. To maintain this frequency response, the AC-C4T utilizes a 16-watt low-saturation and low-loss 70/100V transformer with varying selectable taps, including an 8 Ohms bypass.

To further enhance performance and speed of install with optimum result, advanced voicing via QSC Intrinsic Correction techniques are obtainable using Q-Sys networked audio processing platforms, including CXD amplifiers for a complete QSC systems solution. Installers will appreciate the 4-pole Euroblock connector for loop thru wiring, located under a quick access swivel plate. Eliminating the termination hassles of star topology wiring designs, the generous Euroblock of the AC-C4T can accept four 18AWG pairs. A safety tether tab is affixed to the adjustable conduit clasp plate for seismic sensitive installations. C-ring and tile rails are included with each pair packed assembly, complete with joining screws and cut-out template.

The AC-C4T baffle and grill are QSC standard white (RAL 9010) to match complimenting QSC product families and includes UV inhibitors to prevent discoloration over time. The AC-C4T may also be painted to match any decor.
