QSC AC-C8T AcousticCoverage Ceiling Loudspeaker
The AC-C8T is the largest ceiling speaker in QSC's AcousticCoverage line, pairing an 8 inch polypropylene woofer with a coaxially mounted .86 inch silk dome tweeter for the extended low frequency and highest SPL in the family. 100 degrees of conical coverage still keeps speaker counts reasonable while adding the headroom larger rooms and higher ceilings need.
A 60-watt low-saturation 70/100V transformer with an 8 ohm bypass sits under the painted steel grille on a rotary selector, and the 4-pole Euroblock connector accepts four 18 AWG pairs for loop-through wiring. Rails and a C-ring ship with each pair-packed set for tile installs, and the white ABS baffle and plated steel back can are UL1480/UL2043 listed for air-handling spaces.
