QSC AC-C8T 8-inch 2-way, 100? conical. The white Acoustic Coverage Series QSC AC-C8T?is a pair of transformer-equipped 8″ ceiling loudspeakers voiced to deliver enhanced clarity in the vocal range, making them suitable for 70/100V or 8-ohm operation in a variety of paging, A/V conferencing, and background music applications.

Outfitted with an 8″ polypropylene woofer and a coaxially mounted 0.86″ silk dome tweeter in a blind mount assembly with a ported baffle, the AC-C8T offers broad 100? conical coverage while providing a frequency range of 52 Hz to 20 kHz (-10 dB). The speaker is capable of handling 80W RMS and producing a peak maximum SPL of 114 dB.

The AC-C8T utilizes a 4-pole Euroblock connector under a swivel plate for easy input and loop-thru wiring. Mounting hardware is included for simplified in-ceiling installation.

  • Low-saturation, low-loss 70/100V transformer with 8-ohm bypass
  • Rotary tap-selector switch accessible under the painted steel grille
  • 4-pole Euroblock connector with loop-thru wiring located under a quick-access swivel plate for easy system wiring
