Description

The black AcousticCoverage Series QSC AC-S4T is a pair of transformer-equipped 4.5″ surface-mount 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 a 4″ polypropylene woofer and a 1″ aluminum dome tweeter in a UV-treated ABS enclosure with a ported baffle, the AC-S4T offers broad 130° conical coverage while providing a frequency range of 70 Hz to 20 kHz (-10 dB). The speaker is capable of handling 16W RMS and producing a peak maximum SPL of 103 dB.

The AC-S4T utilizes a 4-pole Euroblock connector on the rear panel for easy input and loop-thru wiring. A yoke bracket is included for simplified surface-mount installation.
