One of the QSC AcousticCoverage™ Series’ “no back can” models, AC-C4T-nb is a full-range ceiling-mounted loudspeaker. Built to deliver optimal speech intelligibility, its weather-treated, 4.5-inch transducer features a paper cone design that delivers exceptional clarity, while its whizzer cone improves high-frequency dispersion throughout the critical vocal range.
This speaker’s wide dispersion angle enables you to get better coverage over an area using fewer speaker units—even in installations with low ceilings. The 6W low-saturation, low-loss 70/100V transformers have color-coded bare wire terminations to avoid the cost of rotary selectors.
Premium audio quality—in an install-friendly build. The AC-C4T-nb’s blind mount assembly features four dog-ears under the torsion-fit powder-coated steel grille.
