Product Overview

Overview

The QSC AC-C6T is a 6.5-inch two-way ceiling loudspeaker with a 110 degree conical coverage pattern. A coaxial silk-dome tweeter on a 6.5-inch cone gives clearer speech and fuller music than a single full-range driver, which suits a standard office or meeting-room ceiling. It reaches 65 Hz to 20 kHz, carries 30 W taps for 70 V and 100 V lines, and keeps the same plenum-safe listing as the rest of the AC-C range.
