QSYS AD-C6T-HC Ceiling Speaker

Q-SYS AD-C6T-HC, a 2-way passive in-ceiling loudspeaker featuring a 6.5-inch woofer and a 1.4-inch compression tweeter, designed for professional installations with high ceilings or reverberant spaces where higher output and more controlled dispersion are required.

Its design provides a 75° coverage angle, allowing more focused sound projection compared to wider-dispersion models. This makes it suitable for high-ceiling venues, churches, auditoriums, commercial installations and other environments where better control of acoustic energy and reduced unwanted reflections are required.

The AD-C6T-HC features a 6.5-inch woofer with a 1.75-inch voice coil and ferrite magnet, along with a 1.4-inch compression tweeter with a Kapton dome. It offers a frequency response of 45Hz–20kHz, 90dB sensitivity and a rated noise power of 120W in 16Ω bypass mode. Maximum SPL reaches 110dB continuous and 116dB peak.

It supports 70V/100V distributed systems through multiple transformer taps, as well as 16Ω bypass operation. Connection is provided via a 4-pin Euroblock connector with parallel output, simplifying daisy-chain wiring in multi-loudspeaker installations.

For installation, it uses a blind-mount system with three double-stepped, long-travel dog-ear mounting points and features a snap-fit magnetic grille. It also supports Q-SYS Advanced Intrinsic Correction™ voicings for optimized performance within the Q-SYS ecosystem.
