QSC AD-C6T-HC – AcousticDesign 6.5-Inch 2-Way High-Ceiling Blind-Mount Ceiling Speaker (70/100V)

Product Overview

The QSC AD-C6T-HC is a 6.5-inch, two-way high-ceiling ceiling-mount loudspeaker from the AcousticDesign Series, engineered for venues with high ceilings or reverberant acoustics such as ballrooms, airports, atriums, and lobbies. Its coaxial driver and tight 75° conical coverage project speech and music down from elevated mounting heights while maintaining intelligibility and tonal quality at listener level. With a 16Ω bypass plus 70V/100V transformer taps, the AD-C6T-HC drops into distributed commercial audio systems and pairs with Q-SYS Intrinsic Correction voicing for fast, high-performance installation.

Product Description

The AD-C6T-HC uses a 6.5-inch paper-cone woofer with a 1.4-inch compression tweeter in a coaxial arrangement, delivering higher power handling and a tighter 75° coverage pattern than standard ceiling speakers so it can cover seating areas from greater mounting heights. A 3x double-stepped, long-travel dog-ear blind-mount system secures the loudspeaker without visible hardware for a clean ceiling appearance, and multiple 70V/100V taps plus a 16Ω bypass make it suitable for both distributed and low-impedance systems. As part of the AcousticDesign Series, it shares consistent tonal characteristics with companion ceiling, pendant, and surface models, so audio stays uniform as listeners move through a venue. For lower ceilings or background-music zones, compare it with the AC-C8T, or browse the full QSC range at Creation Networks.

Frequently Asked Questions

What makes the AD-C6T-HC a “high-ceiling” loudspeaker?
It combines higher power handling with a tighter 75° conical coverage pattern than a standard ceiling speaker, so it can deliver adequate SPL and intelligibility at floor level when mounted in tall spaces such as atriums, ballrooms, and lobbies.

Can it run on both 70V/100V and 16-ohm systems?
Yes. The AD-C6T-HC offers 70V taps (7.5, 15, 30, 60 W) and 100V taps (15, 30, 60 W) for distributed systems, plus a 16Ω bypass for low-impedance operation.

What cutout size does installation require?
The AD-C6T-HC requires a Ø305 mm (Ø12 in) cutout. The optional AD-MR8 pre-install mud ring and AD-C305C collar adapter use the same 305 mm cutout.

Does it work with Q-SYS?
Yes. Q-SYS Intrinsic Correction custom voicing filters are available via Q-SYS Core processors to optimize performance, and the speaker shares AcousticDesign Series tonal characteristics for mixed installations.

What warranty and support are available?
The AD-C6T-HC is covered under QSC's warranty terms. For current warranty details and installation support, contact Creation Networks.
