Q-Sys AC-C4T

The Q-SYS AC-C4T is a compact and cost-effective ceiling speaker, designed for installations where clear speech reproduction and even coverage are key. With a 4-inch full-range driver and wide dispersion, it is ideal for conference rooms, retail stores, and public spaces.

Optimized for speech and background music
The AC-C4T uses a high-quality 4-inch full-range driver that delivers clear and distinct reproduction in the critical speech range. It is specifically designed for paging, conferencing, and background music where speech intelligibility is crucial.

Wide coverage – fewer speakers
With a 140° conical dispersion, the AC-C4T provides an even sound field over large areas, reducing the need for multiple units in installations with low ceiling heights.

Enhanced bass in a compact format
The ported baffle is optimized in conjunction with the rear enclosure to provide better low-frequency reproduction down to 70 Hz—uncommon for this size.

Simple and flexible installation
The speaker features a smart flush-mounting solution with included rails and a C-ring for suspended ceilings. Euroblock terminals with loop-through make wiring quick and efficient, even in larger systems.

Flexible system integration
With a built-in 70/100V transformer (up to 16 W) and 8-ohm bypass, the AC-C4T can be used in both distributed and low-impedance systems. Support for Q-SYS Intrinsic Correction™ ensures optimized performance and quick commissioning.

Discreet and durable design
The white (RAL 9010) cabinet and grille with UV protection ensure that the speaker retains its appearance over time and blends into most environments.
