Q-Sys AC-S4T-BK

The Q-SYS AC-S4T is a compact and flexible two-way surface-mount speaker, designed for installations where clear speech reproduction and even coverage are essential. With its wide dispersion and robust construction, it is an excellent choice for everything from conference rooms to public spaces.

Clear and balanced sound
The AC-S4T combines a 4” low-frequency driver with a 1” aluminum tweeter to deliver clear and natural sound across the entire frequency range. It is optimized for both speech and background music with high speech intelligibility.

Wide coverage for efficient installation
With a 130° conical dispersion, the AC-S4T provides even sound distribution over larger areas, reducing the need for multiple speakers in small and medium-sized installations.

Enhanced bass response
The ported design provides extended low-frequency reproduction down to 70 Hz, delivering a fuller sound than its size suggests.

Flexible system integration
The built-in 70/100V transformer (up to 16 W) and 8-ohm bypass make the speaker compatible with both distributed and low-impedance systems. Support for Q-SYS Intrinsic Correction™ optimizes sound performance and simplifies installation.

Easy installation
The included yoke bracket enables quick and secure mounting in both wall and ceiling applications. Euroblock connectors with loop-through make cabling simple and efficient.

Discreet and durable design
The UV-treated ABS cabinet and powder-coated grille ensure a long service life. The speaker is available in both black and white to blend into various environments.
