The Q-SYS AcousticDesign two-way ceiling speaker series with 70/100V transformer is engineered for integrators deploying distributed audio in commercial, hospitality, corporate, and institutional environments. Available in 4.5" and 6.5" driver configurations, the series covers a range of coverage patterns and power requirements, allowing installers to match speaker selection to room size and system design without changing the visual or operational footprint. Each model ships with a C-ring, tile rails, and installation hardware, supporting blind mount installation without access to the ceiling plenum.

Tonal consistency across the AcousticDesign family makes these speakers a reliable choice in multi-zone systems where surface-mount and ceiling-mount speakers must perform cohesively. The Directivity Matched Transition waveguide maintains smooth, uniform frequency response across the rated coverage angle, reducing hotspots and dead zones in reverberant spaces. Low-saturation, low-loss 70/100V transformers with 16-ohm bypass give engineers flexibility to run constant-voltage or low-impedance configurations from the same enclosure. Advanced Intrinsic Correction voicings are available through Q-SYS for system-level optimization without additional DSP hardware.

The zero-bezel profile and snap-fit magnetic grille satisfy modern architectural specifications where speaker visibility must be minimized. The ABS baffle on a powder-coated steel back can and IP-34 ingress protection rating support installation in plenum and light-duty environments. UL1480 and UL2043 certification, along with NFPA 90 and NFPA 70 compliance, qualifies the series for use in air-handling spaces, broadening the range of install scenarios where these speakers can be deployed.
