QSC AC-S4T-WH 4" Two-Way Surface Mount Loudspeaker, White

Designed for clear voice paging, background music and monitoring in commercial, healthcare and transportation environments, the QSC AC-S4T-WH 4" two-way surface mount loudspeaker delivers reliable speech intelligibility where it matters most. The AcousticCoverage loudspeaker combines a 4" polypropylene woofer and 1" aluminum-dome tweeter with a tuned ported baffle to produce natural-sounding vocals and extended bass down to 70 Hz, helping security and surveillance teams hear announcements with confidence. With 130° conical dispersion and 85 dB sensitivity, the AC-S4T reduces the number of cabinets required for even coverage, lowering material and labor costs. Installers benefit from a 16-watt low-saturation 70/100V transformer with selectable taps and an 8 Ω bypass, plus a 4-pole Euroblock for loop-thru wiring and included yoke mount for quick surface mounting. The UV-treated, paintable ABS enclosure is built for indoor commercial spaces and integrates easily with Q-Sys networked audio platforms for advanced voicing and monitoring. Backed by QSC quality and a 3-year limited warranty, the AC-S4T-WH is an efficient choice for paging, BGM, and surveillance audio. Specify it for your next office, hospital, or transit PA deployment.
