The JBL PROFESSIONAL AC266 is a two-way, full-range passive loudspeaker designed for professional sound reinforcement applications. Built around a 12-inch low-frequency driver, it delivers broad frequency coverage suited to fixed-installation environments. The AC266 is a passive design, meaning it requires an external amplifier to operate. Installation is handled by professional audio/visual technicians or low-voltage systems integrators working to local AV and electrical codes.
The AC266 is intended for permanent or semi-permanent installation in commercial and institutional settings. Typical applications include houses of worship, lecture halls, retail spaces, restaurants, and similar venues where consistent, wide-coverage speech and music reproduction is required. The full-range, two-way configuration makes it suitable for both foreground music and voice reinforcement without supplemental subwoofer support in moderate-output scenarios.
Designed as an OEM-style fixed-installation passive loudspeaker compatible with standard professional amplifier outputs; specific system pairings should be verified against the manufacturer's published specifications.
Installation should be performed by a qualified AV integrator or low-voltage technician familiar with professional sound reinforcement systems. Ensure all amplifier output connections are de-energized before wiring the loudspeaker. Follow applicable local electrical and building codes for speaker mounting hardware and cable routing. Do not exceed the loudspeaker's rated power handling as specified by the manufacturer.
