JBL AC266 Two-Way Full-Range Loudspeaker with 1 x 12 LF

The AC266 delivers punchy, articulate sound that cuts through any live performance setting. The 12-inch woofer provides a solid, present low-end that feels responsive and controlled, while the two-way configuration balances rich midrange clarity with extended highs, letting every detail of your performance shine through without harshness. This is the kind of speaker that makes you trust what you hear—honest, immediate, and inspiring.

Audio Performance & Coverage

With a system sensitivity of 97 dB at 1W/1m and maximum SPL capabilities of 121 dB (127 dB peak), the AC266 projects articulate, full-range sound across venues of varying sizes. The 60° × 60° coverage pattern ensures consistent output throughout the listening area, while the frequency response of 80 Hz–18 kHz (±3 dB) and extended range down to 63 Hz (–10 dB) capture everything from tight bass definition to crystalline vocal presence and instrumental detail.

Design & Connectivity

The AC266 combines robust construction with flexible mounting and connection options. Its 15mm enclosure with black textured finish withstands the demands of touring and permanent installation, while dual Neutrik NL4 connectors plus screw terminals accommodate various wiring configurations. Integrated M10 threaded suspension points and four rear-panel threaded inserts support MultiMount® systems and other rigging hardware for quick, secure deployment.
