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 & Reliability
The AC266 combines robust construction with flexible mounting and connection options built for the road. 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.

Frequently Asked Questions
Is the AC266 suitable for studio recording or mixing?
No. The AC266 is purpose-built for live performance and gigging environments, not studio monitoring or mixing. For studio work, use a dedicated studio monitor designed for flat, accurate response in a treated room.
What amplifier power do I need to run the AC266?
The AC266 handles 250 W continuous power (350 W AES), 500 W program, and up to 1000 W peak. A powered amp or head rated between 350–500 W will deliver solid performance; higher-wattage amps offer headroom for peaks and larger venues.
How does the AC266 compare to the QSC K12.2 or Electro-Voice ZLX-15?
The AC266 is a direct competitor in the touring two-way, 12-inch category, offering similar sensitivity (97 dB), high maximum SPL (121 dB), and road-rated construction. All three deliver punchy midrange and extended highs; your choice depends on tonal preference, available rigging hardware, and your existing rig.
Does the AC266 include rigging hardware, cables, or a cover?
The AC266 includes dual Neutrik NL4 connectors plus screw terminals, and M10 suspension points with MultiMount threaded inserts for rigging. Cables, amplifier, and protective cover are not included and must be sourced separately.
What is the coverage pattern, and will it work in my venue?
The AC266 offers a 60° × 60° coverage pattern (horizontal and vertical) with a 97 dB sensitivity and 121 dB maximum SPL, projecting consistent output across venues ranging from small clubs to mid-sized theaters. Exact performance depends on room size, distance from the speaker, and ambient noise.
