JBL AC266 Two-Way Full-Range Loudspeaker with 1 x 12 LF
Description
JBL AC266 Two-Way Full-Range Loudspeaker with 1 x 12 LF
The AC266 delivers punchy, articulate sound built for critical listening and recording applications. The 12-inch woofer provides a solid, present low-end that captures bass definition and tightness, while the two-way configuration balances rich midrange clarity with extended highs, letting every vocal, instrument, and mix element translate accurately without coloration. This is the kind of speaker that makes you trust your mix decisions—honest, immediate, and revealing.
Monitoring & Reference Accuracy
With a system sensitivity of 97 dB at 1W/1m and maximum SPL capabilities of 121 dB (127 dB peak), the AC266 delivers articulate, full-range reproduction suitable for control-room monitoring and project-studio environments. The 60° × 60° coverage pattern ensures consistent response across the mixing position, while the frequency response of 80 Hz–18 kHz (±3 dB) and extended range down to 63 Hz (–10 dB) capture everything from low-end punch and definition to clear vocal presence and high-frequency detail.
Build & Studio Integration
The AC266 combines durable construction with flexible mounting and connection options ideal for studio setups. Its 15mm enclosure with black textured finish provides rugged reliability, while dual Neutrik NL4 connectors plus screw terminals accommodate various wiring configurations and system architectures. Integrated M10 threaded suspension points and four rear-panel threaded inserts support MultiMount® systems and custom studio rigging for accurate speaker placement and decoupling.

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.
