JBL Professional AC18-26-WH - 8" 2-Way Passive Loudspeaker (White) with 120° × 60° Rotatable PT™ Driver

The JBL Professional AC18-26-WH (official designation AC18/26-WH ) is an installation loudspeaker from the AE Compact family that combines high output, fidelity and a discreet form factor. It integrates a 205 mm JBL 228H woofer with SFG ™ geometry (64 mm voice coil) and a 25 mm exit 2408H-1 compression driver , coupled to a 120° × 60° rotatable PT ™ waveguide to ensure uniform coverage in vertical or horizontal mounting. With a sensitivity of 92 dB (1 W/1 m) , a max SPL of 116 dB and a power rating of 250/500/1000 W (continuous/program/peak, IEC), the AC18-26-WH delivers intelligibility and punch in theaters, houses of worship, hospitality or retail without compromising aesthetics. The DuraFlex™ finished plywood enclosure with a steel grille incorporates fabric behind the grille on white units for seamless visual integration. Professional connectivity includes two parallel Speakon® NL4s and a covered CE terminal block ; multiple M8/M6 mounting points simplify installation with U-brackets and third-party hardware. Official Crown amplifier presets and EASE GLL/CLF and Revit/BIM files are available for design and simulation.

Product benefits

• Aesthetics in light interiors: The white version (-WH) with fabric behind the grille blends discreetly into walls and ceilings.
• Homogeneous coverage with less overlap: The 120° × 60° rotating pattern facilitates consistent designs and improves intelligibility.
• Solid output in a compact form factor: The 8" SFG™ and compression driver deliver punch and definition in a small footprint enclosure.
• Quick and secure installation: Multiple M8/M6 points, dual connectors and dedicated U-bracket simplify mounting on a wall, column or under a balcony.
• Professional workflow: Presets and simulation files (GLL/CLF/BIM) streamline design and commissioning.

Use cases

• Theaters, auditoriums and performing arts halls.
• Places of worship and educational centers.
• Hospitality, retail and corporate spaces.
• Reinforcement under balconies, column or wall mounts, and spot coverage areas.

Frequently Asked Questions

• What does “26” mean in AC18/26? It indicates the nominal 120° × 60° coverage of the PT™ (rotating) waveguide.
• Can it be installed outdoors? The standard version is IPx3 compliant; for direct exposure or harsh climates, use WRC/WRX .
• Does it include a U-bracket? No. The MTU-18 is purchased separately.
• What amplification is appropriate? A power amp delivering 500 to 1000 W at 8 Ω per channel provides headroom and dynamic control; use the recommended Crown presets .

Compatibility and accessories

• Dedicated bracket: MTU-18 (U-bracket).
• Compatible hardware: OmniMount® 30.0; MultiMount® MM-022-BT / MM-024-BT / MM-020-CM ​​; Ultimate Support™ foot BMB-200K or K&M 195/8 ; K&M wall 24470/24480 .
• Software and files: EASE GLL , CLF , and Revit/BIM ; preset libraries for Crown I-Tech HD, DCi, and CDi.
