JBL AC18/26 Compact 2-Way Loudspeaker with 1 x 8 LF

JBL AC18/26 Compact 2-Way Loudspeaker

The AC18/26 delivers punchy, articulate output that cuts through live environments without overwhelming the mix, making it a dependable choice for intimate venues and mid-sized rooms where clarity matters. Its compact footprint and 12.8 kg weight strike a practical balance between portability and acoustic capability, allowing quick setup and repositioning without sacrificing performance. The passive design pairs a tight, focused 8-inch low end with crisp, detailed highs—ideal for vocals, instruments, or supplemental PA coverage.

Audio Performance & Coverage

The 1 x 8" LF driver combined with a 1" HF compression driver and 120° x 60° field rotatable PT Waveguide delivers focused, directional sound with a Directivity Index of 8 dB across the midrange and treble. Frequency response spans 63 Hz – 19 kHz (±3 dB), with extended reach down to 52 Hz at -10 dB, ensuring both presence and low-end definition across a wide range of program material.

Connectivity & Build Quality

Dual Neutrik NL4 connectors plus screw terminal backing provide flexible wiring options for permanent or temporary installations. Suspension points at six M8 mounting locations—one top, three bottom, two rear—enable secure rigging or stand mounting, while the black DuraFlex™ finish resists wear in touring and rental environments.
