JBL ASB7118 Ultra Long Excursion High Power Single 18 Subwoofer

The ASB7118 anchors your low-end foundation with a 3.5-inch peak-to-peak excursion that captures and reproduces sub-bass with precision and control. Built on a 2269H 18-inch dual coil neodymium driver, this subwoofer delivers articulate bass that sits solidly in the mix without overwhelming or clouding other frequencies. The rigid birch plywood construction and professional-grade connectivity make it ideal for studio monitoring, hybrid production setups, or installed venue systems where accurate low-frequency reproduction matters.

Power & Output Capability

The ASB7118 handles 2000 W continuous (8000 W peak) and sustains 1200 W long-term (4800 W peak) over extended sessions, delivering 129 dB-SPL continuous average and 135 dB peak output across its operating range. This power handling combined with 96 dB sensitivity means you achieve deep, controlled bass response at practical monitoring levels without driving amplification into distortion.

Design & Construction

The enclosure uses 16 mm 11-ply exterior-grade birch plywood with 16-point M10 suspension attachment points (4 each: top, bottom, and sides), enabling secure placement in fixed installations or flexible studio configurations. IP-x3 environmental rating and Mil-Std 810 compliance ensure durability across varied studio and venue conditions, while Neutrik Speakon and barrier strip terminals accept professional-grade wiring up to 10 AWG for secure signal transfer.
