JBL ASB7118 Ultra Long Excursion High Power Single 18 Subwoofer

JBL ASB7118 Ultra Long Excursion High Power Single 18 Subwoofer

The ASB7118 delivers earth-moving low-end impact with a 3.5-inch peak-to-peak excursion that transforms any performance space into an immersive sonic environment. Built on a 2269H 18-inch dual coil neodymium driver, this subwoofer produces thunderous bass with clarity and control, cutting through the mix rather than muddying it. The rigid birch plywood construction and professional-grade connectivity make it equally at home anchoring live sound reinforcement, studio monitoring, or installed venue systems.

Power & Output Capability

The ASB7118 handles 2000 W continuous (8000 W peak) and sustains 1200 W long-term (4800 W peak) over extended periods, 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 get authoritative bass response from moderate amplifier levels without compromise.

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 rigging or ground stacking in demanding installations. IP-x3 environmental rating and Mil-Std 810 compliance ensure durability in variable conditions, while Neutrik Speakon and barrier strip terminals accept professional-grade wiring up to 10 AWG.
