JBL ASB7128-WH High Power Dual 18-inch Subwoofer – Black

JBL ASB7128 Ultra Long Excursion High Power Dual 18-inch Subwoofer (White Finish)

The JBL ASB7128 Ultra Long Excursion High Power Dual 18-inch Subwoofer in white is engineered for demanding professional audio environments that require maximum low-frequency impact with exceptional clarity and reliability. This high-output subwoofer system houses two JBL 2269H 460 mm (18 in) Differential Drive® woofers, each featuring a 100 mm (4 in) dual voice coil, dual magnetic gap design, and lightweight neodymium magnet structure. This advanced motor assembly delivers extremely high efficiency, reduced power compression, and outstanding transient response even at sustained high sound pressure levels.

JBL’s proprietary Vented Gap Cooling™ technology ensures superior thermal management by efficiently dissipating heat from the voice coils, allowing the subwoofer to maintain consistent performance during extended operation. The ultra-rugged composite cones support extreme cone travel, enabling a peak-to-peak excursion capability of up to 89 mm (3.5 in) for deep, accurate, and impactful bass reproduction.

The front-loaded, vented enclosure design incorporates a large port area to deliver high acoustic output with minimal distortion. The cabinet is constructed from 16 mm (5/8 in) exterior-grade 11-ply birch plywood, providing excellent structural rigidity and long-term durability. A white DuraFlex™ finish enhances visual integration in modern installations, while the powder-coated 14-gauge perforated steel grille offers robust driver protection.

Sixteen M10 threaded suspension points allow flexible rigging for ground-stacked or suspended configurations. The ASB7128 supports parallel or discrete input modes and integrates seamlessly with JBL AE Series full-range systems through FIR tuning for precise phase alignment. Origin of country mexico.
