JBL ASB7128 Dual 18" Ultra High-Power Passive Subwoofer with Dual 2269H Differential Drive® Vented Gap™ Woofers, Multiplywood Enclosure, Black Finish (ASB7128)

The JBL ASB7128 is an ultra high-power dual 18-inch passive subwoofer engineered for professional sound reinforcement applications that demand extreme low-frequency output, exceptional efficiency, and uncompromising reliability. Equipped with two JBL 2269H Differential Drive® Vented Gap™ woofers, the ASB7128 delivers powerful, deep bass reproduction with outstanding transient response and minimal distortion, even at very high sound pressure levels.

At the heart of the ASB7128 are dual 2269H low-frequency transducers featuring JBL’s advanced Differential Drive® technology. Utilizing dual voice coils and dual magnetic gaps, the design reduces overall weight while increasing power handling, efficiency, and thermal performance. JBL’s Vented Gap™ cooling technology further enhances heat dissipation, allowing the system to maintain consistent performance during extended high-output operation.

Constructed from rugged multiplywood and finished in durable black coating, the ASB7128 is designed to withstand the rigors of touring productions and permanent installations alike. It is ideal for concert venues, theaters, arenas, stadiums, houses of worship, performing arts centers, convention facilities, nightclubs, and large-scale professional audio systems requiring extreme low-frequency impact.
