JBL Professional ASB7128-WH Dual 18" Subwoofer, White

For professional AV integrators and event producers who need authoritative low-frequency performance, the JBL Professional ASB7128-WH Dual 18" Subwoofer delivers industry-leading bass impact and reliability. This pro subwoofer combines two JBL 2269H Differential Drive® 18" woofers with neodymium motors and ultra-long excursion capability to produce tight, powerful lows down to 25 Hz—ideal for live sound, cinema, and monitoring or security rooms where accurate low-end reproduction matters.

With 2400W RMS power handling, a 4-ohm design and 99 dB sensitivity, the ASB7128-WH converts amplifier power into high SPL efficiently, reducing amplifier load while maintaining clarity. The vented, front-loaded birch enclosure and robust construction (14-gauge steel grille, multiple threaded attachment points) make it simple to deploy in flown arrays or ground stacks. Parallel and discrete wiring modes give system designers flexibility for distributed audio or redundancy in surveillance and monitoring applications.
