JBL ASB7128-WH – Dual 18-Inch Ultra Long Excursion High-Power Subwoofer (White)

Product Overview

The JBL ASB7128-WH is a high-power, lightweight front-loaded vented subwoofer enclosure housing two JBL 2269H Ultra Long Excursion 18-inch Differential Drive woofers, finished in white for architectural installation environments. Designed for ground-stacked or suspended applications in stand-alone arrays or in combination with other JBL AE Series loudspeakers, the ASB7128 delivers 4,000 watts continuous pink noise power handling and 16,000 watts peak — providing high-output, low-distortion low-frequency reinforcement for large auditoriums, houses of worship, arenas, and performing arts venues. FIR tuning matches the phase profile to JBL AE Series full-range models, ensuring coherent system integration in commercial AV installations requiring deep, controlled bass extension.

Product Description

The ASB7128 houses two of JBL's exclusive 2269H Ultra Long Excursion 18-inch woofers, featuring neodymium magnets, dual voice coils, dual gaps, JBL's Vented Gap Cooling, and ultra-robust composite cones — capable of 89 mm (3.5 inches) of peak-to-peak maximum excursion for extreme low-frequency output with extended driver life. The front-loaded vented enclosure design provides a large vent area for high output with low distortion, suited to demanding large-venue applications. A parallel/discrete switchable input mode gives system designers flexibility in wiring configuration, and FIR (Finite Impulse Response) tuning matches the subwoofer's phase profile to JBL AE Series full-range loudspeakers — ensuring phase-coherent integration when the ASB7128 is deployed alongside other AE Series components. The white finish supports installation in architecturally sensitive environments where black enclosures are visually unsuitable. The ASB7128-WH is appropriate for ground-stacked or flown deployment in stand-alone subwoofer arrays or as the low-frequency foundation of a complete JBL AE Series system.

Frequently Asked Questions

Does the ASB7128-WH require external amplification?

Yes. The ASB7128 is a passive subwoofer requiring external amplification and DSP processing. JBL recommends pairing it with the appropriate amplifier and applying the supplied FIR tuning for optimal phase-coherent integration with AE Series full-range loudspeakers. Contact Creation Networks for amplifier recommendations.

What does FIR phase matching provide?

FIR (Finite Impulse Response) tuning matches the ASB7128's phase profile to JBL AE Series full-range models, ensuring coherent acoustic integration when the subwoofer is deployed in a complete AE Series system. This results in tight, accurate low-frequency transition between the subwoofer and full-range loudspeakers.

Can the ASB7128-WH be flown?

Yes. The ASB7128 supports both ground-stacked and suspended (flown) deployment. All rigging should be performed by qualified personnel following JBL's load and safety guidelines.
