JBL AC115S-WH 15" High-Power Subwoofer System (White)

Product Overview

The JBL AC115S-WH 15-inch subwoofer is the white-finish version of JBL's passive, high-power install subwoofer, engineered to add deep, controlled low-frequency reinforcement to fixed commercial sound systems. Built around a single 385 mm (15 in) long-excursion driver in a vented, front-loaded enclosure, it extends system bandwidth down to 32 Hz for full-range music and speech reproduction. As part of JBL's AE Application Engineered Series, this commercial subwoofer for fixed installation is designed to pair with AE Series full-range loudspeakers and external amplification. Twelve M10 suspension points make it a practical suspendable subwoofer for flown or ground-stacked deployment, and the white finish blends into light-colored architectural interiors.

Product Description

The JBL AC115S-WH 15-inch subwoofer uses one 385 mm (15 in) driver with a 75 mm (3 in) voice coil in a vented, front-loaded configuration that delivers high output with low power compression. Rated at 400 W continuous (1600 W peak, IEC) into an 8-ohm nominal load, this passive front-loaded subwoofer reaches a maximum SPL of 120 dB (126 dB peak) and reproduces a frequency range of 32 Hz to 250 Hz, making it well suited to bass extension for speech and music in commercial venues. The 18 mm multi-ply hardwood enclosure carries dual Neutrik NL4MP connectors plus covered barrier-strip terminals for flexible wiring, and a powder-coated perforated-steel grille with acoustically transparent foam backing protects the driver. As an AE Series subwoofer, it integrates cleanly with JBL AE full-range models and Crown or comparable amplifiers for a complete installed system. Twelve M10 threaded suspension points support rigging, and the larger 18-inch JBL AC118S-WH subwoofer is available where greater output and lower extension are required.

What full-range loudspeakers does it pair with?
It is designed to integrate with JBL AE Series full-range models for a tonally matched system. A processor or amplifier with crossover capability should be used to set an appropriate low-pass point.

Can the AC115S-WH be flown or suspended?
Yes. The enclosure includes 12 x M10 threaded suspension points for flown or stacked installation. Use JBL-approved rigging hardware and follow a qualified rigging plan.

Is the white finish the same product as the black AC115S?
