JBL ASB6125-WH - 6400W 2 x 15-inch Passive Front Loaded Installation Subwoofer in White Finish

The JBL Professional ASB6125-WH is a high-power, 6400W passive subwoofer designed to deliver extraordinary bass performance across a variety of professional audio applications. Equipped with two JBL 2265H-1 Differential Drive dual voice coil, dual gap 15-inch woofers, the ASB6125-WH is engineered to produce deep, impactful bass with remarkable clarity and minimal distortion. The drivers are designed with neodymium magnets and ultra-durable cones, ensuring long-term reliability and high performance even under the most demanding conditions. The ASB6125-WH is part of JBL's AE Series, a versatile family of loudspeakers that are ideal for both ground-stacked and suspended applications in venues like performing arts facilities, auditoriums, houses of worship, live clubs, sports arenas, and themed entertainment venues.

The subwoofer's enclosure is constructed from 16 mm (5/8-inch) exterior-grade 11-ply birch plywood, ensuring a sturdy and acoustically efficient design that minimizes unwanted resonances. This rectangular enclosure is coated with JBL's rugged white DuraFlex finish, offering both aesthetic appeal and durability for long-term performance in both indoor and outdoor environments. The subwoofer features a powder-coated 14-gauge perforated steel grille, lined with acoustically transparent foam, providing driver protection while preserving sound quality. The ASB6125-WH includes 16 M10 threaded suspension points (four on the top, four on the bottom, and four on each side), allowing for secure mounting and integration into custom array configurations. Pre-engineered array bracketry is available for seamless integration into large sound reinforcement systems.

Performance-wise, the ASB6125-WH excels with a frequency range of 32 Hz to 1 kHz (-10 dB) and a frequency response of 38 Hz to 1 kHz (±3 dB), making it capable of producing the extended low-end frequencies needed for powerful, clean bass in large venues. The subwoofer can handle 1600W of continuous pink noise (6400W peak) for 2 hours, and has a long-term power rating of 1350W (5400W peak) over 100 hours, ensuring consistent output under demanding conditions. With a maximum SPL of 132 dB (cont avg) and 138 dB (peak) from 35 Hz to 400 Hz, the ASB6125-WH is capable of filling large spaces with deep, powerful bass. The system sensitivity is 100 dB at 1W (2.0V) @ 1m, allowing for maximum output with minimal power usage.

For flexible integration into large systems, the ASB6125-WH features a Parallel/Discrete switchable input mode, allowing users to choose between parallel or discrete driver configurations. The subwoofer's FIR tuning ensures that the phase profile is optimized to match full-range models, providing seamless integration and consistent sound coverage across the entire system. The subwoofer operates with a nominal impedance of 4 ohms in parallel-drive mode and 2 x 8 ohms in discrete-drive mode, making it compatible with a wide range of amplifiers. The input connectors include both NL4 Neutrik Speakon and CE-compliant barrier strip terminals, which accept up to 10 AWG wire or 9 mm (0.375 in) spade lugs. The Speakon connectors are in parallel with the barrier strip, facilitating loop-through functionality in multi-subwoofer setups. The ASB6125-WH is also rated to Mil-Std 810 and features an IP>3 rating per IEC529 for protection against dust and water, making it suitable for both indoor and outdoor environments.
