The JBL ASB6112 is a compact yet powerful single 12-inch active subwoofer engineered to deliver robust low-frequency extension for mobile DJ, small-to-medium venue, and compact installed sound applications. This powered subwoofer integrates a high-output 12-inch driver with a purpose-matched, high-efficiency amplifier and onboard digital signal processing within a portable, durable enclosure. The system is designed to provide punchy, articulate bass in situations where space and setup time are limited, but performance cannot be compromised.

The integrated amplifier and DSP are specifically tuned to optimize the driver's performance within the vented enclosure design. This processing includes precise crossover filters, speaker protection limiters, and corrective equalization to ensure reliable operation and optimal sound quality. The active design simplifies the user's audio chain by eliminating the need for an external amplifier and crossover, offering a straightforward solution for extending the low-end response of a full-range speaker system.

Built with a rugged plywood cabinet and a coated, textured finish, the ASB6112 is designed to withstand the demands of regular transport and use. It features integrated handles and a form factor that allows it to be easily stacked or placed beneath a main loudspeaker. Comprehensive connectivity includes balanced XLR and combo jack inputs, along with pass-through outputs for sending a filtered signal to a satellite speaker. This subwoofer provides a practical and powerful low-frequency foundation for a wide range of professional portable audio systems.
