Behringer B1200D-PRO 500W 12" Active PA Subwoofer with Stereo Crossover

Behringer B1200D-PRO is an active PA subwoofer designed for low-frequency reinforcement in portable and installed sound systems. It enables extended bass reproduction for performers, DJs, and audio operators, supporting full-range PA workflows. This makes it ideal for live performances, mobile DJ systems, and event sound setups where controlled low-frequency output is critical.

The system uses a Class-D amplifier paired with a long-excursion low-frequency transducer to reproduce sub-bass frequencies. A built-in stereo crossover routes high-pass filtered signals to connected full-range loudspeakers.

Integrated controls allow adjustment of bass boost, phase alignment, and crossover settings for system tuning. The enclosure includes a pole mount socket and transport handles to support portable PA deployments.
