Behringer B1500XP 15″ Active PA Subwoofer with Stereo Crossover
Behringer B1500XP is an active PA subwoofer designed for low-frequency reinforcement in live sound and playback systems. It enables extended bass reproduction for performers, DJs, and audio operators, supporting full-range PA workflows. This makes it ideal for live events, mobile DJ systems, and installed sound setups where controlled sub-bass output is required.
The system uses a Class-D amplifier paired with a 15″ Turbosound low-frequency driver 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, crossover alignment, and phase settings for system tuning. The enclosure includes transport handles and a pole mount socket to support portable PA deployments.
