Behringer B1500XP — 3000 W Active Subwoofer with Turbosound LF Driver

The Behringer B1500XP is a high-performance active subwoofer for live PA reinforcement. At its core sits a British-designed 15" Turbosound long-excursion LF transducer, fed by a 3000-watt Class-D amplifier. The onboard active stereo crossover makes this model a drop-in partner for any active 2-way loudspeaker. A lightweight enclosure keeps the cabinet portable for one-person load-in at clubs, weddings and mobile DJ gigs.

What Sets the B1500XP Apart in Its Class

What makes this sub stand out is the Turbosound LF driver — a brand tied to major touring rigs and multiple Queen's Awards for Innovation — rather than a generic off-the-shelf cone. Class-D topology delivers 3000 watts while shedding the weight of conventional power supplies. An integrated RMS and Peak limiter protects the driver, while thermal limiting guards the amp during long sets.

Amplification and Power — Headroom for Demanding Venues

Class-D topology produces 3000 watts of clean output without the thermal mass of older designs. An intelligent limiter communicates with the woofer to prevent driver damage at peak levels.

• Amplifier Type: Class-D — efficient, lightweight, cool-running
• Power Output: 3000 W — substantial headroom for club SPL
• Protection: RMS limiter, Peak limiter, thermal limiting

Transducer and Acoustics — The Turbosound LF Driver

The 15" long-excursion Turbosound transducer is custom-engineered for this enclosure, with a voice coil and suspension built to absorb the full 3000-watt amp output without breakup.

• LF Driver Size: 15" — proven balance of SPL output and portability
• LF Driver: Turbosound long-excursion — British-designed for high-power handling
• Crossover: Built-in active stereo crossover — splits signal between sub and tops

Connectivity and Control — Tuning the Low End On Site

Balanced XLR inputs and outputs, plus XLR Thru jacks, let installers daisy-chain enclosures or feed satellite tops from a single sub. Front-panel controls cover common room-correction needs without external processing.

• I/O: Balanced XLR in/out, XLR Thru — flexible routing for stereo or mono PA
• Boost Frequency Range: 45–90 Hz — tunable Bass Boost with +10 dB switch
• Phase Switch: Reversible output phase — aligns sub with tops
