Behringer B1200D-PRO Eurolive Active Subwoofer — Deep, Defined Bass for Live Sound

The Behringer B1200D-PRO Eurolive is a 500W active 12" PA subwoofer built to anchor small-to-medium live rigs with weighty, authoritative lows. Thanks to its efficient Class-D power amp and custom-engineered 12" long-excursion transducer, this model reproduces frequencies down to 45 Hz, all while remaining cool and light enough for easy load-in. Drop it into a 2-way system using the integrated active stereo crossover—no external processor needed. Mobile DJs, churches, and event techs benefit from tight, punchy bass without hauling oversized cabinets. The B1200D-PRO delivers a focused low-frequency foundation at a price point below many competitors.

What Makes This Subwoofer Distinctive

At the core sits a specially designed 12" long-excursion transducer, coupled with Switch Mode Power Supply technology for up to 122 dB maximum SPL from a cabinet weighing just 19.5 kg. Protection comes from an intelligent limiter, while the switchable Bass Boost lets users target a frequency between 45 Hz and 90 Hz with a +10 dB lift—tightening kick drum punch or extending sub-bass for club or dance floor use.

Class-D Power for Portable Performance

Instead of heavy transformers or bulky heat sinks, the B1200D-PRO’s Class-D amplifier keeps weight around 19.5 kg and draws less current, making single-person transport easy for gigs in clubs, worship spaces, or corporate events.

• Amplifier Type: 500W Class-D — high-efficiency switching design that keeps total weight low
• Maximum SPL: 122 dB (Full Space, 1 W @ 1 m) — suitable for small-to-medium venues
• Power Supply: Switch Mode Power Supply (SMPS) — ensures noise-free audio and global voltage compatibility
• Musicians can rely on the consistent output and efficiency of this amplification technology night after night.

Driver & Frequency Response — The 12" Transducer

Designed specifically for this cabinet, the 12" transducer features a high-temperature voice coil and rigid cone for reliable shape at high excursion. Its tight, defined character down to 45 Hz avoids the muddiness found in many entry-level subs. With a long-throw mechanism, the woofer moves more air per cycle, allowing just one B1200D-PRO to fill rooms up to 3,000 sq ft.

• LF Driver: 12" long-excursion transducer — designed for accurate, clean bass reproduction
• Frequency Range: 45 Hz – 180 Hz (-10 dB) — extends system low end well below most satellite cabinets
• Voice Coil: High-temperature voice coil — handles long, loud passages without thermal compression

Connectivity & System Integration

With the built-in active stereo crossover, the B1200D-PRO becomes a system hub: connect a stereo source to the balanced XLR inputs, route high-pass-filtered XLR outputs to a pair of active tops, and the subwoofer splits frequencies internally. The variable High Cut dial and Phase switch give you control over system alignment. Thru jacks pass full-range signal on to other cabinets for expanded setups.

• Crossover: Built-in active stereo crossover — splits signal to subs and tops without external processors
• Inputs/Outputs: Balanced XLR inputs, outputs, and Thru jacks — professional connectivity for a variety of PA setups
• Rear panel controls include Variable High Cut, switchable Bass Boost (+10 dB, 45–90 Hz), Phase switch, and Subwoofer Level for full system tuning.
• Protection: Intelligent limiter — prevents over-excursion and protects the woofer during peaks
• Pole Mount: M20 threaded pole socket — accepts standard poles for elevated placement of satellite speakers
