Behringer B1800XP Eurolive Active Subwoofer

Behringer B1800XP Eurolive — 3000W Active Subwoofer

The Behringer B1800XP Eurolive is a powered PA subwoofer engineered for small and mid-sized live rigs where deep, hard-hitting bass matters. An 18" Turbosound long-excursion driver and a 3000W Class D amplifier deliver the clean headroom needed for sustained kick drums and bass-heavy electronic music. The compact Class D topology keeps the cabinet manageable for mobile setups, and this model integrates with any Eurolive 2-way loudspeaker without external crossover processing.

Turbosound Transducer and Active Stereo Crossover

The British-designed Turbosound long-excursion LF transducer absorbs the full 3000W amplifier output without losing definition. An onboard active stereo crossover splits the signal between sub and full-range tops, eliminating external processing, while intelligent limiter circuitry protects the woofer and thermal protection guards the amp during long sets.

Driver Power and Amplification

Clean low end depends on driver and amp pairing.

• LF Driver Size: 18" — Turbosound long-excursion transducer moves serious air for chest-rumbling bass
• Amplifier Class: Class D — efficient, cool-running topology lighter than older Class AB designs
• Peak Power: 3000 W — enough headroom to drive many clubs and mid-sized venues without clipping

Low-End Extension and Output Level

How deep and how loud a sub can play depends on its frequency response and max SPL.

• Frequency Response: 40 Hz – 150 Hz — reaches into sub-bass territory for kick drums and electronic bass lines
• Max SPL: 129 dB — keeps up with full-range tops in medium to large rooms
• Crossover: Active stereo with high-pass outputs — splits sub and tops without external processing

Connectivity, Controls, and Cabinet

Inputs, tuning controls, and physical dimensions determine how easily a sub drops into an existing rig.

• Inputs/Outputs: 2× XLR/TRS combo in, 4× XLR thru out — loop-through to full-range Eurolive tops and additional subs
• Tuning Controls: Tunable Bass Boost, variable high-cut, Phase switch — shape the low end to suit room acoustics
• Cabinet: 703 × 549 × 554 mm, 44.9 kg, built-in pole socket — fits standard sub slots and supports a full-range speaker on a pole above
