Behringer Eurolive VQ1800D — 500W Active Subwoofer for Live PA

The Behringer Eurolive VQ1800D is a 500W Class-D powered subwoofer with a single 18" long-excursion transducer for live PA, mobile DJs, and club installations. The Class-D amp pushes the woofer down to 40 Hz (-10 dB) while keeping the cabinet manageable for one-person load-in. A built-in active stereo crossover with high-pass outputs lets the unit slot into a 2-way system. This 18-inch powered subwoofer suits bands, DJs, and small-venue operators needing serious low-end from a single cabinet.

Built-In Stereo Crossover and Optical Limiter

The built-in active stereo crossover with a fixed 100 Hz high-pass filter on the outputs, variable High Cut (70–150 Hz), and switchable +10 dB LF boost at 45–90 Hz eliminates external processing. An optical limiter protects the 18" driver.

500W Class-D Amplification — Efficient Power for Long Sets

Class-D topology delivers high output from a compact power supply, so this sub runs for hours at club-level SPLs without overheating.

• Amplifier Type: Class-D — high-efficiency switching design
• Total Output Power: 500 W Peak — drives the 18" driver to 124 dB max SPL

18" Long-Excursion Woofer — Deep Bass Down to 40 Hz

The custom 18" transducer uses a long-excursion voice coil rated for high temperatures, moving large air volumes without bottoming out.

• LF Driver: 18" / 45.7 cm woofer — single high-excursion transducer
• Frequency Response: 40 Hz to 200 Hz (-10 dB), 60 Hz to 150 Hz (±3 dB)
• Maximum SPL: 124 dB (half-space)
• Enclosure Type: Bass-Reflex — ported cabinet

Onboard Crossover, Phase Control, and XLR I/O

Balanced XLR inputs feed the internal crossover, splitting highs to satellite outputs and lows to the sub amp.

• Audio I/O: 2x XLR 3-pin inputs, 2x XLR 3-pin thru, 2x XLR 3-pin high-pass outputs
• High Cut Filter: 70–150 Hz variable — tunes the sub's upper corner
• Phase Switch: 0° / 180° reversible — compensates for cancellation with mains
• LF Boost: +10 dB at 45–90 Hz (switchable) — adds punch on demand
• Protections: Optical limiter, thermal, short-circuit, over-excursion
• Dimensions: 67 x 56.6 x 52.8 cm — Weight: 38.2 kg
