Behringer VQ1800D Eurolive 500W 18" Powered Subwoofer

The Behringer Eurolive VQ1800D is a professional powered subwoofer designed to add deep, controlled bass reinforcement to PA systems. Its 18-inch long-excursion transducer, paired with a high-temperature voice coil, is engineered to reproduce ultra-low frequencies with accuracy and impact — delivering the chest-thumping punch that live music, DJ performances, and event sound systems demand. The onboard 500-watt Class-D amplifier provides efficient power delivery with lower heat generation than conventional amplifier topologies, while built-in protection circuits for over-excursion, thermal overload, and clip limiting help ensure reliable operation even during extended, high-output use.

One of the VQ1800D's most practical features is its built-in active stereo crossover, which provides high-pass filtered outputs for your full-range loudspeakers. This means you can route your audio signal through the subwoofer first, letting it handle the low frequencies while sending a clean, bass-managed signal to your tops — all without needing a separate external crossover unit. A variable high-cut filter gives you control over the crossover frequency, and a phase switch lets you align the sub's output with your mains for coherent coverage. XLR inputs and outputs keep the signal chain fully balanced and professional. For performers, DJs, and sound engineers looking for reliable low-end reinforcement with straightforward system integration, the VQ1800D delivers solid performance in a self-contained package.
