Behringer Eurolive VQ1800D Active 500 Watt 18 Inch PA Subwoofer

The Behringer Eurolive VQ1800D brings professional-grade bass performance to your PA setup with its powerful 18" active subwoofer design and 500-watt Class-D amplification. This compact powerhouse features a custom-built long-excursion transducer with high-temperature voice coil, engineered to reproduce ultra-low frequencies with remarkable accuracy and punch. The advanced Class-D amplifier technology operates with superior efficiency compared to traditional Class AB circuits, running either fully on or fully off to minimise heat generation and eliminate the need for heavy heat sinks.

Behringer’s commitment to quality extends to every component, with transducers custom-designed and manufactured in-house from voice coil winding through to paper pulp processing and back plate machining. The built-in active stereo crossover provides high-pass filtered outputs for your full-range speakers, while comprehensive connectivity options include balanced XLR inputs, outputs, and thru jacks for daisy-chaining multiple enclosures.

Fine-tuning your low-end response is straightforward with the VQ1800D’s professional control set. The Boost Frequency knob targets frequencies between 40 Hz and 90 Hz with an optional +6 dB boost, while the High Cut dial manages the upper corner frequency from 70-150 Hz specifically for the subwoofer amplifier. Additional controls include input level adjustment, phase switching to prevent frequency cancellation with satellite speakers, and status LEDs for power, signal presence, and limiting. The rugged construction features ergonomic handles, steel protective grille, and a pole socket for commercial mounting applications.
