Our EUROLIVE VQ1800D 500-Watt active subwoofer provides the ultimate in low-frequency reproduction, and the built-in stereo crossover makes it ideally suited for use with any of our active 2-way loudspeakers. Packed with a powerful 500-Watt Class-D amplifier, 18" long-excursion Low-Frequency (LF) transducer and an incredible array of professional features, the VQ1800D produces extreme levels of low-end punch, with the definition and clarity typically reserved for much larger systems!\n\nPut simply, these cool-running systems are much lighter, making them ultra-easy to transport and set up – and our no-compromise design means you get amazingly-deep, chest-pounding bass that will keep the party going all night long.\n\nClass-D - Massive Power, Perfect Sound\nThanks to our revolutionary Class-D amplifier technology, we are able to provide you with enormous power and incredible sonic performance in an easy-to-use, ultra-portable and lightweight package. Class-D amplification makes all the difference, offering the ultimate in energy efficiency and eliminating the need for heavy power supplies and massive heat sinks. This amazing technology makes it possible to design and build extremely powerful products that are significantly lighter in weight than their traditional counterparts, while using less energy and protecting the environment.\n\nCustom-Engineered Transducers\nPowerful, high-efficiency Class-D amplifiers and Switch Mode Power Supply technology coupled with state-of-the-art DSP functionality sure sounds impressive – but what about the part of the system you actually hear? We never cut corners on our transducers (woofers and tweeters), and we never just pull what we have off the shelf. Our LF transducers are designed specifically for each application – it’s what sets us apart from the competition. When you buy a BEHRINGER active subwoofer, you can rest assured that the transducer inside has been engineered to perform flawlessly with every other element for truly professional results. The VQ1800D active subwoofer is capable of extremely high sound pressure levels: 124 dB (Full Space, 1 W @ 1 m), with a frequency range of 40 - 200 Hz.\n\nTake Control\nThe VQ1800D features balanced XLR inputs and outputs, as well as balanced XLR Thru jacks for connecting additional enclosures. A Boost Frequency knob targets a boost frequency between 40 and 90 Hz. Flick the Boost switch to give your selected frequency a +10 dB boost. The VQ1800D also has a High Cut dial that provides precision control over the upper-corner frequency of the subwoofer’s amplifier. The High Cut dial does not affect the Thru signals, only signals directed to the subwoofer (however, it does affect the Output socket signals sent out to full-range speakers). A Level knob controls the input gain, and the Phase switch reverses the output phase to compensate for frequency cancellation between the subwoofer and satellite speakers. LEDs show operational status at a glance, including power, signal present and input overloads.\n\nWhich Speaker Do I Need?\nAs you have probably noticed, we make these subwoofers in two different woofer sizes. Which one is right for you? An 18" woofer has more surface area with which to move air than a 15". If you’re running sound for a jazz combo in a dinner club, a single VQ1500D might be all you’ll need. But if you need to serve up pulse-pounding techno at a large, standing-room-only dance club, you might need a pair of VQ1800Ds to really ignite the dance floor.\n\nSound Value\nThe VQ1800D PA subwoofer stands head and shoulders above the rest of the pack and delivers exceptional performance, even when pushed to the limit. Lightweight and powerful with custom-designed transducers, 500 Watts of Class-D output power and a state-of-the-art onboard active stereo crossover, the VQ1800D is ideal for any music application – at a price that is unheard of in this class.\n\nExperience the EUROLIVE VQ1800D at your local dealer today and find out why more and more professionals are turning to BEHRINGER EUROLIVE active subwoofers for their superb performance and extraordinary value.
