The Behringer B1800XP is a subwoofer designed to deliver an authoritative low-end output in large and medium-sized venues. Its 18" woofer, paired with the outstanding performance of a built-in Class D amplifier, provides a combination of punch and precision that rivals significantly more expensive models. The B1800XP is also packed with features that allow professionals to optimise their sound, with an integrated crossover that passes the signal on to mid and high-frequency speakers, which can be mounted directly on the sub here using an optional distance rod. And despite its versatility and capabilities, the unit is relatively lightweight.
The Behringer B1800XP's 3000W output is a real statement of intent – yet it can be powered from a standard IEC socket. With a maximum SPL of 129dB and a frequency range of 40 to 150Hz, this woofer is built to serve up an ample portion of bottom end. To start with, the audio signal is fed through a stereo input: The sound can be passed on unfiltered via Thru outputs, while the main outputs are equipped with a 100Hz filter to route the signal to mid-high speakers. All of these connections are implemented as balanced XLR sockets. For fine-tuning, the unit offers a boost control adjustable from 40 to 90Hz, a switchable high-cut filter sweepable from 70 to 150Hz (with a 24dB slope), and a phase reverse option. Last but not least, there are two carry handles to actually get the 45kg unit into the venue.
The Behringer B1800XP is a powerhouse built for pro sound crews. Production teams working in medium to large-sized venues get a tight, well-defined low-end without needing space for an external amp, as the power is already on board, and the box comes loaded with sound-shaping tools that allow pros to dial in the sub to match the rest of the FOH setup. Sound designers in turn can chase their ideal tone by experimenting with placement and flipping the phase. That kind of flexibility makes this sub a solid pick for rental companies too – as it pairs well with a wide range of top units.
The company, which was founded in Germany by Uli Behringer and now manufactures its products in China, has been known for affordable and great-value equipment since its very first product, the Studio Exciter F. An array of mixing consoles (such as the Eurodesk MX8000), signal processors, and later sound amplification and monitoring equipment, has made it possible for countless musicians to fit out their home studios, practice rooms, and mobile PAs within budget limits that were previously unthinkable. The acquisition of other companies, including Midas, Klark Teknik, and TC Electronic, meant that new product groups were added – and also resulted in the technical expertise of these companies being incorporated into product development.
The Behringer B1800XP is built for big live shows. Once the system is set up, sound techs will start by dialling the level down, switching off the booster and phase reverse, and setting the high cut to its maximum frequency – then they'll fire up the audio source and amps to fine-tune the sound. The B1800XP more than holds its own as a solo act, but bigger PA setups might want the full lineup, with multiple units on stage: Run these woofers in a pack and they'll deliver some serious low-end, perfect for bass-heavy gigs. For example, when running two subs, each sub's input can be fed the same mono signal from the sum, with their outputs passing the rest of the signal on to the PA's other components. And if the sub is going on the road, the Thomann cover specifically designed for the B1800XP will give it the protection it needs for the journey.
