Intelligent by Design

One of the coolest things about active loudspeakers is the lack of back-breaking racks of amps, crossovers and EQs that are often required to make passive speaker systems sound almost as good. But that comes with a trade-off—that extra weight is transferred to the loudspeaker, making it difficult for a single user to heave all that mass onto the top of a speaker stand. BEHRINGER EUROLIVE D Series' “Intelligent-Design” merges the best features of active loudspeakers with significantly lower weight through the use of switch-mode power supplies (SMPS) and Class-D amplifier topology.

Class-D Amplifier Technology Delivers High Power With Low Weight

Instead of operating relatively continuously like Class-AB circuits, Class-D amps switch on and off thousands of times per second, delivering power only as it is needed. In other words, the  amplifier is either fully on or fully off, which significantly reduces the power losses in the output devices. Although we didn't invent Class-D technology, our R&D Department has spent years perfecting our own version with all the benefits of reduced weight and cool running—and none of the drawbacks.

Massive Power to Size Ratio

At the heart of each B615D and B612D are two high-current amplifiers with a combined maximum output of 1500 Watts. These Class-D amps are capable of driving the speakers to their maximum without damage or distortion thanks to their internal active protection circuits. Put simply, these systems will astound you with their massive punch, smooth midrange and articulate top-end.

Custom-Designed Transducers

Let's face it; the transducers (woofers and tweeters) are the only part of a sound system you actually hear, so we never cut any corners here. While some of our competitors are content to buy off-the-shelf transducers and plug them into their boxes, we custom-design and build ours from scratch. We wind the voice coils, process the paper pulp into cones—and even machine our own back plates. This enables us to control the quality, and frankly to make better components, like the long-excursion 12 and 15" LF transducers and state-of-the-art 1.75" titanium-diaphragm compression drivers we load into each and every B612D/B615D.

Instant PA System

With just a single EUROLIVE D Series loudspeaker and a microphone you can set up an instant sound system. Thanks to the built-in preamp section, you just connect a dynamic mic and raise and lower the volume with the Level control. Place the speaker on a tabletop or stand, and power up. It's just that easy. And if you need more coverage, say for a larger room or audience, you can add more active loudspeakers via the convenient Link Output XLR connector. 

Stereo Music System

You can even use two D Series enclosures for stereo playback of your music sound files without any additional hardware. Just plug the appropriate stereo “breakout” adapter into your deck's output jack and run the cables to the 1/4" inputs on each loudspeaker. Set the Level and EQ controls the same on both enclosures. Voilà, instant party! 

Marvelous as Monitors

Thanks to their trapezoidal design, these cabinets can be laid on their side providing the ideal angle for onstage monitor wedge applications. Hookup is simple, requiring only a single XLR or 1/4" cable from the monitor send on your mixing console and power. Additional monitors can be chained together via the XLR Link Output jack on the rear panel.

Powerful Low Frequency Response

The EUROLIVE D Series was built with extended low frequency handling in mind. Thanks to their internally braced, injection-molded, tuned-port enclosures, these bad boys really crank out serious quantities of bass. Keep in mind that bass response varies according to LF transducer size, so the larger the speaker, the more bass you will be able to generate. 

Articulate Midrange and Treble

Even if your particular application doesn't include booming bass, you'll love the sheer accuracy of these loudspeakers. Over a year went into designing an exponential horn/titanium-diaphragm compression driver combination that could handle serious hard rock or dance music—yet also satisfy audiophiles with its musical timbre and attention to detail. For spoken word, singing or acoustical instruments, the EUROLIVE D Series is un-matched for its ability to articulate complex harmonic content. In fact, many customers say these are the most natural-sounding speakers they've ever heard, even when compared to systems costing much more.

Processor Controlled Output

Hidden deep inside each enclosure is the equivalent of an active 2-way electronic crossover, graphic EQ, parametric EQ, mic preamp, limiter and two Class-D power amplifiers, yet overall weight is less than comparable loudspeaker systems. These components work together seamlessly to provide optimal sound quality without you ever having to touch a single knob. As output demands rise, the internal processor frees up LF amp and transducer resources by reducing program bass content, so that higher overall system volume can be realized. It's like having a tiny soundman inside each cabinet constantly monitoring and changing output parameters for the best possible sound.

Which Speaker Should I Buy?

Well, let's start with your application… are you giving a speech in a hotel ballroom—or rocking out at the local bar or dance club? Whether to choose one speaker cabinet over another depends on your bass requirements. A 15" woofer has about 40% more surface area with which to move air than a 12" and that translates into more bass. So if you're addressing a meeting, or jamming at the local blues joint, the B612D might be all you'll ever need. But if you're providing disco in a busy nightclub, hosting Karaoke night in your living room, or just want a little more “thump”, then the B615D may be a better choice.

Sound Value

EUROLIVE active PA loudspeakers stand head and shoulders above the rest of the pack and deliver exceptional performance, even when pushed to their limits. Lightweight and powerful, with built-in mixers, 2 band EQ and custom-designed transducers, B612D and B615D active loudspeakers are ideal for both speech and music applications—at a price unheard of in this class.
