Ultra-Linear Frequency Response

Home- and project-studio engineers are often frustrated due to studio mixes that fall flat when played through car speakers or a home stereo. Most consumer audio systems are tuned read more to anticipate what listeners like, and compensate for less-than-ideal listening conditions. A little extra bass in the control room can lead to boomy muddiness in the car. Too much treble becomes shrill and brassy when those frequencies are boosted yet again. The B2031A's ultra-linear frequency response from 50Hz up to 21kHz assures you're hearing your music, not the monitors. The pair is shipped with individual frequency diagrams so you'll know exactly what to expect. When your mix is right, consumer audio systems will enhance your songs instead of pushing them past their limits.

Punchy Bass

Most small studios are outfitted with bookshelf-style nearfield monitors to conserve space. With small-format cabinets, faithful bass response is particularly important. When you're trying to capture the rumbling thunder of the bass guitar, that big 15-inch sound has to come out of a much smaller driver. Behringer's 8.75-inch long-throw woofer is pushed by a dedicated 150-Watt amplifier for tight, articulate lows, even at high SPLs. You can crank these babies up to 116 dB, much louder than you'll ever want to mix at, and still hear individual bass notes with clarity and presence. With the groove firmly established on the recording, it will be much easier for your audience to connect with your music.

Natural Highs

High frequencies are produced with a one-inch Ferrofluid-cooled dome tweeter. The sound is transparent and airy to save wear on your ears and create a more natural listening experience. Nothing kills a mixing session faster than fatigue brought on by harsh highs. These speakers let you mix longer and with more focus, for speedy completion and sparkling results. The powerful 75-Watt tweeter amplifier will push guitars, vocals, and cymbals up above the groove, so you can position each sound in its own space through the stereo field. As a part of the front bezel, Behringer's waveguide technology controls the high-end dispersion for a well-defined stereo image and a massive sweet spot. You can pan the drums across the entire spread for 70's style tom rolls, or tighten them up for a more authentic, true-to-life drum sound. You'll hear exactly where everything sits and make precise adjustments instead of hoping for the best. Individual instruments won't have to compete for attention in the mix. You can blend all the sonic elements to work together, just like the pros do.

Active Crossover Network

Advanced electronics help manage every frequency in the spectrum for the most efficient playback of your music. The 2kHz active crossover network uses fourth-order Linkwitz-Riley filters for the smoothest midrange transition between the woofer and tweeter. Each frequency is reproduced by the most capable driver for tight, controlled audio from low to high. This reduces unwanted distortion and boosts clarity, so each sound comes through the mix just as you intended.

Quality Construction

Servo-balanced XLR and 1/4-inch TRS inputs prevent noise from entering the signal path. Electrical hum and radio frequency interference are rejected, keeping your mix clean from the board to the cabinet. The die-cast chassis resists deformation at high volume and cuts down on mechanical noise from internal resonance. The cabinet is built with environmentally friendly E1-MDF material for its rigidity and vibration dampening properties. All these elements work together to provide you with tight, accurate sound, regardless of the type of music you mix. From the sickest metal to the slickest pop, it all comes through loud and clear.

Room Compensation and Magnetic Shielding

Nearfield monitors usually sound their best with at least eighteen inches of air between them and the nearest wall. Home-studio engineers know this isn't always practical, though, because of the space constraints. Fortunately, B2031A's have a room compensation switch to let you tailor the mix to any studio layout. You can place them up against a wall or even in a corner if you have to, and still get accurate playback. No more guessing on your fader moves, only to find out later you made the wrong choice. Since many small studios are designed around a computer recording solution, Behringer magnetically shielded these monitors to protect your CRT screens and hard drives from damage. Whether you use an old reel-to-reel tape system or the most modern digital platform, your 2031A's will fit right in.

I'll start off this review by noting I've been using these monitors now for 7 years, so I'm not some excited newbie I'm actually a guy that's been recording for about 17 years now and have had this product for 7 years. I'll start by noting how flat these are. They are perfect in that whatever I play on them that sounds bad sounds bad on all other systems. Whatever sounds good translates to sounding good on other sources. Being I've had mine so long I have to rate the quality very high as I've had ZERO problems with mine - no joke... not one problem, though I've read some horror stories from some owners. That being said I'd like to note I've read some slight speculation on the net that the older models, such as mine, are far better in quality than the more current models... again though that is purely specualtion from 1-2 people. I've tried upgrading, cause we all want the supposed "best" no? I've tried Dynaudio BM15A's, Mackie HR824's (MK1 & MK2) and I keep coming back to these and returning the others. I will say, the new Mackies are awesome but the bass is just way too much for a "half-space" setup, meaning a setup where there's a wall right behind your speakers. The room acoustics need serious treating due to the Mackies low end response and that costs thousand in serious bass trap to fix the problem. I don't have this problem with the Behringers, yet I still have great tight punchy low end, just not as low as other brands go. In all read more honesty though most consumer listening sources don't have a good accurate sub 50hz response anyway. I don't know what else to say about them. I mean, they're flat, they're super accurate, they're super inexpensive, and I've had mine for 7 years and they're still going strong. Your mileage may vary of course so you're on your own. But after all this time I thought, "Why didn't I ever write a review? After all this time I think I have something valuable to contribute".
