The World’s Most Popular EQ

If you’ve ever adjusted the bass and treble on a hi-end stereo system, a boom box or even a car stereo, then you’ve used a Baxandall EQ. Originally designed by the now legendary electronics designer Peter Baxandall, these are the world’s most popular EQ curves for a good reason: they are able to improve the sound of anything you throw at them. The Dangerous BAX EQ is the first professional, stand-alone EQ to use the famous Baxandall curves, and our version – designed by our own legendary designer Chris Muth – has become an instant classic among mixing, mastering and tracking engineers. It’s so loved, in fact, that most are leaving it patched into their audio path full time where it sweetens and deepens all kinds of music…day in, day out, all year long.

Big Moves and Broad Strokes

At the heart of this stereo unit are gently sweeping treble and bass EQ shelves (the Baxandall Curves) that give you subtle yet profound control over wide sections of the frequency spectrum. The opposite of a surgical tool, the BAX EQ is all about sweetening sounds with broad, musical adjustments. Starting far below and above the human hearing limit, the broad and gentle EQ curves gently tug at the audible frequencies in ways that other EQs cannot. This unique design provides a distinctively sweet and open treble along with a powerful and three-dimensional low-end you simply can’t get out of other EQs.

The Paradox of Transparency

The bass and treble shelves found on most professional EQs introduce phase delay and other audible artifacts, sometimes called “color.” The BAX EQ’s shelves maintain phase coherence, and — because it is built from the same ultra-high-grade components we use in all our equipment — the BAX EQ does not change the characteristics of the original sound. This is the ineffable paradox of real analog transparency: you have the ability to make powerful changes without substantially altering the original sonic characteristics. Rather than adding more color, you’ll hear the original colors more beautifully, more openly and more powerfully, no matter how far you push it.

Sophisticated Filtering

Beyond the easy-to-use shelf controls, the BAX EQ is equipped with sophisticated filtering options that vastly expand its versatility. The cut filters on either end of the spectrum dial out unneeded frequencies that will be boosted at the far end of the shelves. On the low end, you can cut below 12 Hz, where headroom-eating, infrasonic rumble and DC-offset live. On the high end, you can dial out ultra-sonics like 70 kHz that can carry out-of-band noise that translates as harshness in many A/D converters. And when you start playing the cut filters against the shelves, a whole world of unique tone-shaping opens up within the audible frequency band – sounds you wont get anywhere else.

Effortless Results for Tracking, Mixing & Mastering

In a category all its own, the BAX EQ will compliment any studio configuration. Outstanding in a mastering rig, on a whole mix or in any tracking chain, the BAX EQ lets you effortlessly sweeten and deepen any music — like the best bass-treble controls you’ve ever used.

  • Mackenold Jean Louis

    Composer, Artist Songwriter and Mix Engineer

    “As an owner of the 2-BUS, BAX EQ, the MONITOR ST and the DAC-ST I have to admit my mixing has more depth, very clean and more headroom than I infrequently get ; most importantly it feels as if my mixings are done from a $2 million console. I am quite content with my work these days. I am a huge fan of the Dangerous’s gear, every piece is well thought of sonically and well physically design.”

  • F. Reid Shippen

    Mixing Engineer

    “I tried it on a mix and once I heard what it could do on the stereo buss I said ‘Oh man, I need to revisit a couple of the other mixes that I’ve done and put this on all of them’ – and I actually ended up doing that!”

  • Phil Demetro

    Mastering Engineer, Laquer Channel Mastering

    “The BAX EQ is unlike anything you have heard, but exactly like what you۪’ve been looking for.”

  • Simon Li

    Mixing/Mastering Engineer - nOiz

    “Very musical and super clean. The HPF is the best I’ve used and it’s an excellent tool for problem solving.”

  • Glenn Bucci

    Engineer, Revelation Sound Studios

    “Pure Magic! The BAX EQ was amazing in gently removing the low end 30Hz and below, adding a little more punch in the low’s at 84 Hz, and bringing the guitars and keyboard forward and a little fresher at 2.1 kHz and removing unwanted high end with using the filter at 28 kHz.”

  • Mike Wells

    Mastering Engineer

    “The cutting filters are a fantastic addition on top of the cut and boost shelving filters. I use the BAX EQ every day, I can’t really say there isn’t any master that I make that doesn’t have the BAX on it now!”

  • Antoine “Chab” Chabert

    Mastering Engineer

    “I also use the BAX EQ for cutting Vinyl records, I have one in my mastering room and one in my vinyl cutting room, it۪’s really perfect for reshaping the music for vinyl.”

  • Fab Dupont

    Mix Engineer

    “The BAX EQ is my new favorite box to put across my whole mix.”

  • Claude Zdanow

    Engineer, CEO and Found of Stadium Red

    “Stadium Red Engineer Ariel Borujow’s [mix] chain is: out to the 2-BUS LT, to an SSL compressor, then to the BAX EQ. He swears by it, he won۪t mix any other way.”

  • F. Reid Shippen

    Mixing Engineer

    “The BAX EQ is an awesome piece of gear. I’ve been looking for years, maybe a decade, for an effective hi-pass filter that can take the infrasonic muck out of a mix, without destroying what’s going on in the bottom end. And the BAX EQ is the only one that I’ve ever found that can do that. Add a little bang back in, right in the kick drum area, like 74HZ, and it’s perfect. It’s killer.”
