Core 47

No more second-guessing

Let’s start at the top. Dynaudio studio monitors have always been famous for their revealing detail. The Esotar Pro tweeter takes the word ‘revealing’ to a new level. It’s the culmination of our engineers’ obsessive attention to driver detail, and uses innovative airflow technology (as well as a powerful neodymium magnet) to ensure that what went in, comes out.

Advanced manufacturing techniques and extensive measuring in our Jupiter testing facility have resulted in the ingenious Hexis inner dome. It sits just behind the tweeter diaphragm and optimises airflow to improving thermal response and eliminating unwanted internal resonances. The result is the best imaging, transient detail, and effortless high frequency response. It’s the kind of tweeter you can listen to long into the night during marathon mix sessions. Full detail and clarity, but no fatigue.

The 4in midrange driver provides staggering detail. It uses our proprietary MSP (Magnesium Silicate Polymer) material in its one-piece cone for the perfect balance of lightness, stiffness and damping. That, coupled with an aluminium voice-coil and neodymium magnet system, means an incredibly fast response and authoritative control. With crossover points at 475Hz and 5.25kHz, Core 47 delivers so much more of the critical vocal range in one driver than typical designs, ensuring your mix decisions on vocal balances and dialogue subtleties are made with confidence.

Core 47 and Core 7 share the same woofer. However, in a three-way design, this driver can focus on delivering deeper bass since midrange duties are handled by the 4in driver. This helps deliver the lower frequencies deliver awesome clarity, while the amplifier’s power and gentle roll-off let your ears (and your recordings) take full advantage of all the depth on offer. And, most importantly, all this deep energy is tonally accurate, letting you equalise bass instruments, kick drums, and all those subwoofer “booms” in the movies.

And because each driver is handmade in our factory in Denmark (we produce 1.4 million drivers each year for our home hi-fi, custom-install, in-car and pro-studio speakers), we can maintain incredibly small tolerances and deliver exceptional imaging. This consistency in each driver means you can use Core monitors in multiple studios and have them all sound and perform at the same high level – everything you need to hear, everywhere you go.

Under the hood: brains as well as brawn

The Dynaudio AIR series was famous for its advanced DSP system. But times have changed, and our acoustic engineers are restless folk… so they’ve spent the intervening 18 years innovating. That’s resulted in some great leaps in DSP sophistication – but also in the way it’s applied in everyday use. You wanted something easier to use, and that’s exactly what you’ve got – with even better performance.

We’ve given Core 47 the power to optimise itself for differing acoustic environments. There are three settings: Anechoic, for when the monitors are placed on stands in rooms that have sufficient dampening treatment (such as recording studios and dubbing stages); Desk, for when they’re on a workstation or meter bridge; and Soffit, for when they’re mounted in properly designed wall soffits as part of an overall architectural acoustic design. And that’s not all: you can also set boundary filters that compensate for walls or corners where low-frequency room modes can be triggered.

We’ve marked the speakers ‘left’ and ‘right’, but tweeter position depends on your room. Core 47 can be used tweeters-in or tweeters-out, depending on the room and listening position.

Users can also alter the overall presentation. Core 47 uses the same concept as the LYD series Sound Balance filter – a different design from the typical tweeter and woofer adjustments found on most active monitors. Instead of simply adjusting the level of the tweeter up or down, which will affect phase response, Core 47 uses a full-spectrum band-pass filter that tilts depending on the desired tonal response. In the ‘Dark’ setting, the entire frequency response is tilted so that 20kHz is down -1.5dB while 20Hz is up +1.5dB. In the bright setting, the tilt is reversed (+1.5dB at 20kHz and -1.5dB at 20Hz). This gentle filter, unlike traditional shelving EQs, maintains the proper phase response between the drivers while providing the tone that meet your tastes.
