Made in Denmark - How we build our drivers

Dynaudio designs and engineers all its drive-units in-house. We wouldn’t have it any other way… here’s why

We’re a fussy bunch. That’s why we design, develop and engineer all the stuff we make at our HQ in Skanderborg.

It’s always been this way, ever since we started in one building in 1977. Now we have 300 employees… and they’re all fussy. Just as it should be.

 

 

 

Our people are the key to everything we do: they know exactly how to create quality. They test, and listen, and test, and refine, and listen. They’re experts. It means if something isn’t right, we can change it – not just fix something else further down the line and hope it solves the problem. We go back and do it at the beginning.

 

 

Magnets and wires and robots

The driver sits at the heart of it all. We develop and manufacture them all ourselves – right down to magnetising the magnets and winding the voice-coils. Winding is an automated process these days (although even the robots we built can’t escape the eagle eyes or ears of our quality-control people), but at one point even this was done by expert pairs of hands.

We use aluminium wire instead of the more conventional copper: it’s lighter, which lets us pack in more windings, which gives more power, which lets us keep tighter control over the sound that comes from our diaphragms.

We make those in house too, from our own version of a material called MSP. We make the whole thing in one piece – including the dust-cap – so there’s no need for glue. (Although our engineers can tell the difference between different glues just by listening; never let it be said we don’t know how to have a good time.)

 

 

Building the motors

You might notice our cones are shallower than those of our competitors. That isn’t an accident, and it isn’t just because we want to be different. It’s to improve our speakers’ off-axis performance – so the sound you get off to the side is far closer to what you hear out in front… perfect if you have friends over and don’t want to give up the good seat.

There are other, less obvious details, too. Some you won’t even see – like the spider. That’s the springy piece of material that holds the voice-coil in place. It’s springy because it needs to control how much the voice-coil moves back and forth, and how much air there is behind the speaker cone. We’ve improved its symmetry by taking measurements and performing simulations – which improves the sound you hear.

It all sits in the basket. That’s the physical housing for the whole driver motor. The car around its engine (or, if you prefer, the bun around the delicious hot-dog). It’s just as important – so even though you can’t see it, we’ve spent just as much time refining its design as we have every other part of our speakers. Ventilation is crucial: it’s made to reduce turbulence behind the driver, which, again, helps them sound their best.

 

 

High-quality high frequency

Then there’s our signature soft-dome tweeters. We don’t let anyone else near them (apart from our talented, team, of course). We’ve been refining our tweeter designs ever since we started out: geometry, shape, materials, stiffness… even the coating. We use the right amount, in the right places, at the right density, to control roll-off and keep a steady hand on the treble response. And, because they aren’t made of metal, they have a flatter, more linear frequency response – and, we think, better sound.

But, in the end, it all comes down to our people. They’re fanatical about what they do (you really should check out one of our glue-listening sessions; they’re enlightening), and they’re incredibly proud of what they produce.

And, with our brand-new R&D facility opening at the end of 2016, they’re even more excited about what new stuff they can come up with next…
