Dynaudio位于丹麦的研发中心，2018年部署了Jupiter音箱测试系统。一次完整测试只要20分钟，其他公司的传统测试方法，完整测一次要2周。

The appliance of science

The system allows for a huge number of measurements. That robot? Mounted with 31 microphones at 6° intervals, it measures 180° of sound in a single go. The arc can rotate, and the stand that the test subject is on rotates too, allowing for 360° of measuring. The software that drives Jupiter is an in-house creation by Dynaudio’s engineers.

The importance of rigorous, scientific testing shouldn’t be underestimated. “Measurements are indispensable in audio,” says Daniel. “Anyone who says they’re not necessary is ignorant. We need a lot of data to estimate the range of use of a driver.”

But, he adds, experienced ears are still critical to the end product: “Two equally flat curves made with different crossover topologies could sound quite different – here, the engineer’s expertise is a major part of a successful speaker.”

Testing that took weeks now takes days, and testing that took days has turned into minutes. And, you could argue, that’s a double-edged sword in the hands of perfectionists – the temptation is to tweak, and tweak and tweak (and tweak), in the name of an ever more perfect speaker. A better product. Something of infinitely high quality to grace the living rooms of the world’s most demanding hi-fi listeners.

“We run out of time,” says Alex. “There’s always something else you can do.” Everything from the cabinet size to the supplier of the internal damping material is up for grabs, and every test performed by Jupiter and its team of engineers yields interesting, actionable results. “That’s why it’s good to have a deadline,” says Alex. “It forces you to finish it.”

A good engineer is never satisfied. We all know that. But that’s the way they like it. “I wouldn’t be doing this any more if I was satisfied,” he tells us of his constant quest for audio excellence. “If I was, what would I be trying to achieve after that?”

Alex and his cohort of engineers might lament that they’re not allowed to test forever, constantly whittling, refining, testing and repeating until the process yields a speaker that produces details even the most detail-oriented producer would never imagine. But their loss is our gain, and with the Evoke systems locked and ready to ship, they can move on to the next set of incredible Dynaudio products.

In the ears of our engineers, nothing will ever be perfect – but Jupiter allows us to get breathtakingly close.
