Hifi Test Loudspeaker Yearbook 2013

“The Ardora is currently controlled by one of the most advanced speaker management systems, the HD2 from Four-Audio. […]
This makes everything possible: from a frequency response that is drawn perfectly as with the ruler, to desired sound images – of course only at the customer’s request.”

Conclusion: “So soon after the wonderful Ardora, Audiograde adds one with the active version: the speaker itself didn’t have to get any better – thanks to its perfect adaptation to the listening room, it now plays at a level that you just have to listen to to believe it.”
