It's fascinating what changes are possible with advancing materials technology. Someday we'll be 3-D printing speakers at home from patterns we buy off the Internet, much like we buy music tracks and e-books now. One of the greatest things future listeners will enjoy is the fact that since physical speakers today are an inventory item and expense, there's only so much flexibility possible in getting an 'ideal' speaker to perform in a variety of rooms. In the future, the patterns to print will offer numerous options to tweak the speakers ahead of printing them, or doing modifications afterward.

I mention this only after reading the article and seeing how DALI is using new technology in their magnet designs etc.

To me it seems that all the drivers are connected in noninverted acoustic polarity, but the speaker as a whole was conected in inverted polarity during the measurement.
I suggest that the step response should på turned upside down to paint the real picture.
Anyways this is impressive time domain behavior, I do not recall any speaker matching this.
In combination with the frequency response, the impedance and phase, this could prove to be a very neutral reproducer.
Wonder what their top of the line Epicon can do.
