Just saw mention of this venture in VoiceCoil magazine.
Lots of impressive resumes involved in this collaboration. Main focus is improved transducer design and class D amps from the looks of it. Transducers - Purifi Impressive performance for a 6.5" driver. |

The next AudioXpress will have a report from me about a presentation Bruno and Lars did for the NL AES section. That will have more technical details about the improvements in both the class D and the driver.

Why is long stroke good......large cone displacement causes doppler distortions does it not ?.

I'm glad to see them taking on speakers now. Electronics have been more than good enough for years at this point.
I like the systematic approach to design that they're doing. Focusing on problems that are the most audible in your typical 2-way bookshelf speaker system. I like my big speakers but I can appreciate the effort to get more out of a small box. A controlled directivity design like the Kii or Dutch&Dutch using these improvements will make for even more impressive clean spl for a given size. Very attractive for the typical listening room. |

One would think. It's a type of FM or even IM distortion. There isn't much info about how it's tackled. The Jordan Eikonas are long throw and use "contraflex" cones, little info about that also and only in older papers.

Edit: the reason for interest in small long stroke is of course because of the trend towards more compact speakers with adequate output levels. Jan
