Help me with the name of a Dutch speakers company.

I read about them years ago but can't remember the name or where I read it. Their design was unusual, they were a kind of controlled resonance speakers with mathematically calculated labyrinth-like chambers in the cabinets. I don't think they were ever imported to the US but can't be sure. I think, they were based in Amsterdam.
Audiovector is Danish not Dutch.
Yeah, I heard of Boenicke.
Not Kharma, though they may do it too, I don't know.
