Sixmoon’s visit to Børresen Acoustics
Srajan Ebaen of Sixmoons.com has just published a very interesting article on his recent visit to Borresen Acoustics and the innovative new technologies used in Borresen loudspeakers. This is excellent reading for current Borresen speaker owners.

Borresen is one of the few loudspeaker manufacturers to design and build drivers in house. I was not previously aware of the use of perforated HDF discs which are claimed to create a pressure environment bigger than the cabinet and also mean [for the Borresen 02 and upward] that drivers sharing the same port don’t see each other.

And then there’s the esoteric stuff – dither tech which designer Michael Borresen is said to have based on an approach borrowed from marine sonar. The injection of Schuman resonance and harmonics to combat a widely known problem of cabling acting as antennas. All cables can act like antennas, both to transmit and receive and this problem has gotten significantly worse in recent times with popularity of WiFi for streaming, not to mention the proliferation of cellular and other wireless technologies used in the modern home. Accordingly, dither tech is also incorporated as filtering in some products of the Ansuz Acoustics product range.

At higher SPL the behavior of the ported alignment is said to shift to more of a sealed box to improve control and power handling.
Thanks for the link kiwi. Srajan Ebaen of Sixmoons.com writes about a great deal of new technology being used in the Borresen line. I already know from using some of the Ansuz products Borresen knows a lot about A/C power conditioning/distribution and resonance control. Look forward to hearing the speakers one day. Hopefully Borresen Acoustics will be successful in the U.S.
