Børresen Acoustics 05 SSE – the Interview

$

The state-of-the-art Børresen Acoustics 05 speakers and their cables have meanwhile become perfectly acclimatized in my listening room: The system plays even more beguilingly than when I wrote the review. But more interesting than any kind of effusiveness may be the reasons for so much euphony, and Michael Børresen gives them in the following interview.

Just as a reminder: Roland Dietl and I conducted the interview on the day when Lars Kristensen and Michael Børresen had set up the 05 SSEs very close to the side walls of my listening room, as is usual for them, and precisely aligned them with the listening position. This positioning had both bewildered and fascinated me, which is why it came up again and again in our conversations. Roland Dietl hadn’t heard the speakers at that time, but has made up for this later. He experienced them in the set-up described in the review, which allows two people to enjoy the immense capabilities of the 05 SSE, and was just as enthusiastic as I was. The Børresens once again confront me with a question of conscience: Should I enjoy them as long as possible, or should I rather quickly return to my own speakers before I get used to the 05 SSEs, which will make the separation all the more painful?

Let me say a few words about the recording situation during the interview: Lars Kristensen actually wanted to leave the work to his colleague and made himself comfortable on the sofa, while Michael Børresen, Roland Dietl and I grouped ourselves around the dining table and the small Nagra dictaphone. In between, Lars Kristensen, however, couldn't resist making one or two remarks - unfortunately, they weren't recorded acoustically quite adequately. Furthermore, passing trains and my wife, respectively her camera, are to be heard. She also used it to take the pictures of the various drivers, which were not yet available in the photo studio during the photo session of the speakers. You can very much look forward to hearing impressions that not only talk about B&O, but also about the Mosad and F16s.

01The first issue was - as mentioned - the positioning of the speakers, which was very unusual at the time:

02Since, according to Michael Børresen, this set-up can only work if the transducers reproduce music almost completely free of interference - or as he calls it: noise - the special diaphragms of the drivers manufactured in Aalborg were our next topic:

03Even more important than the sandwich material of the diaphragms is, according to the developer, their completely ironless magnet system:

04Once again, this is about the positioning and the interaction of the speakers with the room:

05After Roland Dietl had completed our round, Michael Børresen once again explained to him in more depth the advantages of his ironless drivers and the copper and silver rings between the four neodymium rings:
{mp3}22-01-07_borresen/05-The-patended-motor-again{/mp3}

06Then I wanted to know from Michael Børresen whether or not an extremely exact matching of a pair is the reason why there is no acoustic hole in the middle even between very distant speakers:

07Not only the cone drivers are in-house developments, the ribbon tweeter is manufactured in Aalborg as well:

08The current ribbon tweeter is by no means Michael Børresen's first engagement with the subject, as a brief look at his hi-fi vita shows:

09An almost massless ribbon and an extra mass loaded bass/midrange: How does that go together in terms of velocity? The developer has an answer here, too, of course:

10The very special crossover, which for once is not a Michael Børresen development, plays a large part in the incredibly harmonious and homogeneous performance of the 05 SSEs. Sometimes it’s also helpful to be familiar with hi-fi history:

11Of course, the special circuitry of the crossover is not realised with the well-known audiophile components. Michael Børresen has quite a firm opinion on this:

12At the beginning of the review of the 05 SSEs, I noted that when I visited Aalborg, it was its design that made me arrange a review right away. Now we have come full circle, and Michael Børresen concludes on the subject of design:
