Found this on the Shark. Hopefully I can hear them before the RMAF since Tyler will be showing them. I'm going to see Tyler today and will offer to break in the 03's
Børresen Acoustics – Better by design?
Well, the Børresen Acoustics price list may be out but the million dollar question remains – that is, what has Michael Børresen produced this time and how might it be an advance over his amazing design efforts for the Raidho and Scansonic brands?
At first glance there does not seem to be a lot differences between the Børresen Acoustics and Raidho Acoustics designs, but looks can be deceiving.
Looking at the similarities, both brands employ high resolution ribbon tweeters combined with light stiff high speed woofers. Both ranges are ported with an advanced air-flow system designed for optimal energy management and release and thereby permit the use of attractive domestically friendly cabinets of vastly smaller profile than sealed designs. Yes, both even use Ansuz for internal wiring and it’s my understanding the Raidho will continue to use Ansuz cables internally even if they have recently appeared to shun their external use at tradeshows. Finally, pricing is very similar as well with the walnut Raidho D-1.1 retailing for US$29k and the walnut Børresen Model 01 retailing for US$30k.

So what’s different?
The key difference is the drivers and more specifically the driver mechanics. The original Raidho ribbon tweeter was designed 15 years ago and it’s really what kick-started the company. At that time Raidho was not a well-known loudspeaker brand and it wasn’t until 2008 aided by the benefit of increased exposure and positive reviews of the Arya C-1.0 2-way monitor that the world really started to take notice. I remember around the same period auditioning the C-1.0 in a dealer showroom in Singapore. The dealer carried the KEF reference loudspeaker range but after auditioning the C-1.0 I was so completely besotted that I did something I’d never done before – I said I’d buy them even without asking how much they were! The C1’s were a small wonder, quite simply the most revealing speaker of pure musicianship I’d heard. The resolution was tremendous, right across the impressive frequency range and from front to back where the C1 opened deep wide soundstages.
But time marches on and other than a mild revision to the ribbon tweeter with the .1 series the foundation has essentially remained static for 15 years. Nonetheless it’s a testament to its design quality that the tweeter is still widely considered as one of the best in the world today.
Michael Børresen has designed an all new tweeter; one which he feels far surpasses his earlier effort. The new ribbon tweeter has a totally different using an even lighter membrane of revised and improved pattern, a stronger motor system and greater power handling. The speed at which the tweeter is able to track audio signals and the increase in dynamic headroom sees the introduction of tweeter side vents. While the old Raidho tweeter was also vented, it wasn’t as obviously so in the models below the D-5.1. Further an increase in the tweeters frequency response means the cross-over point to the woofer has also been reduced to further enhance integration. And speaking of the woofer it is also all new. Taking on-board market feedback and learnings during his time with Raidho the new 4.5 inch woofer is revolutionary. The new woofer has no iron and less moving weight being one of the lightest and stiffest ever made. The woofer has increased dynamic headroom and improved efficiency. In sum the overall design focus for both drivers has been on reducing dynamic compression, increasing dynamic headroom, optimizing transient response and enhancing micro resolution.
If you are looking for close up photos of the new tweeter and woofer – you won’t find any yet. The reason for this is that the innovative driver designs have been submitted for patent protection.
Michael has also further refined the airflow system. Børresen Acoustics like Raidho before it eschews massive tomb like inert resonance dead cabinets. Instead they incorporate air flow technologies which are the result of speaker cabinet airflow research where the speaker cabinets are influenced by time defined partial air reflex impulses caused by the defined interior architecture and overall shape of the cabinet – a beautifully crafted lute shape with an airflow vent port system in the rear. The air flow design reduces the need for extensive cabinet damping material in favor of system regulated mechanical damping. This the designer believes this has many advantages including reduced cabinet weight and resulting sound that is pure and a better imitation of the sound of natural musical instruments.
Finally, those of you who are presently use cable and accessories from Ansuz Acoustics will really appreciate the sonic improvements afforded by the passive and an active coil technologies used in products like the Mainz8, Ansuz D·TC and 2-series cables. When these products are employed users frequently report how stunned they are when presented with previously unheard natural micro details present in recordings which are they are familiar with. It goes without saying Børresen Audios new loudspeaker range draws heavily upon Ansuz’s most advanced Tesla Coil technologies and mechanical grounding devices as a performance differentiator between it, Raidho and other loudspeaker manufacturers.
So, will they be worth their price tag? As with all things audio I’m sure opinion will be divided. To arrive at any sensible conclusion one needs to hear them and the first public opportunity for that will be at the RMAF show in Denver, Colorado; Oct 5-7.
