Borresen Acoustics Loudspeakers

Congrats on the in-coming Borresen 02 speakers.

Based on the impedance plot for 02 speakers [below] which shows impedance dipping down to around 3 ohms at low frequencies, though with superb phase linearity, you may wish to focus on integrated amplifiers with good current handling capabilities and a robust power supply design.

All three of your options, the CH Precision I1, Dartzeel CTH-8550 mkll and Vitus SIA-030 look at first glance to comply so it really comes down to subjective preference after listening to the various combinations.

For what its’ worth – which isn’t much – based on an audition I had with the SIA-030’s smaller brother the SIA-025 I feel Borresen speakers really shine with high quality Class A amplification. YMMV.

Kiwi thanks for your input, a agree the SIA-030 might be a good choice for the 02s.
If Class A works well with Borresen speakers do you think SET amp like the Aries Cerat Genus 25w would be up to the task to drive them ?
 
IMHO the Aries Cerat Genus is a gorgeous amplifier but 25 Watts is not adequate for the Børresen speakers if music tastes are broad and include rock or orchestral music played at anything approaching live listening levels.
 
Hi guys, i will try to make the effort to purchase the 03s and not have to upgrade speakers anymore, therefore i need to know what kind of integrated amp will be up to the task for this level of speakers.
I'm wondering if the Technical Brain Int would match tonaly and have enough juice.
I don't want the Aavik U-380 because i don't need the internal DAC.
The Momentum Integrated is most likely the best option if budget permits.
 
In this recent interview in Hong Kong Michael Borresen answers a number of questions about his loudspeaker design philosophy.

Questions answered include:


Why it was important to remove iron from drivers?

How low inductance in speakers reduces phase shift in the bass and make it easier for an amplifier to drive speakers

What are the problems with bass ports and how Borresen addresses them?

Why Borresen prefers bass reflex speaker designs over sealed cabinets?

Why Borresens 01 stands are low mass, light and purposely designed to transmit energy to the floor?

Why Borresen completely avoids aluminium materials for loudspeaker cabinets

Here's a rather generic question -- how do Borreson speakers produce great sound with what looks to me rather small cabinet volumes? Other speakers in their price range (not that that's the only relevant marker) have much larger cabinet volumes, right?
 
larger footprints and drivers that have larger diameter drivers to push larger amounts of air should be more efficient and be able to play deeper, right?

I think a lot has to do with taking the iron out of the magnet. Mike explains it pretty good in the video above.

I got out of the video that removing the iron does a few things, but not related to volume of air moved by the driver, which I think of as directly relevant to cabinet volume. He talks about the iron with respect to phase angle, etc.
 
Speed or volume. These days it seems most designers build their floor standers to be coherent and articulate to 80 maybe 60hz expecting the bottom 2 octaves will be handed off to a sub. Thje true 'full range' speakers are too expensive for most of us, how bout that VSR review by TAS?
 
Borresen 03s beeing very expensive i need to look at integrated amp options if i cannot afford CH Precision separates and top of the line Totaldac.
Which of Vitus SIA-030 or CH Precision I1 would be the best match for the 03s ?

The CH Precision I1 would be the safe bet with "proven synergy" partnered with Borresen (and Raidho) speakers. The best way would be for you to audition them both of course if at all possible.

Hi Marcus, the I1 is no problem i know very well the dealer he will lend me his, regarding the Vitus it will be much more complicated to get one on loan.
By the way i did go audition the I1 at my dealers once again just a month ago, great experience!
 
question about the optional colors.
does that include the front baffle? i mean 1 color all around the speaker.

i was just thinking and ended up in claudi bibi velvet dark green
https://www.wilhelminadesigns.com/en/cushion-bibi-velvet-crane-dark-green.html
all black looks too massive to me and serial 2 color is one color too much for my taste. all wood would be beautiful as well if possible.
i think the frontbaffle is wood, but maybe the direction of the fibers is different to the sidewalls.
b3 in bibi-velevet dark green, what do you think?
 
unluckly the link displays the cushion with the two birds,
the color i find cool is the cushion to the bottom left, the one with plane color

That might be a good question to directly ask the factory or your Borresen dealer.


Usually the custom colours are for the cabinet. The front metal faceplate, speaker baffles and surrounds are fixed in a dark gray / light black colour.


With color selection you need to consider what you like, your existing décor and the impact of colour on resale value.


I haven’t personally seen any custom colour Borresen speakers but imagine they’d follow what they did at Raidho. Seen below for example is the D-series Raidho in a custom colour, Lamborghini green.


 
thx kiwi!

ahh, the front faceplate is out of metal. i thought it was wood. that makes it very difficult to match the colors perfectly. and would cost a lot more. and the producer would need to agree to the extra step as well.
however, an all around bibi-velvet dark green b3 is just flashing me there in the middle of the brain.
i do think the shape of the b2 and b3 has the best potential for biggest WAF......and my wife says she doesnt like the look. i think its because the 2 color puzzled her perception.

if you scroll down a little, a b2 in all black

i need to add, i have never seen a borresen-speaker in real....so what do i comment, lol

about resale value, you are right to mention it. well, usually you pay more and get less when you sell it. you can bring things down close to unsellable with your very own individuality, a brown car with orange seats etc:)
 
Florida Audio Expo 2020



Borresen Acoustics together with sister concerns; Ansuz & Aavik Acoustics will be demonstrated by North American distributor; Gated HiFi Distribution at the upcoming Florida Audio Expo.


February 7-9, 2020
Friday and Saturday 10:00 – 6:00
Sunday 10:00- 5:00


Embassy Suites by Hilton
555 N Westshore Blvd, Tampa, FL 33609



The room is 1013 on the 10th floor.


I understand (though I’ve only heard this 2nd hand, so it may not be correct) a similar system to last year will be displayed; Borresen 01 speakers, Aavik U-380 integrated amp/DAC, a Naim CD5XS CDP used as a transport and top of the line Ansuz accessories, including PowerSwitch D-TC Supreme, Mainz8 DTC Supreme etc.


Below is a video by AVShowroom’s of last year’s Florida Audio Expo 2019 system.





And this one also from AVShowroom’s from the RMAF 2019 show.


 
Florida Audio Expo 2020


Here are some photos from the Borresen / Ansuz / Aavik Acoustics room at the Florida Audio Expo 2020.

Lars Kristensen, CEO of the above high end audio brands together with Emil Kristensen have flown in from Denmark especially for the show. Gated HiFi Distribution is represented by Dana Mueller and Amy Wollack.

Confirmed now, on demonstration is a complete Ansuz foundation including the latest PowerSwitch D-TC, Mainz 8 DTC Supreme distributor and the new Ansuz resonator which can be seen sitting on top of several components.

Source is a Naim CDP used as a transport and separate Naim streamer, connected to the latest Aavik U-380 integrated amplifier and DAC. The speakers are Borresen Model 01’s.

The lads from Borresen Acoustics are liking the Embassy Suite rooms, which were originally built as condominiums and offer reasonable acoustic isolation.

Show attendance looks to be good with strong interest in the room from early in the start day.
 
I stopped by yesterday. The room was very full with people. The little Borresens sounded quite nice with lots of dynamics and impact.
