AsciLab speakers are about to launch

[somebodyelse]

Probably the same reason we see 80dB SINAD amps in Genelecs: they are simply good enough.
My second guess is that the engineering of such amps focuses more on reliability,heat issues,vibration,etc. ,exotic measurements are for the other models.

That's why they wouldn't (which I agree with), not why they couldn't.

For me they have followed the ‘how to make really fine measuring contemporary loudspeaker handbook’ ,
1, Know exactly what you are aiming for,
2, Acquire the very finest tools .
3, Work incredibly diligently until you achieve the initial goal.
The only slight caveat I haven’t actually heard them, but I am in no doubt they will sound transparent.

Do you or anyone here know the story behind the company?

It is not everyday that we see a company start with a klippel, decently sized production facilities, and production capabilities (we've plenty of speakers in a ware house), the capability to design a complex waveguide and the assorted enclosure. I also assume they have the staff to operate that this scale. This is seriously impressive execution.

To me this looks like audio designers forming their company after having worked elsewhere. I deeply unfamiliar with the Hi-Fi sector in Korea, but it would be nice to know more about @ascilab .

Measures are good, but they aren't everything that make a product, there's consideration for after sales support, reliability, whether the company will exist for another 15 years, and so on an so forth.

We are basically room acoustics consultant over 15 years and quite famous in Korea.

Plenty of recording studio and mixing room, personal listening room and home theater are what we’ve designed and tuned.

Both Hi-Fi and pro audio environment, we’ve designed their room by measurement based way. So through our previous task, we’ve had also lot of experiences about very various of speakers by tuning and measuring.

It helped us to make our philosophy and standard of “what should a good designed speaker be?” And also how to design them.
And we know what happens in our room when we listen speakers. Understanding both loudspeaker and room acoustics really makes a lot of synergy.

This is our background story.

As you know, there aren’t lot of famous speaker brands in Korea to be able to compete in global market.
We hope for us to be that one.

That explains the amazing listening room. (Edit - added new picture to show that awesome ceiling!)

That explains a lot!

Are you still continuing your acoustics consultancy business or is speaker designing/manufacturing your only activity from now on?

We do both of them now and we will.

 

[Salt]

Makes sense, there will be synergies, certainly

 

[Reddoc]

That's why they wouldn't (which I agree with), not why they couldn't.

Yes, I for one would pay for something near state-of-the-art. Good DSP, fully-transparent DAC and Purifi or Nilai amps with SINAD well over 100.
Plus those astounding Purifi low-distortion drivers (including the new tweeter).
Good enough is good enough- to want more is purely fun and does not need defending.

Our room acoustics brand is called Acousticfuser, and although we currently only manufacture and sell in Korea, you can view various installation examples on our Instagram page.

- will there be a wooden finish available?
- is there a chance, that the passive Version also becomes the cardioid function? I don´t need more bass (4 subs as dba) but would like to have cardioid until crossover and already have an apollon purifi amp....

Wood would be nice. Can only speak for Dutch interiors but would be a better fit for most here.

We also consider wood enclosure too, but not in near future. Our enclosure material have lot of advantages than wood.

Passive cardioid has higher odd harmonics in the range that through cardioid hole. Typically midbass range.
We are going to design cardioid speaker only with active DSP.

I like white finishes more and more. Inconspicuous. The material has a nice texture. The light mint green version is cool too.

“Passive cardioid has higher odd harmonics in the range that through cardioid hole. Typically midbass range”

Isn’t this rather dependent upon driver choice and not inherent in passive cardioid design? Would be great to see your data and driver complement which led to such a conclusion. Thanks!

Great work by the way on these new designs, cool stuff

It's related the sound through cardioid hole. Losing sensitivity also can be the reason but I'm saying more about the sound passing through the hole(and absorber).

Thanks … then can you not modify the size/shape/location of the vents to get rid of the harmonics?

We are doing QC for every sample of tweeter. Cause we design low XO, and tweeter voice coil height is very short as 1.3mm, it should be very tightly managed to use good condition ones. By our Klippel KA3 we can sort out the bad ones and good ones. and Also we can manage the tolerance too.

For tweeter, due to its very short voice coil height, it's easy to have asymmetry Bl(x). This makes a lot HD especially H2 around Fs.

As example below, you can see the Bl(x) looks quite asymmetry. By only less than 1mm shift, following the amount of asymmtry, it can make more than 10dB higher distortion, even 20dB for bad ones.

So we check the every sample and correct the voice coil rest position as below.
This not only improve H2, but also H3. More stable, and lower IMD too. you can see the gragh we attached.
Red and Orange line is the current distortion of the tweeter before correction. and the Blue and Navy line is the distortion of corrected one. (edited)

Great design needs great efforts. We are working very hard recently.
Hope for you guys to listen our speakers soon.

 

[Joaquinín]

Navy and Blue line is the current distortion of the tweeter before correction. and the Red and Orange line is the distortion of corrected one.

I don't know if I am reading that graph correctly, but I guess it's the other way round? (red and orange being before correction, dark and medium blue traces after correction).

Thanks. I wrote wrong. Edited.

 

[kharan]

Is there any chance the voice coil position being changed due to components aging or shocks during transportation?
