AsciLab speakers are about to launch

[AsciLab]

That’s unfortunate. What about trios?

A package for a center channel or an L, C, R configuration is difficult to offer at this moment, but once production stabilizes, it's definitely something that could be added at any time.However, as mentioned earlier, the initial sales will be focused on stereo pairs first.

A kind forum member helped arrange for me to audition some of these speakers. I met the ascilab team in their Seoul space and got to listen to C6C Prototype (Cardioid) speakers and S6B Prototype (Purifi) speakers. I won't bore you with fancy words, but they sounded very very good. I was particularly taken by the C6Cs (to be fair, it was my first time listening to cardioid loudspeakers). The room was well treated as well, which I guess is unsurprising given their background, and it was a treat to get a peek at the Klippel NFS doing its thing.

The price points seem very reasonable as well.

Hats off to the @AsciLab team!

apologies if this has already been asked but is there an EU distributor (not UK)?

For now I don't think so.

Jinsung just sent me the measurements they are extraordinarily good, what exciting times.

There goes any hope for having these speakers for a deal in the US. 25% tariff just announced.

 

[AsciLab]

As far as I understand, under the current reciprocal tariff policy, the changes to the U.S. de minimis rule apply only to China and Hong Kong.
If the policy for South Korea remains unchanged, products valued under $800—excluding shipping costs—should still qualify for duty-free entry into the U.S.
In that case, the F series and the C series (when sold individually) can be purchased without import duties.

Looking ahead, we hope that by the time higher-priced speakers (exceeding $800) are released and sold between Q2 and Q4, the reciprocal tariff policy will be eased.

 

[AsciLab]

I’d like to share some of concept images.
Our new Purifi tweeter waveguide/phase shield is developing.

With phase shield in the waveguide makes the response more linear and boosted UHF sensitivity. We got about 4dB higher sensitivity with this phase shield grill than previous ‘waveguide only‘ version while keeping the directivity constant and smooth.

Here’s the results.

Or sell the expensive speakers single, customer wastes more in shipping but the amount is below the $800?

For under $1.6k price products it can be an option.

 

[JohnnyNG]

I notice Purifi’s acoustic lens/ “Coherer” is gone. Just not needed with your waveguide?

And now a phase shield is back. Looks awesome!

This is too beautiful to sound bad.

Speaking of looks, I must be the only person who prefers the looks of the Purifi woofer surrounds over the looks of the SBA surrounds. I think it's the colour contrast and the size of the surrounds relative to the cone that make them look a bit off to me.

@AsciLab would you consider giving the F6BS speaker wire cutouts to facilitate flush wall mounting?

That'd make it a perfect spiritual successor to the Arendal 1961 Bookshelf: https://arendalsound.com/product/1961-bookshelf/

Like the Arendal 1961 Bookshelf: https://arendalsound.com/product/1961-bookshelf/

F6BS only has Vesa 100 holes. If there is mouting braket there will be enough space for cable.

No one can accuse you ( Ascilab) of not sharing measurements.
Every manufacturer should and it’s a huge shame they do not.

@AsciLab I'm curious to understand the rationale behind the design of a "phase plug" for the SB tweeters and a "phase shield" for the Purifi tweeter.

You can regard Phase plug and shield as same thing. We don't matter how to call them.

They basically make some diffraction that reduce Tweeter-Waveguide diffraction or refine Tweeter radiation pattern in result. And they also make a little of compression to boost top frequency. It improves a lot tweeter sensitivity at top frequency. As same as many of "acoustic problems", It is also about time alignment. If you wonder for me how to design it, we simulate first and do so many trial and error in real measurements.
