AsciLab speakers are about to launch

[kemmler3D]

I think there is value. There is a sensible place to stop when designing a passive crossover, and the manufacturer absolutely should do a great job (as they are here), but that doesn't mean it's optimal if price and complexity weren't a factor. DSP can add a final polish, or subtle alternative tunings for different use cases. If a manufacturer has quality data, and the technical knowledge (again, they have that here) it doesn't look like much work to produce them. My passive speakers have convolution files from the manufacturer that improve group delay and something to in the crossover region, the changes are very subtle though.

This shows why using the generated EQ settings from the review isn't worthwhile, though. If you have your individual speaker's correction curve on hand, great, use it.

If you have a curve that corrects a different speaker from the same run, and that curve may lie mostly or entirely within manufacturing tolerances, it's pretty dubious.

Are custom-made shoes more comfortable? Sure. Will you be more comfortable wearing someone else's custom made shoes that happen to be your size? Doubtful.

I ordered the C6B from Audiophonics in june.

The estimated shipping date has been delayed by 1 month from the beginning of july to the beginning of august. I wonder if I would receive the speakers faster when I order directly from Ascilab?

I received my Fedex invoice for Duty on my C6B speakers: $111.50 USD
Speakers Shipped 6/12/2025
Received 6/13/2025
Duty invoice arrived 7/1/2025

Recently there were a lot of orders So currently we don’t have any stock. AP is the closest schedule for now.

Are you sure that's for you to pay? Post #1441 here showed the same, but turned out it was and Activity Record, not an invoice, and there was no additional monies due.

I just received an invoice also, even same amount.

AP and we try to keep very similar price range.
The price buying from us include shipping cost will be very similar with AP's price.
I don't know how you calculated 460 euro less price.
Anyway, Thanks for having interesting our A6B. We've been very looking forward to sell this model worldwidely.

Do you have an idea when the C6B will be back in stock? And will the price stay the same? Thanks

We expect C6B will be in stock at August at least. We’ll keep the price as possible. There can be some of variation by location(dealer).

 

[Kayshot]

A6B is available for pre-order now, for those interested. $3,300 USD.

 

[Pritaudio]

Are ascilab certain about the product timeline for unreleased models.
Will they cater to demand given suitable desired specification.
I would be interested in 8 inch passive models or even 5 inch passives.
It seems the only 5 inch in their current scheduled product timeline is the c5c active speakers which has no recent discussions.
And the non hypex active models would be even less wellknown.

A6B is available for pre-order now, for those interested. $3,300 USD.

And they raised the price from 2950usd.
No discount for asr members? =)

I counted $200 for shipping so more like $3150 > $3300, they did always clarity fast shipping from south Korea was extra.

Does anyone know what distance from the front wall AsciLab recommends for the A6B?
Can it be very close without dramatic SBIR issues?

Keeping speakers close to the front wall mitigates some of the associated SBIR, while pulling them out exacerbates SBIR. This is true regardless of speaker, generally, for conventional monopole designs.

Thanks. I wasn't sure how much difference side-firing drivers ( and rear ones, for the other 6B series) made.

SBIR's a physical problem to do with pathlengths between you, the speakers and boundaries, and wavelengths around 100Hz-400hz, roughly. It can be calculated in advance, if you cared to spend the time.

Dipoles (like panel speakers and open baffle designs) would require somewhat different thinking because the front and back fire strongly while the sides show broad cancellations.

The side-firing and rear PRs work like a monopole with the front woofer. You can see it in the measurements provided.

Thanks for all the info. One day I’ll learn to read these polar plots- I thought that this showed plenty of output to the rear at 200-500Hz (right in the zone you mention), but I don’t know what the practical implications of -5 to -7 dB might be-I’ll do some more reading!
Thanks again.

And dipole rear reflection doesn’t follow 1/4 wavelength cancellation rule. It needs different math.

Is there any information on whether the active/cardioid models' XLR input is digital (AES), analog, or both?
I've not been able to find any indication, so perhaps it is not decided yet. That is an acceptable answer as well.

Both.
