There wasn’t price increase.
We decided to include shipping cost to the price to prevent confusing when purchase.
So the price Amir wrote looks lower than now, but it is actually same.
A smart move in the long run. A lot of people will cringe at a $150 for shipping on a $575 item but will be okay with free shipping on a quality $725 pair of speakers. The idea that they aren't paying for shipping makes people happy.

exhibit number one:
Ok. Shipping price seems quite high but fair enough.

I gotta say: the website is a bit challenging..... I really like the finish options though, to me it sets them apart from most speakers at the price point... The only sub $1000 / PR I like better for looks is the Philharmonic ceramic mini....
Phew, I thought I was the only one that thought that on the website. The finish on the speakers actually looks better in the photos customers have posted, the pictures on the site make the speakers look a little bland. I thought the entire speakers were plastic from the pictures. I had dismissed them based on initial impressions and then when I saw pictures posted here was much more tempted to order.

Website is a typical "modern" design - confusing, with irritating sliding pictures and texts, attacking from all sides.
It is a mix of pictures that seem like they'd be for technical equipment and flashy movement. Bland and flashy is not a common combination.

Would it be a nit if I suggested to aSciLab to re-evaluate their current/confusing model-numbering convention?:facepalm:
I also thought I was the only one who found those confusing.

While it does make sense now and is probably great for internal information and distributors; if I need a decoder ring to figure it out, it still isn't fun for me. As the line expands it is only going to get worse.

I think it doesn't help that the overview page on the speakers doesn't highlight their differences, it requires clicking on each one and and then going back and forth to see.
 
Nice to see them in Europe now.

I’m deciding between these and the Neumann KH80. What would be best for near field listening? I’ll be using them with 2 sealed subs.
 
Is this really night and day compared to Adam T5V?
I would say not if you're not gonna be using them with a sub, because the Adam T5V reaches lower in the bass. You could also use Amir's measurements of the T5V to do an Anechoic EQ on them to make them even better, (you could probably just use Maiky's EQ). If you're gonna pair both with a sub then the Ascilab has lower distortion and a better frequency response, albeit you'd probably have to cross it at 120Hz for the Ascilab, and we've already said you can do an Anechoic EQ on the Adam T5V to make it better than it already is. If you sit fairly close to the Adam T5V and don't listen at loud levels then you may as well stick with the Adam T5V I'd say.
 
How To Speak AsciLAB!

How to Speak AsciLAB :-
S= Signature model, using all Purifi drivers.
A= Purifi Aluminium woofer and ceramic-aluminium tweeter.
C= Ceramic Aluminium woofer and a ceramic-aluminium tweeter
F= Fibre woofer and an aluminium tweeter.
B=Bookshelf
C=Cardioid
The middle number represents the diameter of the main driver in inches.
The final letter denotes the type of enclosure.
BX8C and BX10C are the Sub bass cardioid extension modules.

Why isn't there a single model with a soft dome?
I think that's more important to some people than Purify aluminum or "regular" aluminum twitter.
To be honest, I like the regular version better because it spreads the tweeter beam well at its upper limit, rather than the Purifi phase plug which looks more like a kind of tweeter protection than a real "phase plug". But I didn't see the measurements for the Purifi twitter did anybody measure this version?
I am sceptical about phase plugs because lot of them has no real perpose except to protect twitter and that is about it? Like Elac debut 3.0 has phase plug that doesn't do anything....
But this one is a real deal
Both of them has aluminum twitters but the Elac dispersion is a real mess, like bed imitation of Andrew Jones

Nobody should be concerned with whether a tweeter is a soft or hard dome. What matters is the performance of the speaker as a complete system.

I'm extremely confused by this. You're "skeptical" of phase plugs, because... reasons? But you acknowledge that this one's "a real deal"? What is your actual concern?

I updated my post,read it.
I agree that speaker has to be examine and evaluate as a whole complete unit, but that is me and I now there are people here who won't buy this beautiful speaker for that very reason . Some of them are my friends... and I understand that they are afraid of that "oil can resonance".
On the older aluminum twitters there were really ugly resonance 15 decibel tall spikes above 20,000hz. I know that's probably not audible, but hey, heads were rolling here for less . Just look at the DAC measurements and they numerous filters that deal with intermodulation and Sinad stuff....

They probably didn't hear you at Revel Focal TAD and other companies that offer beryllium domes, not to mention Bowers and Wilkins and they "diamond"snaik oil :facepalm:

Be and Diamond coating makes less break up peaks. They are pushed up and also well damped. But less break up means also more perfect piston excursion by being more rigid diaphragm. That leads to have narrow dispersion at top frequency.

Alu dome usually has break up peak around 27kHz. Of course It can be differed by dome geometry. And before break up, non-rigid mode can make wider dispersion than perfect piston mode.

For silk tweeter, It may look it doesn’t have break up, but it has. Actually a lot. Just it doesn’t show “narrow break up peak” because the silk dome has several low Q break ups in top frequency. Some boosted top band response of silk dome means that. Additionally at top frequency the silk dome moves like ring radiator that makes super narrow and uneven dispersion. It can’t be widen by phase shield.

We wanted to get constant and wide dispersion without break up below 20kHz. That’s why we use Alu dome tweeter.

also i dont know if silk dome here is meant as soft dome, but usually theres a coating and that coating do try up (but in ~10+ years i think someone said in dynaudio)
 
But the graph shows more bass for the FB6?
Oops. I read the post backward. :) Sorry about that.

The advantage of the F6Bs is that it is cheaper and doesn't break up in bass when pushed. There is no issue about being close or away from wall as in either case, you need EQ for bass region although less modes are excited by F6Bs than F6B due to lower bass output.
 
This "s" is a problem because it looks like a pair of F6B versus a single F6B. :cool:
@AsciLab As you can see many people have difficulties with the names. I really think you should reconsider this system with letters. Some good suggestions were made already..
