Are they the same size enclosure?
No, F6B box is deeper:
F6B (HxWxD) 15.7 "x 8" x 10.4"
F6BS: (HxWxD) 14.5" x 8" x 6"

...I don't like the website layout.
Website is a typical "modern" design - confusing, with irritating sliding pictures and texts, attacking from all sides.
 
Between the F6B and the F6Bs, I would not be focusing on the additional bass - instead I would look to listening reports of how the difference in the midrange ends up - the thing that "identifies" speakers most, and seperates the great ones from the also rans, is how well they do in the midrange.

The primary difference between the two models is the midrange resonance, with the F6B having a more constrained (in bandwidth terms) resonance at a higher frequency, and the F6Bs having a broader resonance frequency area slightly lower in the frequency range.

Without listening, I have no idea how noticeably these are... but they would be the primary "fingerprint" of these speakers.

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....
 
When is the F6BS over the F6B recommended? Distance from the wall?
My speakers are 5" (12cm) from the wall but my amp has a HPF for the sub.

No, F6B box is deeper:

F6BS: (HxWxD) 14.5" x 8" x 6"

When you want more bass.

F6Bs has quite a shallow profile and no rear port so it seems very well suited to being close to a wall. Having vesa mounting as well makes it potentially a good choice for wall mounting such as LCR or rear use. It would be interesting to compare these to KEF Q4 meta or Arendal 1961 as an on-wall speaker.

If you're using a sub the F6Bs and F6B are probably fairly equal but otherwise I will probably take the F6B as it has more bass.

Thanks! I'm really considering them along with a sub.

Would it be a nit if I suggested to aSciLab to re-evaluate their current/confusing model-numbering convention?:facepalm:
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.

Should I take that answer as a "Most definitely, NYET!"? :facepalm:
Should the thread topic be corrected to a capital "S", in the model#?
I had thought my nit would have been a benefit to aSciLab, as well to the customers who are linguistically-challenged [including self].

Below are the after EQ responses with Maiky's and Pierre's EQ. The main differences are the different corrections at < ~90 Hz and more "flattening" by Maiky at > ~2 kHz, especially > 5 kHz. I personally prefer Maiky's but I think the differences would be very minor.

(I only used Maiky's EQ LW as his 2 sets of EQ are actually very close to each other.)

[Edit] I believe for Pierre's EQ at > ~2 kHz, he prioritized maintaining more straight but downward sloping lines for the early reflections (ER) and sound power (SP) curves than Maiky's.

Very clear, thanks a lot!
 
That price increase is nasty o_O
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.
