Indeed, and that's a good point. We can see that the Fidelia model from the same designer stand out in this respect. Check attached file

It's cleaner downward though, I guess it's a speaker that you want to place fairly high up (or upside down haha)It ties in the horizontal plane, vertically not so much

@staticV3: can you explain the cause why the Cadentia 3 reaches incredibly good 8.92 with perfect (reaching 14 Hz) subwoofer(s) and eq
only tied by the small Genelec 8030C (8.97) or the Genelec 8331 (8.93),
but the Blade 2 Meta reaches only 8.58?
Here's the paper:@staticV3: can you explain the cause why the Cadentia 3 reaches incredibly good 8.92 with perfect (reaching 14 Hz) subwoofer(s) and eq

Keep in mind that the Cadentia and Kef Blade 2 are passive speakers and the Genelec are active monitors.
Here is a link to a predefined filter that allows you to consistently compare several models within the same category :

Here's the paper:

I don't understand enough about multiple regression models to give a confident answer, but it's all in the papers if you're so inclined.
I'd hazard a guess that the Blade's dip at 300Hz may be the culprit:

What I can tell you with confidence though is that it is ill-advised (even according to the authors) to read much in to the preference scores.
A 1.0 difference in preference score does not say much and differences smaller than that are basically meaningless.
Keep in mind as well that the preference score only describes frequency response and no other aspect of loudspeaker performance.
It is feasible for a speaker to get a perfect preference score, but only at 50dB SPL and in practice that speaker just breaks apart at higher SPLs, resulting in an awful listening experience.

But normally imho the fact, if a speaker is active or passive should not have to do anything with this special quality of a speaker! Or?
I agree with you on that point. But for the sake of consistency, I would tend to compare passive speakers with each other. I'm not knowledgeable enough to explain the differences in Spinorama scores, but I imagine we first need to determine the underlying cause of each score.
In this example.
For "The Pitt & Giblin Superwax Mini" speakers we observe that their excellent score is based on only 4 fundamental graphs
Measurements for speaker Pitt & Giblin Superwax Mini
www.spinorama.org
Tonality (Preference) Score is 7.64 and would be 8.66 with a perfect subwoofer.
Price: 4200
Tonality: 7.6
Bass extension: 24 Hz
Flatness: ±1.2 dB
Wow, very impressive build and front baffle.
Why didn’t you use the same sort of speaker for the woofer like the midrange? Or a purifi mid and woofer?
But I filtered this kind of measurements out before comparing:
Pitt & Giblin:
So, as you say with passive / active comparisons: Apples with apples!
- Quality of the measurement data is low.
My bad just saw it is an active speaker
So here's a double filter with occurrences by score / speaker type and measurement quality

Thank you very much!Thank you very much!
I still haven't forgotten about the kind of centre channel that you are after... but I simply have too much to do in the pipeline! Thanks for your patience and appreciation.
Erin is MiA at the moment, he hasn't posted anything for a while, I hope he's doing fine.This looks great! As a current owner of a 3-way DIY SB Acoustics speaker I look forward to this one.
My speakers only sit 1 ft from the wall behind them, I wonder if this design will work for me?
@Audiofirstdesigns_Harry Will you get one of these to Erin or Amirm? if so, any time line?
He posted today, he got a promotion at his Job and has been busy. He posted today on his Patreon (Dynaudio bookshelf data)Erin is MiA at the moment, he hasn't posted anything for a while, I hope he's doing fine.
FYI, Audio First Designs has collaborated with @pierre and the full set of data is available here:Can you please post vertical directivity polars as well?
Yes I am sending a pair of assembled kit verson to Erin, he's been looking forward to reviewing them since many month ago, haha!This looks great! As a current owner of a 3-way DIY SB Acoustics speaker I look forward to this one.

Oh noooo you dont suppose to see that page at this moment, let me change the setting... thanks for letting me know!FYI: Looks like the first run in kit form is sold out. I did get a message from Harry Yeung yesterday that there will be another batch in kit form in January. The Candentia 3 page now shows pricing for the assembled version at a cost of £4780 / Pair (£3983.30 price excluding UK VAT).
