Usually in the design of the motor, for lower distortion and better IR. FR is similar but IR is not. CSD and HD will also different. But there is something more about it.
I can listen one file blind (D or E) once and with certainty can tell which file it is. They are so different.
Even tho the FR is almost exact copy, I found E has too much midrange (in vocal region) and something not right with HF. May be we need to see detailed impedance variation (in relation with phase).
Ooops, my mistake. I thought you were comparing D to E.... There are too much differences there between E and A 😉

I chose B as runner up followed very closely by D. I only listened to the first clip though...
You forget that 10F is made from fibreglass 😉 What for a strong motor if the cone is deflected.
It is still there. Of course, all driver components (motor, spider, cone, etc) must work together to get the final performance.
I believe that B is among the best technically. Nothing wrong with it. But people like spice in their food... For me, B is too paperish 😀
B is close in tone with Vifa TC9 (which is very flat). B sounds very natural even tho the top end is not flat. This is because the response is tilted down.
With cheap drivers like this there are too many trade-offs. Even more when you have to take everything as is, instead of correcting the problem with crossover...
That's why, when you are using better drivers, the only thing that matter most is the intrinsic non-linear distortion of the driver.
Jay,
Not clear to me which driver you picked. Sound like you have hedged your bets on several drivers with the way your write. Not clear at all - sounds like you picked B but thought it was because it was mystery driver which you assume to be TC9FD? Or did you pick A?

Thanks xrk,
I enjoyed this comparison immensely. My ears are getting old, but I was able to narrow down to E and A and gave it to A because I thought that the details were clear and a bit laid back. A and E, I found very close, and easy to listen to. I do not see how A could be categorized as fatiguing????
Just my thoughts, great job🙂

You are welcome. Glad you enjoyed it!
A did extremely well and I was impressed by its strong showing vs some much higher price point drivers. At $23 and with a Nd motor and extremely open venting on the spider with a paper thin aluminum cone - it produced some very nice results and beat out another well regarded aluminum cone driver.
I think if you look at the response curve, A was unusual in its shape of having a a large 5 to 10dB bump from 2khz to 3khz. That feature may be hard on our ears if we hear it. OTOH, having mild 2-3dB bump in the 2.5kHz range can often make a good driver "Great" as it allows imaging and soundstage to lock in and become very 3 dimensional. I think Wesayso's towers benefitted from just a mild EQ boost there which made all the difference in the world. Perhaps that was the magic behind this driver? It is the only driver with a zinger of a 20kHz resonance that shows up in the impulse response. This will make everything have exaggerated shimmer or air.

so for B. Scott, I liked the $12 AHE and for N. Jones, a $23 Dayton driver - put them in parallel 😀 - - -many thanks for setting up such a comparison. Is the AHE listed at Ebay?

I voted for E. But I have mentioned all the details, my perception of each file (so the vote is not important). Which file I voted is just a matter of... I don't know. My speakers are better than all of those so what should I pick I really didn't know. My speaker has the strength of each of the drivers, not just one.
At the end I have to vote for E as it is objectively the best driver, like I said from the beginning. A driver that i will pick if I can have one of them for free 😀 Of course, I would not use it for full range duty.
But if I have to pay, I think I will pick TC9, and use it for full range duty 😉 If it can be made small enough (low Vas), may be I will use them for birthday present 😀
BTW, I didn't pick drivers based on assumption. I picked based on what i hear. So when I said I picked ScanSpeak, it really meant I picked E, whatever driver it turn out to be. If it is AHE, I will buy a lot 😀

xrk971 did some good hints at post 190. Here is P830986 with a 50dB vertical scale from datasheet think easyer to eye than the 130dB scale at plot post 190. Things is going on there and thinking resonance at 20kHz probably extend even higher in HF area the plot is simply just cut off there. The alias for a DAC running 44,1kHz is sitting at 22kHz and nomal filtered out but having a speaker driver that is so boosted there could be annoying and ruin the DAC filters effect some. That said how we perceive audio to be fatiguing how sensitive we is to wiggled responses and if nasty digital domain alias disturb our hearing even we tested to our hearing only goes to 16kHz is probably different person to person.

Don't get me wrong, there were a lot of things about A and G that I really liked, and on my first few listens I was sure that it would come down to one of those two. I still think they are the most dynamic of the bunch. But the more I listened across a few different systems, the more I became drawn to the smoother tones of E which, while not as dynamic as G and A, nevertheless performed well across all three musical styles (at least to my ears). So while I enjoyed A and G, E is the one that I found most listenable in the longer run. 😀
Hmm, seems I have a tendency for hardware😱) Picked A but was thinking of G also. G went away because of a weird break up in Nora Jones voice. Between D and E, I couldn't distinguish any difference. The others I didn't bother with….
Great work done xrk!!!
Great work done xrk!!!
Well, I think there is going to be a bump in sales of a Peerless aluminum cone Nd motor driver in coming months🙂 For $23, I think it may be a no brainer for many to try.
As an aluminum cone driver, I think it is not fatiguing as one would expect. I have several times (as of now) listened for hours and I don't have a need to turn it off. Probably the most musical

Hmmm... The txt file you posted earlier says you voted for B thinking that it was a TC9FD mystery driver. But you rank A as number 1. But if you say you voted for E that must have been your vote.
