Great review or ownership experience !
So I understand the above observations are made with the Sonido Driver having the wizzer cone installed.

........
They provide excellent detail yet maintain smoothness and more balance in frequency response than all the others I’ve tried.
After all, there is some truth in what's ZM writing all these years about Sonido

I'm spoiled with quality of best FR and ER drivers of Yore, best ones all members of broad Klangfilm family, and Sonido are the same as best ones, just made today with modern improvements ( glues much better nowadays)
Again, I'm nothing more than satisfied customer, also having a pleasure to visit Sonido workshop eons ago ....... besides exchanged correspondence in all these years
Dayum, I might have to save up for the 'contrarian' oval one.
Also, I've been thinking about those whizzers. Looking at a cross-section, it occurred to me that the glue-line where it connects to the rest of the cone creates a sort-of pivot point, and the overhanging mass of the whizzer may counterbalance the bobbin and voice coil, reducing the amount of work that the spider has to do in reducing vibrations that aren't perfectly aligned with the desired axis of cone travel. It's interesting how the pioneers came up with simple solutions that are still hard to beat 100 years later.

I noticed that some people are overly preoccupied with the fact that Sonido has whizzers.
My opinion: they are often the necessary evils (just like crossovers, if you want to make such a comparison).
Some fullrange drivers manage to do without them, some don't.
But that does not mean that by default all whizzers are bad and make the loudspeaker sound bad (and vice versa).
Sonido uses whizzers and sounds good. Some other loudspeakers don't use whizzers but that does not automatically mean that they sound better.
My opinion: I'd rather have a fullrange with a whizzer, than a wide-ranger without it + a supertweeter. So, we agree to disagree 😀

whizzer issue is not an issue with Sonidos
speaking about that in context of any speaker, without actually hearing it first, is just ......... nonsense

I also, been thinking about those whizzers, maybe some fatigue but not.
You mean remarking that some people have different listening environments, different systems, different preferences and different requirements to yourself is nonsense?whizzer issue is not an issue with Sonidos

Dry humour aside, in case of any misunderstanding -nobody seems to have suggested they are 'an issue' in design or technical terms with these units. It was simply pointed out that people have different tastes, so it's a perfectly reasonable thing for a prospective buyer to ask. As noted, based on the published LspLab measurements of SRR-200, I'd probably prefer it as-is, with the whizzer cone in place too. But not everybody is obliged to share our requirements.
Eventually I cut out all whizzer cone and I satisfied with it.
But mine is smaller swr145a.
My impression about MAOP10 sounds more clear and quiet with heavy bass.
Rings of ripples of sound spreads clear.
Sonido sounds more lively,especially percussion sounds nice and vocal has more guts.

I said: "speaking about that in context of any speaker, without actually hearing it first, is just ......... nonsense"
though, I'm staying good that "whizzer issue is not an issue with Sonidos", under condition that amplification is not having own issues; but - then, if amp is harsh, one needs speaker lacking highs

So yesterday, my Stereonet Hifi reviewer friend and myself were listening to the system below, ( using the amps at the back), it’s a few $$ in any currency!
But we came back to my place and played my 250 FCs in my untreated room, we both preferred the SONIDOs!,
My speakers are “ faster”, and the bass has more detail.
We also played with the control knob on the power supply…
So my boxes are folded Voigt Pipes, so should play best on number 2, which seems about right.
We both agreed that position 0 made them sound a bit sleepy, and position 3 was a bit in your face if you were tired. Position 1 could be a good choice if you are tired!
I’m really happy with my drivers, they probably be my last speaker purchase!!

Agree JD- My SWR 960 FC’s in Sonido's ML-TL cabinet sound simply amazing. They do everything so well. Setting 2 sounds the best in my box and these will be here to stay for a long time. I can see myself trying these drivers in some different boxes (OB, smaller ML-TL, BR) just for fun down the road.
Initially, the speakers sounded a bit bright and fatiguing on certain hi mid/ hi’s even after 100 or so hours. Decided to change my speaker cables to Duelund 10Ga tinned copper, my internal cabinet wiring to Duelund 12Ga TC, upgraded my USB and IC’s to Veritas Top of the line cables along with additional break-in hours on the drivers/transformer made all the difference. I have not heard anything so quiet, revealing, dynamic and incredibly realistic with zero fatigue. So happy with my Sonido choice!

Hi Steinz!
Nice looking cabinets! Wood veneer over Mdf?
Do yo have some sort of stuffing inside the cabinets, if, so, where?
Thanks 😀

Thanks 😊 for the inside photo!
Your boxes look a bit different inside to mine, but you are obviously enjoying them!
Please tell me about your Dueland internal wire.
I’m just using Canare 4s11 for internal wires..

Not sure if that is a rhetorical question or not?…1 set of drivers
not rhetorical at all
I'm just saying that you're DIYer ....... for that money you can have another pair of Sonidos and DIY cables/wires, without any sacrifice in sound
I'm not belittling anyone's work nor product nor questioning prices ....... just saying that - as DIYer, you must strive to know better
though, if money is no object for you, ignore what I said........

It would be interesting to measure T/S paramenters of that Sonido, when in setting 2. No doubt, FC has the advantage of being able to dial-in the preferred setting. So it's not the goal to chase "absolute best" sound, just the one that pleases you at certain moments with certain music.
Why would I be interested: On my part, lately I was playing with variable impedance amplifier, and it was convenient to be able to adjust the best speaker-box-amp relationship. While I presume that most have the amps with a fixed output impedance (low or high, it's up to you), a field-coil gives a bit of "taste control"...
