I am interested as well.

[Video] Speaker measurements by Danny Richie

How about Danny sends in some of his speakers so Amir can take some real measurements on the Klippel machine?

Before you measured them, did you have any audible inkling there was a huge dip in the response there?

Same loudspeakers Behringer B2030P with same crossover but with different quality components. The sound difference is very noticeable with my small coaxials.
Okay all of you nay sayers, flat Earthers, etc.

An air coil has for example less distortion at high currents compared to an iron core coil and big MKP capacitor has different ESR value than a small elektrolytic type, this are factors that can be measured and modelled and change the behaviour of the crossover, just the nominal values don't fully electrically describe RLC elements.

Well, weeks ago I improved the crossover of the Q100 and the sound improvement was spectacular, as I said. Bypass the tweeter M.D.L. cap with Miflex KPCU-01 0.02uf 600Vdc and changed the sand Bennic resistor with Mills MRA.
I cam not find a logical / credible explanation for such an impressive sound difference. First the condenser and weeks later the resistor.

I look forward to seeing the Klippel test on them with and without the "upgrade" Nobody else has the balls to send them to Amir for testing.
Confirmation bias , logical and creditable explanation .

That set of speakers has been making the rounds for years. I had them about 5-6 years ago and had to repair multiple soldered connections inside because of the poor workmanship. I don't know if the previous folks who auditioned them were listening to them broken or not.
I did verify (by measuring at the woofer/tweeter terminals) the two crossover networks were yielding the same electrical response. They were pretty close, but not exact. Not close enough that I would consider it a valid A/B comparison.
Those speakers are okay stock. They don't need to be "fixed" by Danny Richie.

No two loudspeakers will measure identically. Danny is full of it and NRD (Jon) is just a shill if you ask me. Danny doesn't even believe in DB/ABX testing.

Audioquest managed to make a demo showing differences in HDMI cables, too.

Richie is unfortunately in the Audioquest lane.
What? How did you listen to them? Suggest using the seek bar in youtube window to jump between the two samples back and forth. Once you do that, there is no audible difference to speak of. Try it on the last clip that is longer.

Actually, now that I look back at the original AC thread, I realize it was nine years ago I repaired these speakers and evaluated them. Time flies.
And btw maty, they're not B2030P speakers. You might want to read the (entire) original thread and the back/forth I had with Danny on the whole concept of the comparison.
I can't believe this tiresome comparison is still a topic of conversation this many years later.

Same Behringer with same modifications but with different quality componentes in the crossover. The sound difference is notorius.
KEF Q100: first I changed the condenser bypass (NOS polystyrene) in a box and compared. With me was the same person who with the previous bypass was not able to appreciate it but now we both hallucinate with the change. I used the best version of Hotel California (Eagles) of the many that I have in all types of formats. And that with just one speaker!
A few weeks later I did the same process with the resistor. A big difference, not so spectacular, but very striking. We both appreciate it.
Probably the big improvement is also due to the fact that the original capacitor and resistor are very bad. But with the cheap NOS polystyrene only I was able to appreciate the difference, much smaller, hence the big surprise, I did not expect that sound.
The expense is minimal and anyone can try to verify it for himself. With a quality recording and high DR.
