Tells me English is a second language to the writer, and they estimate larger value resistors attenuate the level more.

I will translate this datasheet, ok? Just give me a few minutes.

Take all the time you want, turd polishing is not a useful pursuit :^).

What do you mean? I meant datasheet. Not that other word.

Here it is. Sorry to have posted with foreign words at first.
What do these numbers tell you now?

Posting here a variation of the latest circuit. Moved R1 from paralel position to series (according to piezo datasheet, not frugal article). Shouldn't bear no audible difference, should it?

That change would certainly measure quite differently, whether you can hear the change is another question entirely .

Ok but theoretically, which one is correct. Parallel or series?
You said that without a resistor in series, it would never been seen as a driver, and it would crossover at 2000 Hz.
Does this move of the resistor changes anything and accomplishes what it is supposed to accomplish?

1) Both are different approaches, each is "correct", but will sound and measure differently.
2) You are dealing with drivers that probably have little in common with the "frequency curve response" you posted in #25, with an unknown impedance, I can't help you decide anything without knowing both. Measure (or listen) and decide which accomplishes what it is supposed to accomplish better for you.

Have fun, good luck!

Ok, thanks. I will do the paralel one.
