Speaker crossover capacitor & inductors values: schematic & implementation?

Ah yes, the last line of that post. OP was only guessing, yes.. otherwise the post on the whole would be a contradiction. <shrug>

So you've been doing some reading but maybe not enough thinking. ESR means nothing if there are resistors in series with the caps! High freq means nothing in the woofer circuit. And if you have ripple current there, you're screwed anyway.

LOL. Absolutely. I am often pinged for not thinking! But at least I do read. Smack me if I start believing stupid meme graphics. 😏

I also read that its function is to protect the tweeter from extraneous HF out of the range of human hearing. As its effect is supersonic an air coil isn't necessary. In particular, the ferrite inductor could be necessary if the titanium dome tweeter exhibits a nasty HF resonant peak.

Bo Dacious, I'd advise care when renewing this inductor. It's narrowband effect means that compared to other components you'll want to tune it, ie adjust it to the needed frequency, otherwise it will be ineffective.

This is the conclusion that I have been reaching. That is it there to manage something in the ultra-high frequency range, that it probably (but I can't say for certain) doesn't have any affect on audible frequencies, and it would be a PITA to try to improve or replace it.

Indeed.
Guessing. Questioning. Postulating. If I actually knew anything, (besides being dangerous) I wouldn't need to post the question to try to solicit community knowledge and consensus.

Breakup peaks usually go away if you listen a little off-axis, which arguably is a good idea in any case.. for the same reason. The 0 degree listening angle is not representative of the total output, and you want your direct sound to resemble the room contribution. Some go so far as turning the speakers away from the walls and crossing them in front of the listening position.

Some do this based on the level of treble it gives, but I do it for geometric reasons and equalise the treble to suit.
