Hello.
For full-range speakers, could you please tell me how to determine "fL / LFbleak pt" for "ESL_line_sectioned_DIY"?
For hybrid speakers, you can probably consider the woofer and slope, but what do you consider for full-range speakers?
If you make it too low, the output sound pressure will be reduced.
Thank you in advance.

You are correct that if fL is set lower than necessary you are just throwing away available SPL.
For hybrid speakers, it is recommended to set fL equal to or 10-15% higher than the desired crossover frequency.

For full range speakers, the lower frequency limit of your ESL is set by the diaphragm resonance frequency. It is desirable to damp this resonance with acoustic resistance or electrical EQ to a suitable Q value in the range of Q=1.5 to 3. In general, you will find that setting fL equal to 1.5 to 2.0 times the diaphragm resonance frequency provides the best compromise of SPL output and smoothness of response. You can use v4 of the Segmented ESL Design Spreadsheet to set diaphragm resonance frequency and then evaluate different choices for Q and fL for the desired LF behavior.

Thank you for your comment, bolserst.
It's very helpful that you provided a rough target for "fL / LFbleak pt".
This is my first time making a wire segment type ESL.
I completed it once, but there were some things that bothered me, so I'm currently working on improving it.
It will take a few more months, but I'll report back when it's finished.
