Trying to understand why my speaker don't have basses

Good work! Real progress being made.

Yes and this couldn't be done without you.
It's seems to me that the first response curve (overall) is not bad at all ?

I asked about a active crossover because it can be a fast way to find what works well, even if you use a passive crossover in the end.

I know Foobar2000 have a plugin with a bandpass filter. Maybe I can use it ?

I will send you a PM so that you can email to me your HOLM files. I can dig into them here.

Thanks a lot !
I've send them to you.

Regards,

Christophe.
