He's right about the capacitors. They form a network that decreases impedance with frequency, with zero being the theoretical minimum impedance. Not kosher at all.
Well technically if I don’t see a reason to do something I don’t do it.......first law of laziness!
Believe me everything I do gets researched in depth, implemented carefully, then stress tested before becoming part of the system. Just because I can’t spot another’s mistakes doesn’t automatically mean I’m making them. Again with the blanket statements.

It's called "learning" Bob, apparently 🙄
That reminds me, did you ever get round to that soldering job?

I'm not talking a belief system ... I'm talking science and physics the way things actually work in the real world.
You want to talk a belief system --bordering on a religion-- go talk to the "Golden Ears" who claim that listening is good enough and spend ludicrous amounts of money tuning their systems with wire, cap swapping, changing OpAmps, replacing output transistors and so on, without any hint of real electronics knowledge among them. These guys will decry the very science that gave them the products they so happily tamper with.
True it doesn't mean you are making those mistakes ... But it DOES mean that you see no reason not to do those things and are likely to have terrible outcomes with no idea why.
I've shown you one mistake you failed to catch ... There are tens of thousands more. If you actually understand electronics you can avoid most of them.
I think that crossover is a mistaken attempt to make a second order crossover with baffle step correction.
You really have to look at a design from all angles. All unintended consequences will be realized in an electronic design.
L1 and C3 are in parallel and will resonate at some frequency. As a parallel resonant circuit they will pass the minimum current at their resonant frequency, forming a band STOP filter. In fact you can see the resonant frequency on the impedance chart at about 2700hz.
If C1 was in series, your woofer would be outputting only very distorted treble, since a capacitor is most conductive at higher frequencies.

Nah, house is a mess finishing up the cabinet work......March is the start date for the new wall of sound project.(stereo stuff is all packed up till then)
Being on here all the time doesn’t help me much! But learning is impotent!
If you would spend less time trying to make me "wrong" and just a bit more time focusing on the actual topic of the thread, we might... well, gees I don't know... have a real conversation...
Sorry thought that was tweeter! Wasn’t paying attention (should practice what I preach eh!)
Yes, I wonder if Douglas has learned anything new or impotant about Faraday cages recently?
Have you learned anything about RF re-radiation?
Like I said... once you capture a signal you gotta give it some place to go. Ground is usually a pretty good idea.
i.e. there is a reason why all that shielding in EM sensitive devices is grounded.
