Being an old fart raised on honking sized three way speakers blasting Led Zepplin, I held out changing my speakers for - lets just say a decade or two. I eventually had to switch over to a sub/monitor setup because basically, three ways were too big and bulking. And in truth, the technology of speakers really has passed them by.
I did try it a number of times to setup a subwoofer speaker setup. And failed over and over again. Sounded like crap!
However I was making the same classical mistake ALL us, lets just say "vintage" ears make. I tried making my subwoofer the "woofer"of a three way speaker. Ahhhh, it isn't engineered that way!
Stop trying to use your sub as a WOOFER. Use it as a SUBWOOFER.
Long LONG story short. I ended up with a pair of Zaph Audio SR71 speakers that go cleanly down to around 50Hz. All the subwoofer does is fill in below 50hz and gently bolster up the bottom end. NO MORE NO LESS. A subwoofer should almost not be heard or noticed in a system. But it should be noticed if it's off or on.
Your problem is learning HOW to setup a sub. Try posting over in the speaker forum and learn how to "tune" your subwoofer properly.
Also some tips I've learned over the years.
Get a good plate amp, like a Kreager from Madisound. You don't need a big ass sub box.
Stop trying to get your monitors to go down to 30Hz - they NEVER will. That's what the sub is for.

Your way works but it can be done with a higher crossover if it's custom designed for it using a computer with good soft ware. I've seen it done. My own system crosses an 18 " woofer passively at 85 HZ and works beautifully. But I'd like to down size so I can move the boxes by my self.
4th order xovers are exactly what I mean by squishing the life out of a speaker.
And once you start mixing crossover orders - now you get into phase shifting, and I don't mean that really cool Star Trek stuff. Slope and impedance matchings that even a seasoned DIYer would have trouble with.
Those xover calculator programs are just basic formula programs. Not an answer to how to really do it. And you will need some testing equipment to boot.
Here is a link to how it's done.
GO with a nice monitor and sub.

Done correctly a 4th order Linkwitz/Reilly crossover is quite dynamic and does not take the life out of a speaker even if used foe a sub woofer. A 4th order LR xover is probably not electrically 4th order. You want it to be acoustically 4th order and that is often only 3rd order or even 2nd order electrically.
