What are you trying to say?
Did he arbitrarily place that value inductor in series or did he calculate its value and then experiment with different values to arrive at his final documented design?

This is exactly what I thought was what I would have to do.

What are you looking to do with the lower of the two mid-woofers and why?
Seems to me that the sub should handle that portion of the work but I am way open to your thoughts.
I am still going to build a center with the four ND64-4's and a tweeter

I learned a lot of crossover stuff from playing around in VituixCAD after seeing a youtube video from KirbyMeetsAudio about designing your own crossover. The video helped guide through the slight learning curve (for a total newbie that I am) for loading FRD and ZMA files into the Vituix, and the video kind of pushed the idea of fooling around with parts and values in that virtual space to see what things do.
Sadly, the newer versions of VituixCAD, while still free and more flexible than ever, are a little less newbie-friendly with the crossover building than the old version that I started on.....not a huge difference, but I can imagine it being more daunting if you're as new to it as I was.
I like that the program keeps most of the important graphs/information all in view at-once, making it easier and more intuitive to see changes in real-time whenever you tweak things a little.
At first I was making beautiful smooth frequency response lines, but quickly realized the impedance graph was falling way too low....feeding a largely 1ohm load into most amps will make them overheat (hopefully turning off before breaking something).
The old version 1.1.33.0 (from 2018) has a lot of pre-configured crossover parts you can easily plug-n-play with...I think the newer versions replaced that with a very free-form drag-n-drop part by part system that's fully flexible, but the old preconfigured parts were a good learning tool. :(
Do you kind of have a rough understanding of regular crossover stuff like first-order and second-order LowPass and/or HighPass builds?
I didn't, and I'm not making fun if you don't either. Just trying to get an idea where you're at right now.

Man, from the reading I have done it seems a lot of experimentation is required to balance the boomyness of the lower woofer against the upper one and that just tossing an inductor in series with the lower one isn't going to work well.

This just got me wondering about a center channel I am cooking up. I have been on a kick with these, and I now have it in my head that I want to make a 2.5 center. Probably.
I have four Dayton ND64-4 : 2 1/2"
and some tweeters I could choose from to make a "MMTMM" of sorts. Kind of weird calling a 2.5" full range a "Midwoofer."
Tweeters: AMT MINI-8, ND20FA-6, DC28F-8, a few MCM 4ohm cheap ones,
I was thinking (not that hard) that I could wire up the four ND64-4 into series / parallel to retain the 4ohm load, but I forgot about the crossover and that I have no idea how to go about planning out a 2.5 at all. I haven't ever even put one together. A 2.5 that is.
Where do I go to learn / figure this out / find the shaman to guide me?

I think the larger B4N's extra headroom means the simpler 2way B4N-MTM version can mostly keep up with the larger and more complex 2.5way B3N-MMTMM allbeit in a slightly taller box.

Not exactly what you want, but this 'CENTER' has m5 and m6 in it...

a4eaudio understand different different cabinet size and even cross over. I wander if Paul Carmody or any cool folks here modify OS MTM -> OS MMTMM Center with B4N ;p
Would be interesting see performance/tradeoffs/etc for MMTMM w/ B4N vs cute MMTMM w/ B3N ?

Paul and Gents,
I wonder if anyone build/design the OS CC with B4N for lower bass instead of B3N?
Thanks
Ken
