A throwback to when I was 18 YO.
I'm finally going to use the Kicker EX124 drivers in a biggish box and a pair of SB mid-bass I bought off rabbitz; pre-Covid.
SB17MFC35-8
But I have a small problem here as my copy of Jeff Bagbys Passive XO and his Box Modeller no longer work.
Might take me a while tho as I have to clean up the shed first.
I read Jeffs posts [ RIP and sorely missed] about his Universal sub crossover and thinking that as I like to keep things as simple as possible I'd go with a first order electrical on the woofer as low as practicable.
But looking though my stash the only large value inductors I have are cheap laminate cored from Jaycar @ 9mH / 19AWG and a DCR of 1.9Ohms. I usually buy in pairs but I seem to have only one 5.6mH inductor there and that value was what I was going to use.
So I'm now wondering if I should make a true 3-Way crossing around 250/300Hz or simply going with a 2.5Way using a wide baffle and setting the woofer at the baffle step -3dB.Because I want a particular sound for Hard Rock I'll be using the venerable Vifa aluminium dome D26 tweeter and crossing somewhere around 2500/3000Hz.
I will be playing LOUD most of the time, these may live in the shed or be gifted to one of my kids later on.
Thoughts and prayers?

Its published specs would make a nice BP6 for loud, so no low pass, just damp its upper harmonics.
You must've been 18 a long time ago, Kicker dont even list specs for the EX12-4 is that an early 90's sub?
Cant even find one on a search, sure its not a C series

EX was a driver sold only in Singapore and Australia. Pretty much the same as the CX but slightly higher Fs and yes very early 90s.
I got a couple of NOS really cheaply
You know what they say; "If you can remember the 60s you weren't really there"

I was going to put them in a 35 litre sealed box [ Qb 1.1] with a large high pass capacitor in series; the same as I did for the EX154 I still have and use for parties.
A little on the high side same as for vented, so tuned a little lower.
That said, just realized I have the ES specs and worse was looking at the 154, so @ 2:33 am I wasn't as alert as I thought I was 🙁, but I've done up to 0.5 Qt BP6 that worked well once tuned empirically and vents critically damped.

Have you recently updated to a newer version of Excel? PCD has different versions for different Excel.
No rabbitz I'm still on version 7 on W10.
For some reason all the macros in Excell have stopped working, not just PCD.

OK I just did that and now I get a header that says ( Read Only) I was stilling learning on that program too.
Also it keeps asking me for a password and I've never password protected the program or any of the files I saved
Its got macros embedded so some of your windows/Excel settings may be preventing them from running properly.
WinPCD is a windows version of Jeff's PCD that does not run in Excel. I think it runs in Windows.Net but I don't really know what that means.
