Probably should have done this a long time ago; don't over think it. Ok it's a Zaph kit, very popular and it has been a around a long time. Both drives from the Seas Prestige lineup - and an appropriate title.
Just bought the drivers, have plenty of crossover parts.
They sound great, way more bass than expected. The first attempt used Ironcore inductors, woah, that was an eye opener. I thought my amp was shorting out at higher volumes, clipping I suppose. The remedy was easy enough, replaced with 14g air-core.
Not giving up on double double woofer boxes or the wavcor tweeter, they work beautifully with an active setup @ 1,500hz wow!

Set up:
(1) PC, USB, Dacmajic Rotel 200watt
(2) Smart TV (with AM app), Toslink, Dacmajic Rotel 200watt

Ordered drivers for a similar Zaph project, uses Revelator's 7"s.

Well I guess you could call it a different sort of adventure 🙂 If you decide to make as many kits as you have other speakers you will kickstart the economy! 😀

Crossover Question
The new drivers are here, have all the components except the 18uf caps
However plenty of 20uf on hand.
Looking at locations, can I use the 20s?
Thank you for any suggestions in advance,

Absolutely. It's on a shunt, only 10%, and there's added resistance on that leg.
If you had one with 20, and one with 18, I doubt you could tell which was which (blind).
We do tend to overthink things. It's the hobby.

Overthinking, unfortunately yes.
I checked the website and grabbed this photo, noticed two things, the inductors are laying side-by-side and using an Electrolytic Capacitor.
One reason I started this project is a stash of foil-coils on hand.
Typically use Brass or SS screws to attach them to the inside of the box, idk, probably not needed, but they don't cost that much either.
Thanks for the advice!

I'm getting tired of waiting and fooling around, I'll find somebody who won't make me feel like a clown, This can't go on... Lord knows you got to change
(Sorry, could not resist!) 🙂

What Zaph kit is this ODougbo?
Zaph|Audio
I was curious because I never understand what 6X2 15W means.
I have a notion that crossover frequency as Radians/sec is SQRT (1/LC).
LC circuit - Wikipedia
Anyway bottom line is 10% tolerance change on ONE component produces 5% change in crossover. So I agree with boswald.

System7,
I did not see it on the Zaph link, but it is a Rediscovery II
Scan-Speak ReDiscovery II Kit Expensive but saved on crossover parts.
The pic on the OP is a SR71, I'm not expecting a huge improvement, maybe there will be a surprise.
The double resistors - they are stacked/parallel 3ohm 30watt, 90% positive anyway.
Thanks for stopping in.

I couldn't find those resistors in the woofer circuit anyway, but found a online calculator and ended up using a combination of three to get down to 6ohm.
Well anyway coming down the home stretch on the build.
We're having a lot of fun with the Seas build; they sound great. I pulled out a Luxman M-117 from the bottom shelf and listening to that via laptop/DAC.
I'll give Luxman a shout out, that amplifier does has a unique sound quality.
Once this pair is done, I'll set up the mic and measure both pairs.
btw, in a few more days I'm going to have a LOT more free time
