I pasted the above pictures in Inkscape and tried to guess the sizes of the wings of the Manzie (GRS version): they should be quite correct-ish, so here they are.
425/500 for the front wings are of course indicated in mm and not cm: 42.5/50cm.I pasted the above pictures in Inkscape and tried to guess the sizes of the wings of the Manzie (GRS version): they should be quite correct-ish, so here they are.

FYI - found this while surfing the web. 15AWG 5mH, 6mH, 8mH, 10mH Iron core Inductors. They also have some Audax drivers, Tube amp transformers, etc.....

Ho-ho! I'm hooking up the crossover and getting myself ready for a long and exciting(!) listening session.
Very nice work.
Which woofer are you using ? The 15” GRS 15PF-8 has a much smaller magnet.

Thanks @e_fortier
Oh my... You're right! It seems I f*cked up and ordered the wrong woofer. GRS 15PT-8 instead of GRS 15PF-8:

I remember opening the shipment from SoundImports, looking at the huge magnet, and thinking, "Is that a small motor?!"
Well, the Manzanitas are singing, but very bass-heavy...

That’s a tasty build. Is the top piece (kinda like a shelf) acceptable with the 12” version? I’m starting a rebuild in the new year with some walnut (and the assistant of a friend with woodworking skills).
Thanks, @Alistair72
I don't think/or hope this top piece will do much harm to either version of Manzanita. It's only 4,8cm depth. The reason for it was entirely aesthetic, to cover up my sandwich baffle.
Walnut is nice! Looking forward to your project. Please post some photos.

Why?Unfortunately, this is no longer Manzanita.
Care to elaborate?
Blank statements will get you nowhere.
It's a Manzinita, mostly. But with the different magnet you would need to do some changes to the crossover.
The 15PT is much more sensitive than the 15PF for which the crossover was designed. That is certainly going to make it bass heavy.
You can experiment with the series resistor on the tweeter. If you have clip leads, just bypass the resistor and have a listen. If no clip leads, you can figure out how to bypass or remove the series resistor. Doing that should put you closer to the proper tonal balance. Have a try and let us know.
That would be R1, the 8 ohm resistor in series with the tweeter.

This should get you close to matching woofer and tweeter with what you have now. If you have parts near these values, give it a shot.
87dB vs 93dB is a lot so I will adjust the crossover tomorrow. It's not soldered yet but hooked up with Wago connectors and a breeze to experiment.
It is late night in Norway, so it's time to hit the hay. Thanks for your input @Pano
Edit:
I have different types of resistors but only 6µF cap and 4.7mH coils.

A little update:
With the toothbrush in hand, I removed the 8ohm series resistor and gave it a listen. The bass is what it is, but more gain to the tweeter made the tonal balance much better. I can live with this while waiting for the new woofers.
