It seems that when it comes to quality/price, this price is the best in Poland. Try to ask how much I will send you to Australia. This is the perfect coil for this project.
When I bought the ERSE 20mH inductor, it cost $60. Jantzen coil price isJantzen coil price is $90. Considering inflation and the lower coil resistance, I don't think it's a bad price
Well, I consider $300+ for a single coil, being that low R, big diameter, flat wound, whatever, a very bad price.
Double that for stereo, then drivers, then other bits and pieces and Manzanita is no longer a fast, fun, inexpensive OB project.
I am a farmer but still haven't found a way to grow money on trees, or vines in my case.

I spent a few hours googling last night and I found these Mundorf MCoil BS140-22mH Wire Diameter 1,4mm and RDC 0,56 Ohm (https://www.mundorf.com/audio/en/shop//MCoil+BS140+iCore+StackCore/?card=1785).
It seems they are only available in Europe (several places stock them) and the prices range from around 55-60 Euro each plus shipping.
Still not cheap and cheerful, but at least they are available.
I also checked out the Jantzen Audio C-Coil 17AWG 20.0 mH (Toroidal), again readily available in Europe for similar prices, but I did see these following notes which concern me:
It is not recommended also to use C-Coils in crossovers with an XO-point above 1.20 kHz (due to the core’s distortion factor).

I built these 13 years ago and just now realized I never posted them here. They are Open Baffle, Line Array, EconoWaves.
The drivers are PE 69 cent NSB close outs.
The horns are JBL 6"x6" wave guides with Selenium D210T (JBL wave guide part 364914-001)
The cross overs are stock eWave - http://www.audiokarma.org/forums/attachment.php?attachmentid=151281&d=1242968714
They are 48" tall and 24" wide with the driver centers 6" from the edge and (top to bottom) centered on the baffle.

This is COVER YOUR ***🤭 This sentence also applies to ERSE, Jantzen and Mundorf coils. Do not worry about it.

Hmmmm. No comments? Am I way off with these instead of the Vifas? I do know there are differences but they seem pretty similar in a lot of ways.
Another quick update re the 20mH inductors: I ended up biting the bullet and purchased 2x Mundorf MCoil BS140-22mH inductors from Banzai Music in Germany (https://www.banzaimusic.com/Mundorf-MCoil-BS140-22mH.html)
The total cost including shipping was 107.93 Euros, and this was by far the cheapest I could find anywhere with shipping Downunder.
I will have to remove a few windings to take them back to 20mH, but that should be relatively easy, at least I hope so!

A 10 percent variation of inductance (22 mH vs. 20 mH) won't make much difference for such a shallow low pass slope (6 dB per octave). So I say don't bother to take turns off the inductor.
These were made by a local audionut near me back in Michigan. Those are Fostex full range drivers completely open in the back. The woofs are A15s. When I got them, they sounded very good but in time I realized they lacked midrange, so I built boxes to enclose the back of the Fostexs. Then I stained and cleared them. They really came alive. Needles to say, it was a very large sound!!!
Nice speakers, but this is a build thread about the Manzanita. Let's keep on topic please.
Ha, ha, ha,
To laugh or to cry, that is the question.
You are in the Manzanita thread, page 174, and asking what is the Manzanita?
Did you go through the first 173 pages before coming with this piece of brilliance?
As they say ignorance is bliss.
