Based on impedance plot, looks like ported enclosure. I would guess that IM for mix of spectral components in 20-500Hz range is messy.
Do you mean damp, or attenuate the tweeeter ?.
On the contrary, your input is most welcome....and I did ask.
Troels Graveson documents a TL kit incorporating the Raidho tweeter.
What is the price and availability of this very well regarded tweeter ?
Rod Elliot has discussion about series crossovers - ESP - Series vs. Parallel Crossover Networks
Dan.
Another very good text is Doug Self's book on active corssover networks. There is a section on the comparison between parallel and series types of Saleen-Key type networks. A very good read if you have not read this book.

Thank you for replying.
I am sure you know that resistors in a (possibly formed) tank circuit can only act as dissipative elements reducing the Q of the circuit.
All right. That’s a good place for investing in diamonds (*)
sp3 solely, no sp2 bonds? 😉
Now this is a perfectly clear (moebiusless) description. Two 0.9 Ohm non-reactive resistors in series with the 8 Ohm partly reactive tweeter. They surely lower and broaden the resonance peak
We enjoy technical details. Besides, you were asked to inform us
The open back construction places the already damped resonance much lower in frequency, that’s very good.

(*) My reference to gem stone in my previous post was tongue-in-cheek.
I hope you don’t really support anything from the Moebius coils (what a make-up) paraphernalia.
George, applied to audio there's a gold mine here. Mobius Coil Tutorial
Succor Punch, a new one I love it.
About 8-10 years ago, the tweeters were sold, tries made a kit, but sorry the tweeter is only for Raidho use.
The main advantages of current diversion (serial) filters are that changes in the bass driver at large amplitudes is reflected in the tweeter and the fact in the crossover band the drivers share current and as such they are phase locked to each other, also under high woul me transients, this makes the soundstage much less nervous and makes the"picture" better rendered with more and sharper contrasts.
Also some SP-2 bonds,<45%, this is the reason why the color is blackish. On a 41/2" membrane, there's something like 1,7 carat worth of diamond, but I suspect not the kind of gift you'd prsent to your girlfriend..🙂

I still remember the first time I saw someone in a restaurant waving a crystal pendant over their meal to see if it was good to eat!
"I was given the design for the mobius coil by Gentry Smith, who got it from Flanagan when Gentry was his research assistant in Tucson. At the time, Flanagan was involved in a US Navy 'dolphin-communication' study, seven storeys underground in the desert. " ----Don Croft
This sounds legit to me. After all, what better place to communicate with dolphins than the desert?

merely reading this tripe makes me sick, and I am continents away.
Just what drugs are these retards on ?....

Max,
Now your being objective instead of subjective, you just need to make that Mobius coil and try it first, you could kill all those parasites lurking everywhere! And those sand dolphins are top secret, supposed to be sent to Iraq to swim under the deserts and they are taught Arabic so they can tell us everything people are saying. 🙄 😀

starting? That was happening back when I was a teenager. Before then real men cast their speakers in concrete!*
* I kid you not. The late John Crabbe later editor of hifinews in its objective years did that sort of thing.

Amazing.
I created, prototyped and measured and published the results.
It works very well. It will significantly lower the driver output distortion - esp in the low frequencies.

Doubly interesting. Can you point me to the article?

I may be that mobious coils are in use for a lot of things including some quite alternative, but for me it's nothing more than a simple way to make a high power wire wound no/low inductance resistor. See as the current move in two opposite directions and thus is the inductance cancelled. We have always made most of our resistors in house at Raiho, in the beginning we used carbon rods as they had negative temprature coefficient and thus they at least in theoriy shoud be expansive as opposed to resistors with a posetive coefficient.
While the low/no inductance effect of the möbius resistor may seem small listening tells another story

Assuming we are talking crossovers surely the effect can be easily modelled (and usually is)? Or are we talking below the point where there is any effect on modelled performance?
Don't think you can see uH or below on any spl frequency plots. But then I never said that all you hear is measurable, in fact I have often said the opposite..
