These specs don't seem to be posted anywhere so I'm hopeing someone here knows.
Looking to make a 2 way with the audax and TB but the audax needs to be padded down. I could test the audax myself, but, I don't have any and would like to order everything i need at once.
On the TB side, I can't find the Le for the W4-616S anywhere. I would like to order parts for a zobel to play with.
If anyone can help that would be great!

The Le for the TM025F1 is not available at the Audax website right now.
However, Audax made the TM025F1 the tweeter in the home theater setup designed by Joe D'Appolito. It includes 3 different crossoveers for the tweeter, one at 2650, one at 3500, one at 3000. There was not a Zobel network in any of them-perhaps it is not necessary.
By the way, the Fs of the TM025F1 is 1090 Hz. Where do you plan to cross over?
www.madisound.com has the audax catalog available in pdf form. Unfortunately it does not have the info you seek. Also, I have put a graph and info for the tweeter at the following thread:

The D'Appolito designed crossover schematics and general setup are available in the following pages in the "Do It Yourself" section of the Audax website, www.audax.com:

Yeah i had looked at PDF's all over and even the audax site but the Re is not listed anywhere. The Audax HT x-over was helpfull but i need more attenuation(is that a word?🙂 then the audax HT x-over gives.
2500-3500 for the x-over, not sure yet. The Tang Band can certainly be used higher but...

Here is another crossover which appears to have a Zobel. Only thing is, the author might not be an electronic engineer, but a hobbyist using software. At any rate, he seems to be using the design software competently, so his crossover bears considerations

The Le might have been listed at the Audax website, which has had the product parameter feature nonfunctional for the past week-except for the aerogel woofers.
PS: The Audax .pdf contains another tweeter with the same resonance frequency, but it is not ferrofluid and possibly not neodynium. Still, an Fs of 1090 for two tweeters from the same manufacturer would tend to indicate the same voice coil, don't you think? check out the Audax .pdf for that other tweeter-maybe that's the spec.

Success at last.
Solen of Canada lists the Le for the Audax TM025F1 as .04 mH.

Ha! Thats great. I had looked all over and never saw the Re for the audax anywhere(suprised audax doesn't list it).
Thank you very much!
I *should* be good to go for the most part now. Some have said i need to look into baffle step for the Tang Band, though.
Any reason not to flush mount the audax? A few have said it doesn't need to be but it's not any extra work to do so.

Did you want the Re or the Le? Not that it matters-both are listed.
If you cannot find the listing for the TangBand, I downloaded Driver Parameter Calculator from Steve Ekblad's site and it calculated it, from an impedance graph and formulas, as .29 mH.
The labelling on the response graph by Tangband is obviously off, since an 8 ohm rated speaker never is shown as never going below 18 ohms according the graph! Obviously, where it reads 20 ohms, it really means 10 ohms, etc. this graph is from the Parts Express site.
If you want details as how I figured this, will explain tomorrow. Suffice it to say that the bottom of the impedance graph should be 0 ohms, not 10 ohms.
The graph is available here.

I used 10000 Hz as the frequency, and the ohms was 19. Once you realize the impedance markings are off by 10 ohms, (10 ohms line should be 0 ohms, 20 ohms line should be 10 ohms, 30 ohms line should be 20 ohms, etc.), then it all works out.

Good luck. Will answer any further questions you might have tomorrow. This is the first time I tried the program myself. Tomorrow, I might try seeing how it agrees with the published specs for woofers where the Le is published. I won't be able to vouch for the program until then. Just thought you should be aware of the option in case you cannot find the published spec.
Will post on this again tomorrow. 🙂
