Hi all, can anybody ID this tweeter which is one of two that came out of a pair of Wharfedale Diamond 2 speakers? I don't think it is the original tweeter which was a 20mm Audax plastic dome. It looks similar and is the same size but the back is different from images of originals that I have seen. The small print on the back at bottom reads K63TNM. If this is the part number I am not having any luck finding it on the internet. The red writing is the measured resistance across the terminals and they both measure about the same. The mounting disc is obviously cracking apart on both and will have to be replaced if I reuse these units. Any help greatly appreciated. Glenn

Look like the Audax to me except that the magnet is smaller?
Lots of clones out there and I think they all sound similar and not good really; but that is a personal subjective opinion.
These Audax tweeters were super cheap; aren't they still available?

there are several models from this Audax /speakers/car serie, the golded dome one was excellent.

Evidently some variety of balanced drive mylar tweeter, as the guys say. Visaton make them too.
The Wharfedale 3 dome tweeter was a goodish in-house Wharfedale driver as it goes. Looks like third order tweeter with, say, a second 3.3uF.

Probably anything around 90dB and 8 ohms will work. But you don't have much room there if the grille is still to fit, so 74mm or less I suppose. The cutout can be filed bigger.
I wouldn't throw too many Australian Dollars at this.
Simple crossover. 450uF series bass adjustment, a well known technique to make bass more present in a tiny box. No bass coil.
Second order tweeter, positive polarity. Probably 2.2R level adjust and 2.2uF series capacitor, 0.2mH shunt inductor.
I think I used to have the Wharfedale Diamond 1, on the left. Quite pleasant.

And tons of clones (i may still have some). I still have (or should) a se tof those lovely gold ones. Look really good for mounting on a phase plug to make a coax.
Many different bezels, many can be just twisted off.

I have located a possible replacement tweeter at Rage Audio in Sydney, Australia:
Audax TW010F1
https://www.rageaudio.com.au/index.php?p=1_11
Datasheet here:
https://meniscusaudio.com/product/audax-tw010f1/
90dB, 74mm faceplate. 4-5 kHz crossover I would think. $15 a piece.
Mike Chua of Ampslab has done a project with a similar tweeter in his Swallow.

I would email him for the circuit out of interest. He is a gent!

Thank you System7. Most helpful. I have emailed Rage Audio so I can place order. How on earth did you track them down? Glenn
You can still get a cloned shielded version here

They are two-a-penny Mylar tweeters. Search 'mylar tweeters' on Ebay - you'll find a gazillion. I have a bunch in a drawer here. They are often paired with small woofers because they are not very sensative.
I knew this would come up again. Found a pair of those tweeters (or clones). Cost about $13USD to get to Oz.
Have to test them first, and take a picture, they have a different bezel.

I believe the original used a formerless VC, which made them agile little super tweeters above 7-8k. So pleasant and underrated. Suprisingly resolving too.
Most of the clones I ran into weren't that good and neither worth the savings in cost.
I fitted these into an old Sony boom box, mounted to look like they belonged there and crossed with a 1uf film caps. Perfect combined with 5 - 6 inch FR drivers.
