Hi I am currently using a 27TAC/BG in a 12 inch 3 way system. I am considering trying the Satori or Scan Speak version of the Textreme dome tweeters. Has anyone used them? Are they of higher performance tan the driver I am using? Thanks
Looking at the frequency response curves, the Satori TW29TXN-B-4 TeXtreme-diaphragm tweeter seems to have a performance edge over the 27TAC/BG. The TW29TXN-B-4 has a much better damped high-frequency resonance, albeit it is outside the 20kHz upper limit of hearing. What's left can probably be attenuated relatively easily if so desired. The TW29TXN-B-4 is also about 5dB more sensitive, which can help a bit with power handling. Maximum linear displacements of the two devices are quite similar. At 10kHz, the dispersion of the TW29TXN-B-4 seems to be a bit wider, which may or may not be beneficial in the typical listening environment.
The general performance of the ScanSpeak Illuminator D3004/6062-00 TPCD Textreme dome tweeter seems quite similar to that of the TW29TXN-B-4.
It would be interesting to see the harmonic distortion plots for these three tweeters.

If only we had a resource that has this type of data.... 🙂

And 27tac

I use the satori tw29txn and I am very pleased. I haven't heard the seas, but I've read numerous opinions that are solid performers.

That is not perfectly true, satori has much more sensitivity, at the same sound levels satori should have much better Distortion profiles than the 27tac
You cannot only consider the tweeter it self. In a 3 ways if cut above 3kHz, to make a real difference is very hard if the design well is executed. You can use the extra money to buy better capacitor. Honestly I use a lot SEAS metal tweeter, and I am never be disappointed by them. They have a very good price/ratio.
Being I've used this tweeter twice, I can say with certainty, you need to try ASC X387 or X386 poly in oil caps. RS Components stocks the widest collection I've found.
Interesting to know @jimbones why you want to change tweeter ?
I use three SEAS metal tweeters in several designs : 27tbcg 27dxt and 27tac. The 27tac is to my ears too discrete, too neutral and the response curve is the least linear in the three after filtering. But it works well. The idea to use the ASC capacitor is a good starting point to have best results.
I would go to test textreme cone with Helios TX but ask myself if I better replace the textreme WG tweeter by a compression and I am sure to have a better blend with the textreme woofer, but don't know if the textreme woofer wo24tx is really a step up above the paper woofer wo24p, I prefer the response curve of the paper woofer, it seems to have a better behaviour in the entire band. But hard to find a lot of subjective opinions on textreme speaker. But two of them on this forum seem to say the midrange is not the strong point. I always think carbon cone is good in the bass area...

I have been a fan of the poly in oil ASC since 2010 when comparing against the old Clarity SA caps. More space than the SA, smooth, and detailed. I've used them on quite a few builds now, including the recent Drottnar and Monoculus.
I used a bifilar mylar/paper in oil 2kV cap in the other 27TAC build. Different, but still good.
