Experiences with Textreme dome tweeters anyone?

[flex2]

Well what I am really asking is would there be a sonic difference. I did read the review before you posted it and of course he loved it. However, could a tweeter 1/3 the price compete with the Textreme? The ScanSpeak 3004/6660 is on sale right now for $235

I would say no, that tweeter from Scan-Speak stores more energy below 2kHz and that will be heard as a colouration.
I have tried a couple of Scan-Speak tweeters with that same back and damping, and they sound a bit coloured. I do not favour it.
In an effort to be able to reach the lowest possible frequency response 27TAC/GB also stores some energy.
I would say that TW29TXN-B have a slight edge in performance, and also benefits from the shallow waveguide of 3-4 mm that will help to reduce diffraction.
I would not rule out 27TBFC/G and 27TBC/G from Seas. If you add a 3mm shallow wave guide to those drivers (100mm outside diameter) like TW29TXN-B have you will be surprised how good they perform regardsless of price. Both have less stored energy than 27TAC/GB or any of the Scan-speaks.

Linearity of distortion is important and 3rd harmonic needs to be 10dB lower than 2nd in all registers.
If not, you will hear some sharpness and edge. TW29TXN-B is the best I have seen regarding linearity in distortion in combination of very low distortion.
I would go with that tweeter if cost is no object and Seas 27TBC/G on a budget.

Yes, I use the 27TBC in a waveguide Visaton WG148R. The result is awesome. Use it starting at 2kHz.

Thank you @flex2 for your suggestion. I did some research and that is definitely an awesome driver. The only question is does the protective wire over the dome protrude? The grill cloth on my speaker is like a sock stretched around the cabinet (see pic). I need a driver with a flat profile where the dome doesn't protrude. I looked at the photo of the driver side view and it doesn't look like it protrudes but I cant be sure.

Out of this picture it seems to extend approx 1 mm above the front face.

I can deal with 1mm, thats nothing, the Seas protrudes slightly as well you may even see it in the pic

So I am running these with Conrad Johnson Premiere 12 tube amps. Wondering if I should go with 8 ohm or 4 ohm version.

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.

I ordered the caps today. I'll post again after installed. Ive read that they need some run in

They can take some time, but nothing like 100 hours or anything. Just don't judge them hard for a couple days of use.
