Seas T25CF001 vs SS D2608/913000
Has anyone heard either or both? Thinking about crossing at +- 2800 to 3200.

I did a tweeter shootout some years ago and compared both of those (and whole lot of other tweeters). They actually sounded really similar. At the higher crossover points you have specced I would go with the Scanspeak.
I've actually tried both in the same box with the same midwoofer (Seas ER18RNX), the T25CF001 crossed at 1k6, the 9130 (actually the Peerless HDS, same thing) at 1k5. I agree with augerpro, no big difference as long as the rising response of the SS is controlled in the crossover. I expect even less of a difference crossed over that high. I assume it's for a 3-way? I'd go with the SS too, cheaper and smaller faceplate for easier front panel positioning / getting it closer to the mid driver.
Yes it's for a 3-way.
I'm leaning towards the SS because of the reasons you just mentioned. SS recommends to cross the tweeter at 3500 in their data sheet, something I don't see why, as fr and impedance is nice and flat way before that. Guess it's more at ease at higher frequencies.

You can safely ignore the "Operating frequency range: 3500 - 20000 Hz" thing in the datasheet. That tweeter has stellar (regardless of price but especially for the price) THD performance as you go down in frequency, as I said I've used it down to 1.5kHz and it showed no signs of stress. I guess they quote that figure to keep things safe, note that the power handling figures are with a 4k, 2nd-order crossover, so they don't want people complaining that they fed it 400W using a lower crossover frequency and it went up in smoke... And why not quote those figures at a more reasonable frequency, say 2kHz? Simple: because 400W looks way better on a datasheet than 50W or whatever the real power handling is if you cut it lower...
Likely, however as SS states "4000 2nd order" you'll have to reduce you power handling expectations compared to the data sheet.
Years ago a guy from the USA posted here who produced a range of waveguides, among other for the HDS/SS tweet.
From the measurements he posted on his long defunct site it appeared as if the rising response could be taken care of by simply sticking it in a waveguide.
No guarantees though, it was some time ago.
If you're going to be crossing over around 3kHz why not go for a small neo tweeter and get the spacing to the midrange even tighter? There's no point in going for a full sized face-plate tweeter if you aren't going to use it down low.
As people here seem to be saying, heard one 25mm or 1" soft dome, you heard them all:

Haha, the midrange will be an er15 or er18 so fear not. I've heard lots of great things about the tdfc and tffc. However I want to step it up another notch. Of course if the tdfc and tffc is as good as the previously mentioned I'd go for one of them. Though as far as I know HD is higher on them?
I'll be using a pretty small midrange, so the centre spacing will be within one wavelength at 2800. I haven't quite understood the importance of it as basically none of especially the high-end manufacturers seem to be bothered
No problem with supporting local businesses, but sadly, not all 1in soft domes are created equal. Try plugging in a cheap Goldwood and compare to the Seas 0881 you mention. 😉 That being said, quality domes can sound quite similar, especially if EQ'd to the same baseline response curve, since they will likely have similar dispersion & distortion profiles. Of the two in question here, the Excel might be a touch cleaner in terms of linear distortion, but the 9130 beats in on non-linear distortion, so may be a better bet with lower XO frequencies.
Thank but no thank you. I support companies that make their products where the company is based. Seas and Scan speak being two of them.
The fact that they don't always bother doesn't mean it's inaudible; it just means they haven't done so for a variety of reasons. Sometimes people prefer to trade it off when necessary for enhanced performance elsewhere (say, IMD). Sometimes it wouldn't fit with the aesthetics demanded for marketing. Sometimes you are obliged to use given drive units & it's not possible. And so on & so forth. You make your call based on information and where your priorities lie. All other things being equal and assuming a good acoustic environment, consistent polars are generally better than inconsistent.
No doubt. Especially since that cheap Goldwood doesn't sound anything like the 0881 (TFFC) Steve mentions. 😉
Definitely not! 😀 If you haven't seen some of those inexpensive Goldwoods -let's just be polite and say they perform like they cost. In many cases, it's not pretty. They have their place, but high performance audio is not generally it.
