I don't know about the warmer of the two since they sound very similar but I'd give the edge to the TDFC.

Both are excellent tweeters though.

Well, I'm exactly in the same situation!

I have a 2-way speaker and I own two older Vifa tweeters, D26TG-35 and D26TG-46 (with rear chamber, nearly identitcal, just slightly different cone materials).
I'm curious to try one of those Seas tweeters instead, but can't decide which one!

Can anybody tell which are the audible differences between those two tweeters?

Thanks a lot!
Martin

They are both good tweeters but I prefer the 27TFFC as seems to have more air and more natural than the 27TDFC. For higher power applications the 27TDFC would be better as it's more robust. In the end it's all about personal preferences.

Troel's has a note about them in this build.
Poor Man'

I haven't used those Vifas but have used the D27TG-35-06 and the SEAS are better but I'm not sure if enough to warrant a change. Also the crossover would have to be reworked which can make or break the sonics.

Thank you Rabbitz,

that's interensting! Perhaps I should go for the H881 then. But I also think these old Vifa tweeters aren't that bad. It'll be an interesting comparison. The crossover is in revision already, but I think it will be nothing else than a single 4,7uF cap of finest quality. Despite all drawbacks I just can't get happy with more than a single cap. With steeper filters the sound always becomes a tad more "correct", but also more artificial and "Hifi-like", if you know what I mean.

Regards!
