Dead Vifa d25tg-01 in M&K S-1B - any vifa experts out there?

What replacement options are there? Stock tweeters are:

d25tg-01 6 ohm units

Will other variants of 6 ohm D25TG's work such as D25TG-06, 55, etc.?

Looking for options and wondering what the smartest way to source a replacement is and what falls within the realm of being the same driver. Thanks in advance all!!

Other Vifa tweeters may work, but if the SPL's (efficiencies) are different, it might require a change in the crossover resistors that affect the tweeter level. If you can get more into on the originals, compare resonant frequencies (fs) and SPL's. The impedances look to be OK.

Update: Your tweeter has a resonant frequency of 1500Hz, a resistance of 4.6 ohms, and an SPL of 92 dB. The Peerless/Vifa D27TG35-06 (available from Madisound) is pretty damn close on all of them. The resonant frequency is quite a bit lower, but that's OK. The biggest issue will be modifying the mounting plate to fit.

I can't find specs on any of the entire line sadly, it was one of the first things I checked. Where did you find the specs? I wondered if the D27TG35-06 was close. There is someone on audiomart that has 2 x d25tg-06 6 ohm units that I am contemplating as I'm guessing being from the same line they would be close, failing making that determination I'll take a harder look at the D27TG35-06. I had read in other forums that was a similar recommendation.
 
Crisis averted. Justgotohm another fine AK'er just sourced me one from the exact line that i have. Thanks for the help!!
