The last 2 tweeters I bought already had capacitors soldered to one pin of the tweeter.
They were both 2u2 250V capacitors. Polyester I think.

Bob,
I never mentioned tube amps because as most know(or maybe they don't) they have transformer coupling in the outputs, which of course blocks any DC going into your ribbons primary winding.
Your post goes into calculating xover freqs etc etc, which most of the thread already covers.
My post was merely to point out that some ribbon tweeters have primary windings that can have very lower DCR which most solid state amps or at least any of the ones I've designed/built over the past 30 years won't like when used with a direct connection, which the thread never touched on once.
As for your comment Jon, I guess you're just lucky or you're using special amps, lol.

Jon, do you have a link to the ICE amps you use? And yes in this case the best cap is no cap, if you can get away with it.
at this very moment i'm using the ASX series, but if i replace the DEQX for a 4x10, i'll go with the newest 300ASC modules

For me, the Amplifier question is settled for a long time now. I'm glad i don't have to worry about it anymore... Still remember when i was spending big bucks on Classé, Ayre, etc... Oh my...
I didn't know the Ice amp could drive a load that is essentially zero ohms for DC. I've been avoiding switch mode amps since I hear they blow up for no known reason once in a while (and blow the speakers too). I figure I'll let that technology evolve a little more for now.
ICE has been the most reliable and enjoyable amplifiers i had so far. Would't even think to come back to what i had before.
@Bob
Actually they can drive some surprising load. My 1000ASP's drives 2x 10w7 PLUS 1x Volt midbass in something like 1.3ohm load, and i push the w7 with nasty EQ boost in the 20-30hz... had ZERO trouble, not even a single thermal soft-clipping

the new ASC's are great too. Can't wait to try the powerfull 700ASC2
i used 2x 700ASC in a project to drive a dozen (!) 10w6v3 and, while obviously underpowered, they push a lot of air...
