Thiel Owners

since the one tweeter is not working and Rob thinking that it could be a lead wire 

you could try to re-solder the wire connection where the speaker cable attaches .

sorry about spelling your screen name wrong ,

2 things , are you sure it's the speaker ? have you switched them ?

when re-soldering have your iron just hot enough to melt the solder ,

also check the speaker wire soldering .

you don't want to heat up the wire going to the voice coil .

I second jonandfamily's request for direct experience with the soft dome for the Thiel UltraTweeter.

I removed the bad tweeter and measured open circuit on the multimeter (the good one measured 3 ohms). I have sent both to Rob for the soft dome rebuilt and will report back later. I will also be looking for 2 original pre-used tweeters as backup.

In the eventual realm, I am working with ScanSpeak (Vifa) on a 'new' tweeter in that motor frame. My target diaphragm has the potential of greater specific stiffness than aluminum without the ringing and without the high expense of carbon. Work in progress. 

For now, that soft dome (I don't know how soft) was engineered to fit that motor and alleged to be plug-in compatible. Jon, see if Rob can make a frequency sweep for you on both driver types so we can compare and contrast.
