Have you tested tweeter with a multimeter, to make sure that is the problem. Could be crossover or other issue.
 
Thx for answering Old Guy8
No, I don't even get one... I'm not an audiophile technician yet, I've always listened to music without asking me to many technical questions.
But now I'm facing a problem that need a little knowledge.
I'm going to get a multimeter and learn how to use it as far as the tweeter did respond at the beguininng and stopped.
 
Dave, wait for someone more of a tech than myself to hopefully chime in to help you solve it faster than I. Don't order a tweeter til sure it is bad.

Dave,
It is a possibility that could be a loose connection to the tweeter or other break in the circuit to the tweeter. Are there any tweeter volume switches on outside of speaker? Take a picture of speaker front and back where wire binding posts are. I want to figure easiest way into speaker. Would you feel comfortable doing a little disassembly of your speaker. Want to take pictures as you do, so know how goes back together. Especially any wires at speaker drivers, so positive to positive etc.
 
image.jpeg There's a chance of a loose connection A quick look inside showed no apprent pb if connection.
Here are a few pics.

I will pay more attention to the pb this week end. The tweeter may be ok this is what I hope... I'm investigating !
 
Dave,
If you can borrow a multimeter. Or, if you want to buy an entry level one for about $10. (Meter can be valuable for other projects.) You can check direct current ohms reading across the two terminals of the tweeter. Might have to unsolder one wire to it so meter can't find another route to complete circuit. Meter should have instruction how to zero meter, first. If you get a few ohms reading, I THINK it might be ok. May be a safe way to check with a small battery, but I don't want to try on your speakers. I'm not a tech. Keep track of where wires were connected, so polarity is maintained when reassembled.

Sure I think I'm gonna get one it can be useful.
There's also a coil or something like that between the connexions wrapped in black plastic maybe the pb should be there ?

Possible there can be a problem with the coil, but I believe bad capacitors more likely. Two caps on right wired together. I think the silver with red ends device on woofer is another cap. I DO NOT know how to test the caps. Someone else will have to chime in on that. Are there any resisters? I had a bad resister in an Advent once. When you find out what is wrong, you will have to decide if you want to spend money to fix. Capacitors or resisters should be available and reasonable priced. Tweeter maybe not. Do you like the speaker that works sound, before you spend money?
You also could try the tweeter you know works, in place of one that does not. Extra trouble, but I don't think at low volume will damage it.

Thx for the leads !
Yes they deserve to exist the sound is great deep and precise I had before a pair of davis bass reflex which are not as precise as the EMI.
I'll try to figure out the pb this wk and keep you posted.
There's a reference shop in Paris specialized in speakers if I can't fix it myself I'll go and consult them.
 
Dave,
Did not notice your location. A lovely country and people. Was visiting Paris with Normandie and Burgandie as tourist two years ago with my wife. Good luck on your speakers.

Glad you enjoyed !
Beautiful people are everywhere ;-)
Never been to illinois but met a bunch of great people in frisco back in 2001 and 2006 while chasing records.
Thanks for taking care and your advices, and above all for taking time to answer I truely appreciate.
I'll keep you posted on evolution of my investigation ! Knowledge is king !
