Tweeters are silent on my Wilson audio Sofia 2


Hello everybody, I’ve had the Wilson Audio Sofia 2 for over 10 years , always had a feeling that there were lacking the crisp clear highs I’ve enjoyed from the previous Sofia 1 .
I changed locations , amps , speaker cables , processor to no avail - still very muffy dull sound lacking treble/highs in all types of music , in both stereo and multi channel .
I already changed the resistors - no change in sound .
I hooked up to the same set up other speakers from another room (SVS Ultra , B&O) and also my center channel Wilson Audio Watch speaker and I am getting great sound so I know it is not my gear that causing the issue.
Gear used :
Speaker cables :Transparent reference MusicWave Super.
Amp : Emotiva XPA 2 -Gen 2 & Outlaw Audio 770
Processor: Marantz AV8805
CD : Marantz 6007
Subwoofer : Velodyne DD 15
Surround in wall speakers : SpeakerCraft AIM Cinema 5
Interconnects : Mogami XLR for main and sub and Transparent audio RCA to rest of the speakers .
Did anybody encounter or heard of this issue ? Any input is greatly appreciated.

Did it take you ten years to figure out your tweeters were not working? and you call yourself an audiophile?
@OP,
Please ignore the above comment.
The rest of Audiogon is here to help.

Hi OP!

Unfortunately I can only go by pics I see on the internet. You should be able to do all the testing I suggested via the jacks on the back.  Disconnect the speaker cable and measure across the tweeter jacks.

Best,

I'm going by these images:

Based on that, in the rear the left jack is for the midrange, and the right jack for the tweeter.  Disconnecting that speaker cable from the lower cabinet should let you measure the tweeter directly. Your average multimeter here will let us see if the tweeter voice coils are open or shorted or reasonably working.
Sorry, it seems that I'm not looking at the back of a sophia. .... let me see what the manuals say.
