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.

After you fix the problem, I would replace all the electronics to the level of the speakers.  Emotiva with Wilson should be bright as hell.  I am talking ice pick bright!
Hi Erik , I never touch the internal of the speakers . I hear the mids clearly , it’s definitely the tweeters . How do I open and remove the tweeter and midrange, just by removing the screws from both I should be able to pull them ? 
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.
