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.

This seems like a very simple problem. If the OP still cant figure it out himself after all these posts he will need to send it back to the speaker company. Unless hes trolling us
Op should seek the help of someone in person, not here. No disrespect to him, but it is a special case to go 10 years and not correct a significant performance issue on expensive speakers. Call in the troops. 
@jimofmaine Agreed. Any competent local tech should be able to figure this out relatively easily. 

@jetset Do you live somewhere with an audio club? If so, you might reach out and see if anyone would be willing to come over and check them out for you (or recommend a tech that does home visits).
Simple way to test the tweeters removed both jumpers and run you amp to the top biding post red and black positive / negative and do the same LF red and black to test the woofers
