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.

or test with a 1.5V battery (AA, D..)  and two leads ... much safer and easier :-)
Just touch wires to the terminals and listen for a click.
I'm baffled how this could have been overlooked, but hey.
If the tweeter are not functional you have:
1. miswired, or2. missing wires (2?  unlikely), or
3. destroyed from heat/power -- likely actually
remember that tweeters can take very little power/heat. if you play too loud too long, or worse, have extended clipping, they take the beating. And fail. Clipping = disproportional % of high frequency info.
Its why i have fuses. I kow many of you likely consider it abhorrent but i design and and have flaky stuff in my system all the time.

OP:
I gots to know:

Did you buy them new or used?
Did they always sound this way?
Does anyone else operate the system?

This sentence alone makes me think they are blown..

" amps i was looking at , keeping in mind that I want the Amp to have at least 300 watts / 8 ohms / 450-500 watts / 4 ohms"

jetset,

This might have already asked and answered, but do the 2’s have any kind of protection for the tweeters? Can you get to the crossover? And how hard is it to get to remove the terminal plate?

All the best.

You say that the center speaker is working fine. How about removing the tweeter from that speaker and connecting it to one of your Sofia’s to see if it works.
I’m in the middle of replacing the Vifa tweeters on the speakers in my second system now (Amrita Summits). After 20+ years one of them finally went so I figured I may as well replace them both. My center speaker (also Amrita) has the same tweeter (which was replaced a few years back) so I swapped them out to determine the tweeter was indeed the issue.
As for amps, from my experience the Wilson's are a bit on the bright side so I would think the Parasound or Levinson would be a nice fit.  If you have decent audio shops in your area I would bring some amps home to listen to and compare.
But you have to get those tweeters working first!

Amrita...now there's a name I haven't heard in forever. I recall that they used to advertise in TAS.
