I have been running these for about 4 months now. I fired up the system (no music plating yet) this morning while I was dusting and noticed a hiss/static from one of the rear firing Emit K tweeters. I checked the remaining 3 and they all have some hiss/static. One has a louder hiss/static than the other 3. The other 3 seem to be the same. I increased the volume (without any music playing) and it did not increase the static/hiss. Also, the adjustments on the back did not make any difference regarding the static. The one with the loudest static, I can hear standing about 2 feet away, the other 3 about a foot away. The all work when playing music. No other drivers have this issue. I'm going to guess this isn't normal for Emit K's. Has anybody here experienced this issue? Any ideas on where to focus to fix?
I'm driving these with my MC2200 and C28.
Thanks for the help.

I have, so far in my long journey with Infinity Emits, and for the last couple a decades, Emims, have to say,
if the tweeter itself is not failing or failed by crossed pathways, the sounds you describe have always been explained in my systems by failures somwhere else in the chain, that the Emit is just reproducing what it's fed.
Just this last week, after getting my RS 2b set up, I discovered a new source of distortion, interefeirence audible (to my ears,with the new Infinity's, but had been present recently occasionally, causing me to wonder if something was wrong with my Maggies)made me start searching
I chased this particular gremlin pretty deep before I found it.
First off, I checked that the distortion was present with other sources (chromecast audio, chromecast, fully balanced connection from my audio server in the bedroom,) or that the distortion was or wasn't there with the seconday amplification system I've got set up in parallel, (dayton 94 something 100 wpc chipamp) and only when I was able to isolate it to the media computer, through three different audio outputs( usb dac, balanced audio outputs, hdmi audio output) and when I could hear it on all of them, and not from any ohter source, I knew i had to tear the chain down and find the flaw.
The power cord (standard upc three prong cord) of the htpc computer had pulled out a little over halfway from the power supply it was being fed from.
Usually it ( audible distortion) has been amplifier circuit failure, pre-amp circuit failure, etc etc
This time it was distorion being added into the exposed prongs as rf frequencies, it was odd how it created a 'warbling' distortion from the emits/emims, and also from the maggies true ribbon right before I swapped the new infinitys in.
This has been a major reason why I've gone to a reputable power conditioner, and had to rehab most of my carver amps, because with infinity speakers, and maggie speakers, I could hear distortions in the original signal to a level I never though possible before.
iow or tl;dr check and double check your entire signal path before you point blame at the emits, they're likely just 'giving you' what they're fed.
