“Good Afternoon,
I was not able to hear the sound in the recordings. Again, my concern is that there is no issue with the drivers themselves, and you may be hearing something picking up vibrations in the room, possibly on or within your entertainment stand. When there are issues of distortion in speakers you will not hear it only part of the time. I am very happy to work toward a solution with you, but so far there has been no clear indication that the speaker is in any way defective. Also, we have had no reported manufacturing defects associated with this speaker that I am aware of.
Again, I would like to assure you that I am taking your complaint seriously and trying to consider what might be the cause of the sound you are hearing. Would you be able to send me pictures of the speaker with the grilles off--specifically some images of each driver?
Best Regards,
Technical Services Agent”
My reply:
“Nothing is vibrating in sympathy. Standing in front of each speaker makes it very clear each is making this sound. I’ll try recording again. I reserve all rights.
The right speaker is first shown. You will see small scratches on the trim ring done while switching the uni q.
Again, this is NOT created by anything in the room. It is the Uni q drivers, and I’ll not be keeping them even if KEF abandons me. It is unacceptable. “
Looks like I’m SOL
