Help with kef r900 issue

I have only a wife, who hears it, too. When I play one channel, it is in the center of the speaker. Playing both channels, it is more or less centered between them. A sympathetic vibration would not appear to move, but would be an unmoving point source. 

Try to change to upmarket power chords cables sometimes it can make the sounds better and smoother.Because you have this disturbance on both speakers I assume that there is some misfit between your system to the speakers that can be solve.
I am pretty sure that if Kef have had problems with this specific model they would be aware of it and change your speakers immediately.

Please go back and read for content, and your response otherwise begs the question. The new cables and interconnects are from Transparent and Cardas, and are system wide.

Your assumption is mistaken as the condition remained after all cabling was replaced.

I’d be most appreciative if you would not further confuse matters.

Again:

1. The condition persisted after changing McIntosh gear to Rotel-the sound is identical;

2. The identical condition persisted after changing all cabling from the speakers and interconnects to Cardas or upgraded Transparent; and,

3. The condition appears to emanate from inside a speaker if one is used, and between them if played in stereo, something a point source, sympathetic vibration will not do.

This appears to mean the most likely competing inferences are:

1. The condition exists in both speakers under limited circumstances, either from a design or fabrication defect;

2. There is a latent room or other condition that results in a sympathetic vibration that appears to move from speaker to,speaker when one is used, or remains fixed between them when stereo is used; and,

3. The condition is subjective and shared between two people married 42 years.

I have only an IPhone and IPad to record it, though I believe I have, and KEF claims I have not.

I opine the condition exists, that it is likely a design or fabrication issue since it exists in both, and that it is not a peripatetic sympathetic vibration.

“Good Afternoon,
Since I am unable to hear the issue you are reporting in the recordings you have provided, I would suggest sending the speakers back to us for testing. If we should determine that there is any defect in the speakers we will have them repaired under warranty. Please follow the instructions below to send your speakers back for testing, and if needed, repair.

Please pack your speakers securely, with all original accessories, in the original box if you still have it, and send to the following via UPS:

Please take all steps to ensure that the speakers will not move within the box, and that sufficient packing is added to secure the speakers from external damage as well. KEF will not be responsible for damages caused by shipping and damaged packages may be refused.

Well, there it is, I’m in the Pacific Nortwest. So, it will cost me about Three hundred dollars just in freight, probably the same or more to get them packaged, and I’ll have no music for an indefinite time. I’ll never do business with KEF again, and the Doc was right, buy direct and you may be buying a problem with no practical solution. 

I’ll try to sell these locally and move on. I appreciate the comments of those who truly tried to help.
