Is There a Way to Lessen Vibration On Cables From Powered Speakers

Custard.

Buy some long troughs and make up thick custard to put in.  Add a heating element to keep the custard nice and warm.  Make sure the cables are suspended so they are covered by the custard but not sitting on the bottom or sides of the troughs.

@gaukus you have treated the symptom but no solved the problem. Thats cool but it still doesnt mean you solved the vibration issue. Is the plate amp a class d or a/b? The reason I ask is if its a class d and getting hot enough to melt putty….you must play louder than most.

@ghasley

It’s a class a/b push pull amp.

In about two years I will upgrade to their HD6 speaker system, so for now, getting inside the plate might be a step too far for me. I have thought about cutting some strips of Neoprene and placing them along the inside of the amp’s internal ridge where the screws go, but I am not confident that it will work.

Without opening it, I surmise the issue will be whatever harness or frame the speaker drivers are attached to. The drivers are obviously the source of vibration. So the harness they are attached to is not decoupling the vibration. If I add material to that, there is a strong chance of harming the actual acoustics of the speakers, which I do happen to like.

In my mind, I have formulated a much better solution to the symptom. Two pieces of heavy steel, with Neoprene on one side of each. Then sandwich the cable. The blocks shouldn’t need to be more than 3 or 4 inches in width. I say that because, adding a little of the rubber and gripping it hard, also stopped the vibration. So one needs pressure, but spread across a larger area than zip ties were offering.

Congrats then @gaukus youve achieved your desired result.

ANOTHER UPDATE:

Well, I may have solved the cable vibration, but in doing so, I smeared the holographic dynamics of the sound.

So either the Neoprene Rubber was acting as a signal dampener or bundling interconnects and speaker cable so close together under a blanket interacted with the cable's geometry.

So, for now, I have uncovered them. I need to research more about the properties of Neoprene and see if covering each individual cable is a better solution.
