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

Rubber bands do work they just break after awhile how do you get around that MC . 

Blu tack or more likely the gray map putty should be available at a goodoffice supply. Amazon has multiple blu tack options available.

Ordered, should be here tomorrow.

Can you give me some insight on where to apply and how much?

Is this applied externally?  Such as on the screw hole from the outside, then insert the screw.  Or is it internal, put the putty behind the plate and insert the screw?

The trick with rubber bands is that just like springs they have to be sized to the load. My first ones were whatever I grabbed from the kitchen drawer. Once I heard it work then I experimented to find the right thickness and tension. Nowhere near as hard as it seems. Just stretch the rubber band lay the cable on it see how it bounces. Just like a spring it works best if the cable is heavy enough to stretch the band, because otherwise if the band is too strong it doesn't isolate much. But not so heavy it stretches it too much, because then it won't work as well and probably break all the time anyway.  

Do it right tecknik they will last a very long time. Mine are going on a year or so. They are after all rubber bands so not gonna last forever but easy and dirt cheap to replace because they are after all rubber bands.

I would try the putty in steps. Again, think of it as installing a gasket or absorptive buffer. You describe the plate amp portion of the speaker as the part that is transferring the energy so start there. form/roll the putty into a very small diameter continuous piece and then place the putty between the cabinet and the plate amp and reinstall. The act of screwing down the screws should squeeze the putty into position. Then, see if that reduces the vibrations.

My recollection is only one speaker has the plate amp and the other simply receives the signal through speaker wire correct? Does the second speaker vibrate like the one with the plate amp? If so, then you are transferring energy in other areas as well. While you have it open, see if you can possibly tighten the drivers, some of those screws may have come loose over time.

The law of diminishing returns really kicks in when you are dealing with a $2-300 speaker. Additionally, it sounds like you are listening at very high volumes. There is a point where you are likely listening outside their intended volume range.

Best wishes.
