I thought I’d share this little tweak I did a couple of days ago.
My speakers are active and each contain a Toroidal transformer. The left speaker in particular had developed a mechanical hum that was audible if the room was quiet, so I decided to open them up with the intention of removing the transformer and putting some rubber sheet between it and the chassis.
Once I got the backs off the speakers I could see there were already rubber discs under and on top of the transformers. I tightened the transformers, the left speakers transformer being a little loose.
I then cut a strip of car audio sound deadening mat to wrap around the transformer.
Been thinking of similar for my kit but lacking the bravery
Maybe I could try out on my other systems.....
I’m quite impressed by the improvements in sound, but I wouldn’t use this sound deadening Mat on anything your likely to sell or that has warranty left. It’s incredibly sticky and probably won’t come off too easily.
