My Klipsch Promedia v.2-400 subwoofer box is rattling with heavy bass audio. It did not do this before. I checked the actual subwoofer cones and they are in still great condition, no tears or signs of damage. I tried testing the sub with heavy bass music with the amp out of the box and the rattle stopped. I even took it a bit further. I tested it again with bass heavy music, but this time I lifted the amp with my hands and had it just sit on my fingertips on one side while the other side rested on the box. I basically used my fingertips as supports for the amp. This also resulted in no rattle and vibration with the bass heavy music. So just based off this observation and testing, I have come to conclude that the amp is rattling against the box when there is heavy bass present.
I had some cheap foam laying around that came from my PC motherboard packaging and used it to cut up strips of foam. I laid it around the edges of the amp where the old foam insulator is (which looks very worn down). I tested it again and it did not make a difference at all and the rattle is still present. Is this because I used cheap foam that wasn't designed to dampen and eliminate vibrations or is there another culprit for the problem? I'd like to think the former, but I just want to make sure before I start buying real isolation foam that is designed for this purpose. It looks kind of pricey based off a quick search. Anyone know of good cheap alternatives that serve the same purpose?
I'm a total beginner when it comes to this stuff so please excuse my ignorance.
