having recently purchasing a JBL 518S subwoofer from a friend I am now experiencing a vibrating sound. It was fine set it up at a mates tested it out worked well very well even. Then set it up at a wedding I had on and still fine. Not until I got home 2 days later and set it back up I am now hearing a vibrating noise coming from the sub. I have pulled the grill off to make sure there was no tear or damage to the cone which looks fine. So it makes this noise more noticeable at low levels, if you turn it up i guess it gets drowned out. The noise will stop if I apply pressure to the cone say anywhere between say 5pm & 9pm on the inside of the outside edge it will stop. I hope this isnt ruined please someone know what is going on and have a fix! Thanks in advance.
