Well there is no voice coil rub but once the cone start to reach the point where the surround starts to crinkle then thats when i hear the noise. it sounds like the tinsel wires are hitting the back side of the cone but there not. The noise is deffinitely coming from the cone. what could be the prob?</p></blockquote><p></p>
