[QUOTE="geolemon, post: 318646, member: 547749"] If you push down on one side of the cone, you'll askew the cone in a very unnatural way. You ESPECIALLY shouldn't push anywhere on your cones while they are in operation, because you could "rock" the cone assembly causing it to strike or rub the side of the pole piece, or the side of the gap. REALLY bad idea. [IMG]//content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif[/IMG] Of course, if you push down on one side of the cone, you'll tip it that way, and you'll potentially cause the former to rub on something that it shouldn't. That's not a bad sign... That's an "of course".

The cheap and effective homemade solution for this is to just glue a small layer of felt (similar to what's glued to your cone) to the outer roll of the spider, just below the leads.
