AR5 tweeter problems.

No, no, no, no, no!

If you GENTLY push the cone in and out trying to keep it even (don't push in one spot) is there a rubbing sound? If so, the coil has distorted or turns have come off. Repair or replace.

Do you mean holes in the suspension? If so, how big? Small holes are harmless.

To see if this is the problem, push at the edge of the voice coil (not the edge of the cone), move round pushing at each spot. If this slight offcentredness causes grating/rubbing, either the voice coil has partially come loose or the cone needs recentering. The need for offcentred pushing is that the paper structure will bend during use, so pushing it centredly may fail to show up an existent problem.

Either way you'd need to remove the paper cone from the tweeter frame. Carefully. Recentering something as smsll as a tweeter should be fun. Its doable but not easy. Rewinding a voice coil is straightforward enough if you can get the old wire off, but a sod if its stuck solid - as it should be.
