Don't know what has happened - all is big big guess ... who knows??

Lets us guess - maybe you ran the system too hard or too loud and got the voice coils hot -
maybe melted the varnish on the coils - maybe the coils are sticking now because of the bubbled varnish when you try to play them?
Again, do not know absolute - all I can do is guess from far away place ... maybe help, maybe not ...

Maybe you have too much fun last few days?

Sounds like you need to take them to a speaker shop and
have them do testing - I cannot test for you from here in Virginia ...

So sorry, best wishes!

If those are old cones there may have been some sag in the suspension from being left in the same position for years. The materials have something of a memory, so there may have been just enough correction during the time they were dismounted to clear the voice coil, but when left overnight mounted, possibly in the same position they were in before (we all like those little leads pointing downward), they resumed their sagged position after a few hours. May be time for a recone. Just speculation, of course.

One thing is sure. With these woofers it is not possible to get the voice coil outside of the magnet. They are ... Don,t know the English word, but the magnet vs the voice coil the magnet is deeper.

BUT, what happens if the speaker cone is to old, I really don't know. Some of you experts on this should climb in.

Is the foam around the woofer rotten? easy to peel off? if so they just need a re-cone.

Did you physically test the voice coils before you installed them? I bought a pair of LE15s a few months ago that had been listed on EBay as perfect but the coils rubbed when they arrived. I offered to split the cost of a recone with the seller because they were still a good deal but he opted to refund me. They were relisted within a few days and sold as is with no mention of the rubbing coils. If they came from Victorville, CA it might have been you.
