Have A Dented Dome On Your Cone?

Here's an old trick I learned from an old man, my dad.

If you have a dented dome in a speaker, that isn't rippled or severely crushed, you can pull it out with a piece of duct tape, or similiar stickey substance.
Just another use for ductape. Just stick a piece down in the dent, pull out. Simple.

Most the time this works, as long as it hasn't creased and it's only slight.
Doesn't effect sound quality. (would take a trained ear for subs)

some of the domes are a pretty rigid material, also try a air compressor and blow air through the magnet vent, ive done this. you do have to be kind of carefull. even if the cap comes off, just glue it back on one you fixed it. they're glued on with epoxy anyways
