Got a pair of Altec 604-16X today but much to my excitement of owning another pair of Altec speaker...I've noticed a crack of about 2" long on the HF magnet. I do not think this was inflicted during shipping as there was black gray paint painted over the crack.

My questions are.....Will this affect the HF response? I'm thinking of replacing the HF magnet assembly...Is this possible and how much work is involved?
