question

question about my 2 L7's i thought were blown. i was gonna sell these to blunt for use in his little project. but i decided to test the subs using a 12volt source (cordless drill battery). i tested both woofers and on one of them, the cone slightly moves, but it makes a "slinky" sound so i'm pretty sure it's gone.

the second woofer, i tested it and the cone moves in and out still and if i move the ends of the wires up and down the terminals on the battery, i can hear the scratching perfectly through the woofer. don't hear any "slinky" sound, and it still moves. am i led to believe that it still works or can blown subs' cones still move some?

nvm. tested the coils via dmm. one woofer seems to still be in somewhat working order. gonna go test it out now.
