i am busy restoring my M10s, very old, Polk speakers. i have ordered, and received my new (i think) SL2000 Tweeters from Polk USA, and had a chance to put it in this weekend!!
Now, the new casing is different to the old one, and had to make some adjustments on the speaker box itself( make the hole slightly bigger...)
BIG PROBLEM!!!! because, without taking the mid-range (MW6500) speakers out of the box, it seems that the tapping and hitting( im assuming the shock..) on the box, have done something to the MW6500s. they are SOOOOO hard, and stiff, they dont allow any movement!! WHAT HAVE I DONE, AND HOW DO I FIX THIS!!!! the boxes were not connected (obviously..) but for some reason, when i put the box on its back, and tapped it, the speakers went crazy!!!!! now all four (two per box) are pretty useless,(i hope not anyway!!) its as if the coil isnt in the magnet, but it is SO stiff, that even almost with force, it doesnt want to move!!
PLEASE TELL ME IT HAS HAPPENED TO SOMEONE ELSE AND SOMEBODY CAN HELP ME!!!!!
