In most cases when a speaker isn't working properly you would think the speaker needs to be replaced. However that's not always the case, most the time you can actually repair the speaker for a significant amount cheaper. Don't be afraid to investigate the problem! This particular sub froze up after the owner hit a big bump while driving his car.
I first separated the rubber "surround" from the "basket"
I then separated the "spider" from the "basket".
Next I removed the bolts holding the "terminals" to the "basket".
After that the "cone" "spider" and "voice coil" was able to be pulled free.
Revealing the problem! The "pole" is pinched against the "top plate" not allowing the proper movement of the "voice coil"
After taking a closer look I noticed the "magnet" had actually broken free from the "top plate" all I needed to do was glue them back together! In order to get the "pole" positioned dead center I used thin wooden shims. I first placed the wooden shims between the "pole" and the "magnet", after applying a thin layer of JB Weld I then slowly lowered the "basket" that still had the "top plate" attached to it onto the "magnet". Be very careful when disassembling and reassembling the speaker, in most cases they use very strong magnets and anything caught between them will be damaged! Including fingers. I set a wight on top of the basket and waited for the glue to fully set. Once that was done, I glued the " spider and rubber "surround" back into place and reconnected the "terminals" to the "basket". Done and done! This repair cost $5 in materials, replacing the sub would have ran about $200. Not bad! Any questions let me know, if you need speaker repair parts or the glue check out this sight.
