I have two 15 KEI speakers that yesterday stopped working. These were in a 2-15's with horn cabinet and I had a tape deck connected to a K-200 amp on low volume. The amp on occasion has done the popping and crackling thing in the past and when turning the unit off and then turning in on again has made the noise stop. Unfortunately, I was outside when I heard the noise and by the time I got to the amp, the speakers had stopped working but the crackling was still coming from the horn. I have noticed that the sound quality over the past couple of weeks has been sounding muddy.
I pulled the speakers and the cones are all intact; I did the 9 volt battery test and one of the speakers did make a clicking sound but the cone did not move; the other speaker did nothing. The magnets are the big square one's with the 3 screws. I tried to take it apart but didn't want to pull apart so decided I had better get some expert advice before making matters worse.
Is it possible for me to repairs these speakers or do I need to send them in for repairs and if so, does anyone know of anyone or company here in Iowa that could do it for me?
Appreciate any help offered.

I use Simply Speakers for my reconing supplies. I just finished 2 Jensen C12N's with the black voice coil cover and they got the parts and created a kit. Call them at 1-800-511-3343. They open at 10:00 AM EDT. I have reconed both Jensens and JBL's and all you need to do is take your time. They supply instructions but it is very generic. JBL supplies what is called a "drop in Kit". the entire voice coil, leads, spider and cone are pre-assembled and all you need to do is put in the supplied shim and glue all the edges and drop it in and let it dry. I find it's easier to build your own "drop in kit" with the parts supplied and then drop it in after the assembly is done. The Jensen kits were $40.00. I would think that speaker manufacturers would use common parts but the guys at Simply Speakers will need some info so have the speaker close by when you call, and a good measuring caliper would be in order to measure the voice coil. You can measure the magnet and gap with the guts removed. You might as well tear it apart and see what goes into it. Start by using a razor knife and cut the cone around the mounting perimeter and then around the voice coil cover. You can then see how the spider and voice coil are sitting and the height that the voice coil itself. I wish I had some pictures to add. Then cut the spider and remove the voice coil. Put some masking tape over the voice coil gap to keep debris out. You need to clean up all the remaining material from the raw frame. At this point you might as well dive in, you have nothing to lose.

Go on You Tube, they have quite a few videos. It isn't hard if you take your time. Also. be sure to order the adhesives from Simply Speakers. I forgot and it set me back a couple of days.

It is simple to recone a speaker and yes what goes bad if it doesn't work is the voice coil. You have to have a few hand tools and patients and time. There are great videos on You Tube that show exactly step by step on how to do it, I have my own way of doing it now as I watched a bucnh of them and took the best parts from all of them and used them to make the easiest, most efficient method for me to do it. Many companies can get you the parts, but are just as expensive as getting it done professionally, but I would rather do them myself as you don't know if they had some young kid do them or an experienced Tech to them. I will do it myself so I know what I have when i am done.
