arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Here is a picture of the woofer that as you can see is in sad shape. The foam is shot and falling apart. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 First I took the woofer out, 6 screws hold it in place. I turned it over and began the process of taking off the outside trim ring, it is held by a few little plastic things that screw onto some small studs on the trim ring. I counldnt find my needle nose pliers so I grabed what was handy a set of channel locks a little to big for the job but they worked. I got the plastic holders off and then began to use a utility knife to remove the glue that also holds it in place. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Here is a picture of me cussing and getting the glue off of the trim ring it was like cutting concret with a razor blade some real tuff glue they used. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 well once I got the glue broke loose I then turned the woofer over and took a screwdriver and poped the trim ring off. I bet it took me 15 minutes to get this thing off because of that hard glue. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Next came removeing the gaskets, I took my utility knife and got underneath them and removed them. I needed to be carefull and not tear them because they need to be reused, new ones did not come with my refoam kit. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Here is what it looks like with the gaskets removed, what a mess to have to scrape off. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Here I used a razor blade to get off the glue and left over foam. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 I then fliped over the woofer to clean the underneith were the new foam will go. This is some sticky stuff make sure you have plenty of newspaper around if doing this its like tar. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 After I got most of the foam off with my finger I then used a small screwdriver to get the tar like glue off of the speaker. I never could get all of it off but it wont matter the glue and new foam will stick to it. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Time to remove the dustcap for shimming the voice coil. I cut it into little pieces as the picture shows be carefull not to cut the woofer if doing this. It is a must to have one of these small hoby knives it worded like a charm.

arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 I then covered the voice coil area with some duck tape so I wouldnt get anymore stuff in there. This is some tricky cutting to do now there is still some of the edge of the dustcap on the speaker cone that needs to be removed. I carfully made about 3 pases around with my hobby knive and was good enough for me. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Here is a picture of me finished with the dustcap removall. Lots of stuff came off of the cone from the dustcap as you can see. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Time to shim the voice coil. The kit came with 3 different size shims that are about 3 inches by 6 inches and paper thin which I cut into 3 pieces to fit around the voice coil.I used the thickest shim and the medium thick shim this made a nice tite fit to hold the woofer straight and aligned for the refoaming job.

arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Time to start putting this woofer back together. I turned over the woofer and aplied the speaker glue that came with the kit to the area where the new foam will go. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Next I flipped the woofer over and then applied glue to the new surround and set it in place. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 After I got the foam suround in place I centered it the best I could and then used my fingers to press the foam suround around the speaker cone. It worked perty good the drier the glue got the better the foam stuck. The less glue you use the better off you are I found that out.

arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 After the glue dried for about a half an hour I then took a tooth pick with some glue on it and went around the foam. Probably not necesary but it will help seal and hold the foam suround to the cone. After this step that was done to both woofers they needed to set overnight to let the glue dry before glueing the foam suround to the woofer basket.

arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 Well now that the glue has dried overnight its time to mount the foam suround to the basket. I placed glue on the metal basket and underneith the foam suround. Quote Link to comment Share on other sites More sharing options...
arfz28 Posted January 28, 2005 Author Share Posted January 28, 2005 After I had the glue spread around the basket and underneith the foam I then got the gaskets and started glueing them and got them ready to put them into place. Quote Link to comment Share on other sites More sharing options...
