Sound restoration part II
I stayed up to finish one more item on the LX. I got the foam kit in the mail today.

Since I had already prepped the speaker ahead of time by removing the old surround and creating a clean cone and fame edge to glue the new one too, this went pretty quick. The prep is what takes the longest.
First, make sure the new surround is the right size by doing a dry fit. Make note of the inside edge so you don't apply glue too far into the cone where the foam will not cover it.

Start off by applying a good even bead of glue around the outside edge of the cone.

Apply the new surround to the glue making sure it is centered and even. Start out applying light pressure to set the glue once it is oriented correctly. Work your way around the cone using two hands working opposite of each other. If you try to slide your finger around the edge it will cause the foam to stretch and make it uneven, creating lumps.. so don't do that. I continue to press it into place working my way back and forth around the cone, with two hands, for a couple of minutes.

After about an hour the glue is bonded good enough to start on the outside edge. I prop the cone up and away from the frame by gently putting paper towels between the cone and the frame. This gives you room to apply the glue to the frame without the foam falling into place until you are ready.

Apply a good even bead of glue to the lip of the frame. Remove the paper towels and allow the cone to fall into place. Lightly push up and down on the center of the cone a few times to center the voice coils. You will feel slight grinding when not centered and it will move up and down smoothly when it is centered. Once centered, start working your way around the edge, with two hands, pressing the foam to the frame and setting the glue.

Do this for a few minutes. Then put a bead of glue on top of the outside edge of the foam and put the plastic speaker edge back on. Flip the speaker over, apply a little pressure, then let it sit and the weight of the magnet will help hold things in place until the glue is completely dry.

It came out good. I will see how it sounds tomorrow.
Old and busted.

New Hottness!
