Repair your own speakers with our do-it-yourself foam surround replacement kits. 
 

I was just writing to say that the speaker repair kit I ordered from you was exactly what I needed.  I had actually been looking at new speakers online when I came across your site.  With the instructions and parts you included, my 14-year-old daughter and I successfully restored my old mid-80's floor speakers to their original sound.  Apparently listening to vinyl records through 12" woofers is still cool.  She and I are both proud of the fact that we got the old system working so well and we did it for only $24. 
Thanks,

The Problem

The Solution

Deteriorated foam surrounds is one of the major problems with home speakers. The foam starts to crack and break after about 8 to 10 years. Our repair kits allow you to remove the old foam surround and easily reattach a new one.   What's the correct procedure for doing this?   Download our instruction sheet (in PDF format).   Or you can order our 20 minute detailed instructional DVD below.

Some refoam kits skip over the part about shimming the cone in place.   Sometimes skipping that step works, sometimes it doesn't.   When it doesn't, you're left with a speaker with a voice coil that is rubbing the magnet structure, resulting in a distorted sound and a shortened life for your speaker.   Our instructions give you the necessary directions to properly shim the voice coil, just as the professionals do.    This extra step is not difficult and takes only a few extra minutes per speaker, and ensures your success every time!   

Before you order, please measure your old surround carefully.   The following diagram shows necessary measurements:

"A" is the outside diameter of the surround - to the very edge of the speaker gasket.  If the "A" dimension on our replacement surround is a little too large, you can trim off a little from the new surround with a scissors (perhaps 1/8").

"B" is the inside diameter of the surround - measured right across the center of the speaker.   This is a very important dimension, so measure carefully. 

"C" is the diameter of the dust cap.   You have some choice on the type and size of dust cap you choose.   Sometimes you may want to choose a dust cap that is slightly larger than your old one.   That's perfectly OK!   Never choose a dust cap that is smaller than the old one, however.

Look at how the old foam surround attached to the cone.   Some surrounds are glued to the cone on the angled edge, as shown to the left.   This is called an angle surround.
Other surrounds attach to the cone along a thin flat edge on the outside of the cone, as shown to the left.   The type of surround that attaches in this way is called a flat surround.
