Step 7: Glue the gaskets. You can attach the gaskets as soon as you’re comfortable that the foam is placed properly. Take your glue and apply some to the underside of your gaskets, then make it even with the brush. Place the four gaskets between the metal edge of the housing and the rounded part of the foam. The goal here is that the gasket covers the flat edge of the foam, and the curved part of the foam is free to move.

Apply glue to the underside of the gaskets and smooth
Make sure no glue touches the “domed” part of the foam. The gaskets have notched areas where the mounting screws will go, so please observe them and make sure your mounting holes are visible. Once this is done, place your speaker upside down to apply pressure to the gaskets and wait at least 12 hours for the glue to cure (24 hours would be best).

Attach the gaskets and place upside down for pressure
Step 8: Re-assemble your speaker. Attach the leads from your speaker to the driver assembly and screw everything back into place. Go test it out and I’m sure you’ll find that the speaker sounds as good as new.
Even if you did a sloppy job with the glue, your speaker will probably sound as good as new. My home theater subwoofer is over 15 years old and has resumed its bass-shaking purpose in life. There is no distortion or any other auditory anomaly to indicate that repair was not a smart choice. For $15 I saved myself from purchasing a new $600 unit. If your cone is just damaged then you may need to purchase new drivers, but this is still favorable to buying entirely new speakers. By purchasing an inexpensive re-edge kit, you can salvage your existing home theater speakers instead of buying whole new equipment.
Now onto the next project: building a booby-trap to encage any infants that come within close proximity to my subwoofer.

Nice article. I'd recommend using a polyurethane glue, such as Elmer's http: http://www.amazon.com Elmers-Ultimate-Polyurethane-8-Ounces-P9416 dp B000MVOX3C. Available at almost every hardware store, Walmart, Home Depot, Lowe's, etc.
