Hi,

Unfortunately, the left woofer's surround foam cushion on my Klipsch 4.1 Pro Media subwoofer has blown. I was wondering if there is an easy way to fix it. Any ideas?

NOTE: I was thinking of using some sort of silicione that you shoot in and it gets harder, like an insulator.

I am on a budget.

Thank you,
Marc
 
Hi

I have successfully repaired two mid range units by simply replacing the foam as follows;
1 clean the cone edge and the frame to remove all loose foam and clean away all the foam.
2 buy two pieces of foam lagger then the speaker size 1/8" or 3mm thich foam and cut a circle of foam. I cut a circle that was one and a half times wider than the width finally required to allow for later movement of the cone. I made the outside circle slightly larger than the frame and the inside circle slightly smaller than the cone.
3 I used a rubber solution to glue the circle in to place.
4 I found that gluing to the cone first was easier. I then glued to the frame last.

The good news is that the speakers work fine.

Hope this helps

If it's a little tear, latex adhesive and tissue paper will keep you going for a while, but long term, I agree, get it sorted professionally if you can't get the surround yourself. To do it properly, you have to remove the whole cone, shim the magnet/voice coil gap and reglue, otherwise fixing the new surround could pull the whole cone out of alignment.
