Fixing a subwoofer?

Question

our subwoofer has ripped. is it possible to tape it for the same effect or do you need to purchase another?

Answer 1

When you say ripped, I assume you mean the cone structure and not the surrournd, correct?  If so, you can fix this by using a SMALL amount of a paper towel and some white glue if it is a paper cone.  Use the paper towel as a backing for the rip and the glue to hold it together.  If it is a polyproplyene or a plastic cone of sorts, then use some epoxy instead of white glue.  But, use just enough to cover the rip and hold it together.  If you use more, you will change the mass of the cone and then the sound will be off.

If it is the surround that ripped, then you can have a new one installed, or you can patch the rip with the sticky part of a plastic bandaid.  Cut the adhesive part from the gauze and use it to cover the rip. Make sure you overlap it and if the rip is actually a hole, then you need to put some on the back so the adhesive is covered.  

Both of these methods work quite well - I have used them on speakers costing upwards of $27,000 without a hitch.

Answer 2

You could use white glue. Apply as little as possible. This may somewhat change the quality of its sound.

Hopefully it's not so damaged that will run off-center in the magnet's gap.
