The unenlightened might say that hope is lost once a speaker is blown. In some cases, this is true, but there are also certain instances where repair might be a better option than replacing the whole thing.
You can fix cone tears with glue, tape, or a patch. But for best results, use both glue and a patch.
For example, one of the most common causes of a blown speaker is torn cone fabric (the papery speaker material that makes up the diaphragm). So, below, we’ll give you a repair guide on doing this and how to check for a broken voice coil. And for further reading, you can check out our resource that explains how to replace car speakers.
Don’t touch or push on the cone patch while it’s drying. This mistake can reopen the tear, and you’ll have to repeat the process.
