Loudspeakers haven't really changed much in in their basic build in well over a hundred years now, but they have evolved to become much more robust than ever.
Here's an interesting video that shows just what's needed to pop a massive 21 inch Pyle woofer (it's not easy even with 2000 watts of power). There's also an interesting tear-down at the end where you the entire speaker taken apart, even the magnets.
You've blown a speaker and it's expensive to replace, or maybe even not available any more. What to do? An alternative is having the speaker reconed by a professional or even doing it yourself.
Most major speaker manufacturers supply recone kits for their speakers, but there's a technique on how to do it that you have to know before you begin.
Here's a great video that not only shows how a JBL 2226 woofer is reconed, but gives you a great inside look at the different speaker parts as well.
If you want to try recone a speaker yourself, you can get the replacement parts from simplyspeakers.com, who made the video below.
