Hi all,

this short article, by yours truly, sets out to debunk the many absurd
myths surrounding sudden failures of loudspeakers - particularly
woofers used in live music and disco sound systems.

The article is rather tightly written, so you may need to read it a bit
at a time and cogitate.

Take a careful look at the links provided at the end of the article too.

And before anyone asks, the 40mm voice coil and magnet gap are from a 10
inch woofer used in a very old AR2a.

The pics shown in the article were taken by me with a pocket size Cannon
A430.

Great summary, Phil, thanks for posting. And, thanks Rod, for the
site!
