I've been reading about a car like mine and the owner says that the rear

But does it also refer to a torn surround?

Any kind of failure falls under the description of "blown".

Open, intermittent, shorted, or melted/shifted voice coil or weak or damaged surrounds all fit that description.

"Blown" has become a catch-all for *any* kind of failure, even medical: "I blew my back out swing a bat. I won't be able to play for several days"..


Thanks, you, dan, and phil. I guess I have to update my view of the
word.

I can't remember if I got back to you about this:

Toyota Solara convertible, when they were still made, used a woofer
behind the front seat. The paper surround had fallen apart and after
discussing it here, I replaced it with one from SimplySpeakers. It was
very easy. Their instructions don't require centering the cone, except
iirc by pushing it down and up, or up and down, once.

And the glue they provided was very good. Like Duco Cement from the
60's but better.

So the speaker goes in and works fine, but now there is too much bass. I
turned down the bass, but I could still hear it even during talk shows
like Terry Gross and the news. Other things broke and I got a new car
but I think the reason mine had had one of the voice coil wires cut was
to cut down the bass, and when that wasn't enough they unplugged the
whole thing. I repaired the cut wire and now I sort of regret that!
