What does "blown spearker" mean?
I've been reading about a car like mine and the owner says that the rear
subwoofer is "blown". I always took that to refer to an electrical open. Does that ever happen? But does it also refer to a torn surround? |

But does it also refer to a torn surround? Typically a "blown" speaker can mean that either the voice coil is open or that the surround is torn which will result in distorted sound. Either can be fixed, it is just a matter of how much the cost will be. If the surround is torn, it can be easily replaced. While the coil can also be replaced, it is a much more involved task that requires some finesse. These days, consumer speakers found in cars are usually replaced rather than repaired as that option is cheaper. Dan |

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".. |

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! |

Please check that it didn't say "blown away" which is something quite different. But does it also refer to a torn surround? Torn surround, surroundings, or both? http://main.iosmars.com/wp-content/uploads/2014/10/image1.jpg -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
