Replacing The Surround on Original Infinity Modulus Subwoofer
I'll be replacing the surround on this Modulus subwoofer shortly.
Before I do so, I'd like opinions as to whether it will be necessary to remove the driver from the cabinet. Take a look: http://tinyurl.com/jphyl Unless I'm missing something, it looks like all I'll have to do is remove the *inner* gasket to reveal the complete surround. Does that sound correct? Any pointers would be most helpful as well. Thanks, A_C |

Take it out completely, if only so you can shim the voice coil properly. Yeah, I know, because the spider holds it in place, you don't really have to shim it. But you should. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

In order to shim the voice coil from the front, you'd have to cut off the paper or aluminum dust cap and then re-glue it after you've finished the job you're trying to do. You may be able to remove a screw-on metal cover at the rear and get access to the voice coil. Depends on the speaker. I've never done this job. I know it's supposed to be so simple that only a child can do it, but I just figured that speakers are put together with special alignment jigs, by people who know what they're doing, and that without them, no repair job will be as good as new. I'd think, though, that if this is your first time (probalby so, based on the questions you're asking) and you want to give it a try, your best shot would be to do as little damage as necessary. If you leave the speaker in the box, at least it will be held solidly while you're working on it. If you take it out, and then remove the rear cover, you'll have a pretty unstable hunk of metal on your bench. Of course, to hold it while you're working on the surround, you could set it back in the mounting hole after removing the rear cover and shimming the voice coil. |

You still should look around the back to make sure you did it right. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I wish I knew what you were talking about... (Shim? Spider? Waaah???) Anyhow, I managed to get it done while still in the cabinet. Check it out: Befo http://tinyurl.com/jphyl Naked: http://tinyurl.com/o4nam After: http://tinyurl.com/s4x9a Pretty neat job, if I don't say so myself. :-) A_C |

If not, you run the danger of the woofer blowing out under stress, due to the coil possibly not being centered in it's gap. You should run a sweep test on it (with an oscillator, slowly run the sub through it's intended frequency range up to it's rated power to listen for any possible anomalies). jak A_C |
