  • In this video, I am repairing a Genesis 12" subwoofer driver. I bought a foam replacement kit from speakerworks.com, and the process of installing it went very smoothly.
    The song is One Less Worry by Dennis Chambers and Niacin. It's off the Drum Nation Volume Two album.

    Thanks for sharing. I just inherited a set of vintage Fisher XP-65s speakers and the 10" woofers are in desperate need of new foam surrounds. Great tutorial.

    Shimming the voicecoil may be a good idea, however this speaker has been used every weekend since this video was made (over 2 years ago), and still sounds great, so I'd consider my repair a success.

    Cool vid. Going to be doing this myself in a few. Didn't think about using a brush. Looks like it made the adhesive process neater than expected.

    a tip I'd wish to give to the viewers of this video:
    Elmer's Rubber Cement is a great preventative buff to put over a weak cone/suspension.
    If the hole is too big, I sometimes use paper towel dipped in rubber cement to patch it up.
    Sure, it adds a little extra mechanical resistance to the speaker, but I can't hear a difference nor have I ever damaged a voice-coil by making it too restrictive.
    And like always, thanks for the great videos

    Dude, now that I've found this video, you are officially my favorite subscription! I wish I could do projects like yours, like messing with arc lamps, DIY aerogel, all that good stuff. Also, I have (I don't know why) a strange passion for loud bass. The powerful thump of a massive car stereo makes just me feel really happy. Seeing you working with a subwoofer on your channel is an instant favorite! BTW, you should really look up what multi-kilowatt subwoofers can do to their car : ).

    Just bought a pair of Duntech tower speakers from Australia yesterday. They were 10 Gs when the came out in the 80s,I got them for 1,300 . Anyhow after playing a few records very loud the surrounds went,all 4 of them. Im just wondering if I should do this myself or get an experienced repair person to do them. I cant even find a place in town that sells the surrounds,and Im wondering how important it is to get the original brand for them. Any advice is much appreciated !

    Ok stupid questions. Does the surrounds on the speaker have any effect on the sound quality? I am trying to repair an old 1991 sony ss-tl1 speaker and the surround foams on the sub woofer are gone. The bass without the surround foam is very lacking. Will it change once I add the surrounds? Or did i ruin the sub woofer when I used it without the surrounds

    Your misunderstood. Your dual speaker connections are for your dual speaker coils. You have a DVC speaker and ther nothing to do with feedback. Instead it has everything to do with speaker wiring. If your speaker is a 4 ohm DVC speaker if you wire the 2 coils together in parallel then the 2 wires going to your amp is 2 ohms.

      The dust seal (spider) at the base of the speaker cone, where the voice coil is, keeps the cone centered. Also, gluing the surround to the cone first allows you to center the cone to the basket later.

  • @sweetsweatyfeet
    @sweetsweatyfeet 11 років тому

    The measured specs are altered only very minor since the flexibility coefficient of most foam surrounds is similar to rubber. Fs, Q and VAS specs are mostly affected by the speaker's spider (the surround itself having less of an effect). Usually rubber surrounds are an improvement in sound particularly in the bass and especially if they are made of butyl.

      The only reason not to use foam is because the sub is very active, like sundown where it moves an inch. If you use foam there it will tear. Foam is more mobile and you get a much richer sound. Unfortunately, it degrades much quicker

    Anyone who understands this is faulty advice would remove this video.
    Why not remove it? Asked of the OP.
    Well somehow, it is making them money?
    Then, of course, the reason is ... caaChing.
    Shimming, or running an audio signal through the voice coil during the gluing process is an accepted method for centering the voice coil.
    11 Years ago, maybe it wasn't known, but now it is.
    Any other method is based on luck, not science.
    OK, this speaker renovation lucked out, granted.
    But, this hap-hazard method, as presented, is not based on better, now common methods.
    I'm peeved this showed up in my UA-cam suggested files.
    The internet does not need more bad advice
    Get up to speed and remove what is aged, now shown to be wrong, advice.
