    Thanks for the great vid! I really needed the explanation of the “sweet spot” as I’m about to do a pair of Baby Advent II’s that need new foams. Your vid has been the only one that really explained the reasons to take time, be patient, and make sure the clearance is perfect. Thanks!

    I just watched this video on speaker repair and have enough confidence now to re-rubber my 8 inch speakers from my stereo console. I went to the Springfield speaker website but they are asking me for make and model for my speaker, but it has no markings on it. What do I do by the way I find your videos to be very informative and easy to follow. You don’t spend all of the time with useless chitchat, you’ve helped me quite a bit working on Stereo Console’s. Thank you.

    The first time I did this, I just put the glue on the cone and the frame and set the surround on there. The glue was sort of a mess, but it totally worked, which was good because this was for a customer. Luckily, the woofer mounted from the inside behind a fixed front grill, so my sloppy job couldn’t be seen.

    My dad has a pair of Rogers LS8a speakers, but the surround has deteriorated (more like powderised). It appears I will have to do a DIY repair to refoam the surround of 4 drivers (which are 6.5 inches / 165 mm each). Can I seek guidance on:
    1) where I can buy good quality surround foam and the glue for the repair work;
    2) the type or material of the surround I should buy for these speakers (I believe it's the foam type instead of the rubber type). The concern is if I use the wrong type it may affect the sound of the speakers; and
    3) I believe do not need to refoam the tweeters (sorry if this is a naive question), hence seeking confirmation on this.
    I reside in Malaysia. Thank you in advance or any guidance provided.

    Pardon my ignorance on speaker basics - would like a tiny direction for my problem. I bought a 8inch 50 watt woofer (not sub woofer) about 15 years back, used it for few hours and it sounded good. I opened it today and connected it to my amplifier and it outputs too little volume. I gently pushed the cone and spider up, and the volume goes up and it vibrates well. How can I fix it? The spider feels hard... the soft rubber on the outer edge of the cone is soft/flexible...

    Thinking of refoaming a set of BA A60 speakers. If I mess it up will a pro be able to fix it? the cabs for these speakers are a bit damaged so they aren't worth as much for reselling if I no longer need them but for my personal use as a spare stereo setup they should be fine. However I am a little concerned about the whole "voice coil rub" issue. I don't really know what speaker rub sounds like. Maybe it will be evident if I mess it up though. Can the foam be easily taken off by a pro for refoaming if I mess it up?

    • @JordanPier

      Ok, in that case you can use the pro grade black adhesive that Springfield speaker repair sells. Works well and sticks to anything.
      I usually just carefully scrape away the old glue with an exacto knife.
      Make sure you keep the voice coil centered while the glue sets. Otherwise the voice coil will rub and eventually short out against the magnet.
      If you can forgo cosmetic concerns and you're not good at kinesthetic memory, you can cut about 90% of the dust cap away and install 3 shims 120 degrees apart. I will use camera film with the feeds cut off and about 2" long. About 3 laminations worth should keep it centered.

      @@JordanPier Thank you! The suspension seems to be doing a good job of keeping them centered. If I press the center they move without scraping. My thought for pulling the cone away from the surround to apply glue, then pushing it back into place to adhere is to apply a few volts to it then reverse the polarity. I *think* that should pull/push the cone evenly and help keep it centered...? I'll test that theory before I start gluing, unless you have a better idea. I'm not too concerned with keeping them pretty, but these have a hard plastic dished dust cover so cutting them without causing damage seems like it would be difficult.

      No it's an arbitrary measurement. 5"/6"/8" speakers can have different overall measurements and vary considerably in size. The measurements you'll need for foam/rubber surrounds are the outermost diameter of the surround where it's glued to the basket, the diameter of the outer roll, the cone diameter and the inner diameter of the surround where it's glued to the cone.

    Not a bad job, but there are some errors. First you scraped the cone at an angle. You don't want to do that as you risk slicing into the cone and damaging it. The foam doesn't take much effort to scrape off. You also don't need to be that rough. Keep your blade vertical 90 degrees, and scratch at the foam. For cleaning the basket, give the OD a brief soak with acetone before you scrape the foam. You also risked jabbing your hand the way you were scraping the basket. You use the correct technique, which is to apply the glue to the ID of the edge, not the cone. You did that correct, but your glue bead was too thin. Don't be afraid to go glue heavy so that a symetrical bond is true, and there is no chance of any part of the foam flaps when you crank the bass. You also don't want the foam to separate later. So go glue heavy. When I was training a coner once, he had 4 returns in two weeks. He got lazy. 1 was foam separation from weak gluing, and three were from flapping sounds when the woofer was cranked up because the bound wasn't symetrical.
    Its hard to assure a proper coil alignment without a signal generator, however not a bad job for the first time.

    After having done over 20 sets of speakers myself, I have several questions and comments:
    - Can you really get all the old glue off the cone simply by scraping? Shouldn't the new
    surround be glued entirely to the cone material with no old glue remaining?
    - How do the various combinations of old/new glue work or fail?
    The sample in your video after scraping looks nearly identical to the Genesis woofers
    I just scraped myself, but with a fair amount of glue remaining. I can "tease" it off
    with needle nose tweezers, but it's very tedious. I had to do that with a set of
    Epicure Fives. They had so much old glue that I initially mis-measured the cones
    for replacement surrounds. After looking closer I realized that a full 1/8" of the
    cones "edge" was old glue. I had to gently pry it all off with said tweezers.
    I've encountered multiple formulations of old glue, some so brittle that it indeed
    scraped off, others still fully tacky and flexible. I can't easily remove it without
    isopropyl alcohol. I gently pried off and tested some samples of this typical stuff
    from a pair of Genesis woofers and the alcohol is the only solvent that dissolved it,
    albiet slowly. Mineral spirits, Goo Gone and naptha had no effect.
    - When gluing the new surround on, don't you have to have 100% surface contact to avoid
    "flapping" at high volumes/cone excursion? I've been using the "clear" glue from
    Simply Speaker with good results, making sure I press the edge so I can see glue
    seeping out just a bit.
    - I always let the glue on the cone set overnight before doing the rim.
    - What's your opinion of the white glue? I tried it on a few drivers and it works, but
    takes forever to set.
    - I've never had to remove the dust cap and use shims. I use the mini-clamp signal
    centering method. The only time that didn't work was on a defective driver where the
    spider itself was off center and large excursions had rubbing.
    Much thanks for any input you have on these talking points!
