      Over a decade before even Mr. BA did this, I used silicone RTV and toilet tissue which was also imbued with the silicone to patch an edge. Whatever its sonic vices or virtues, at least it doesn't crackle or rustle or distort the intended frequency response too much at an edge. The exact optimal consistency of the patch would depend on where it is. A stiffer cone (as with PVA glue and writing paper) and a more flexible edge (as with RTV and tissue) may be a virtue, to retain as much of the original characteristics as practical.

    Excellent video Bob. I've been collecting and restoring vintage radios for over 45 years but I've never attempted speaker repairs other than minor ones. Now I can hardly wait to tackle my first speaker restoration as I have many in need of just that. Thank you.

    Sweet! I just finished restoring a 1951 Philco SB/FM/Phono and dropped a screwdriver end though the paper cone. All the pieces remained, was just torn. Glad I found this video. Couldn't have imagined the repair could be this easy.

    Thanks for the tips! Just fixed my 10" Techniques bass speakers using glue, money notes (paper, not cloth) & a touch of newspaper. Works perfectly at low to medium volume, with some slight distortion at high.
    It had a hole in it from when my brother tried to vaccum the speaker, which eventually ripped around a third of the speaker.

    Haven't read all the comments, but using old drier fabric softener sheets also work very well. Just be sure they are used enough that the fabric softener is pretty much exhausted. They have the toughness of fibers and work well with diluted glue.

    Comment for visibility. Best how to I've found.
    Had a pair of old JVC SK-303 and one of the woofers was lightly damaged. Getting a replacement (1 woofer) cost about the same amount as selling/buying a working pair of the same speakers. Did this and it works fine now which is win win since it ended up costing me < $5 to repair.

    @PrinceWesterburg 8 років тому

    I'm just repairing a speaker and I've found a stencil brush (made for tapping, a 1" paint brush would suffice) is great for getting the coffee filter in the features of the surface. A screwdriver is good too, an old one with rounded edges on the blade.
    Great video!

  • @bandersentv
    @bandersentv  12 років тому +5

    Keep in mind I'm referring to antique speakers like the one at the end of this video. It's from 1929. They didn't use crossover networks, or permanent magnets or tuned enclosures. You'll greatly diminish the value to collectors if you put a modern cone in there with a synthetic surround. Some reconers go so far so to create new paper cones from scratch and use chamois leather for the surround.

    I have used the same basic technique of PVA type white glue and patches - I've never needed a real big section and thought your method of creating a new one from the existing come was just great.
    I also found on some old speakers with rubberised surrounds liquid latex glue "Copydex" brand in the UK is also useful

  • @polkiju7

    Have you tried a speaker like that RCA with a modern source? I’m just curious how they compare sonically. I’ve heard some that have a startlingly realistic presence in the range of the human voice.

    • @bandersentv
      @bandersentv  5 років тому +2

      No, but I can tell you the old speaker form the 1920s has terrible frequency response. Something like 200-4,000 Hz. As you said, good for the human voice range and OK for AM radio with it's limited bandwidth. Another issue with this particular radio is they the speaker is about 5 feet off the floor and pointing straight up. That makes for an odd listen experience :)

    Have you ever seen a radio, etc, that had a speaker with that metal bell in the middle in a cabinet that had it front-firing instead of top-firing?... I was just thinking that maybe that bell is used in that configuration there in order to help disburse the sound more omni-directionally, since it is being projected upwards from the top of that tall cabinet... just a thought :-)

    I have a RCA 17K with a speaker that has some damage but fixable by your methods, I think. The problem might it is sagging to one side from sitting there doing nothing for a long time. Will this be a problem or just fix the cracks and let it go as is? I haven't even tried to power it up, it's in really bad shape. Did you try the kies air with your new wireless system?

  • @kwacz
    @kwacz Рік тому

    When you do this, how do you prevent the voice coil from rubbing. Sometimes the voicecoil rubs after repair i assume because one side is more flexable than the other.

    • @bandersentv
      @bandersentv  Рік тому

      Put think plastic shims in the voice coil slot before making repairs. That should help keep it centered while the glue dries.

  • @bandersentv
    @bandersentv  11 років тому +3

    Modern cones often don't fit vintage speakers. Plus there's a chance of damaging the voice coil.

  • @TerryMcKean
    @TerryMcKean 9 років тому

    I found your videos about the Westinghouse radio this speaker goes to...it's cool....also, Saran-wrap type plastic film would do nicely for the protection while transferring the cone ridges onto the coffee filter paper

  • @ashebiara10

    is there a diference in using the clear tacky glue instead of the one that you are using in your video ?? is the clear one suitable for this kind of application ??

  • @ashebiara10
    @ashebiara10 13 років тому

    @bandersentv
    then i guess it should be ok .. i just saw a bottle of clear tacky glue in my mom's sewing desk and i don't see much diference so i will give it a try and see how it turns out .. the only thing that worries me is that the material of the cone seems to be much harder that the one on the speaker in your video because it's from a bass guitar cab.. i don't know if the coffee filters that you are using on this video will work in my situation...

  • @uptownphotography
    @uptownphotography 2 роки тому

    Interesting idea with the coffee filter.
    I am currently doing a repair on an old Apex 8" speaker with a huge magnet from the 1960s.
    I have been using Permatex Black Silicone Adhesive Sealant because the surround where the cone meets the frame needs to be flexible from researching I've done on here and a few of the holes are right up to the frame.
    How is that coffee filter holding up as I have still a big hole to patch and I may give that a try. Thanks.

      Paint will add weight to the paper cone and may flake off. So I'd go with something thin and water based like hobby acrylic. Or maybe india ink. No latex , enamel, lacquer or epoxy based paint.

  • @bandersentv
    @bandersentv  11 років тому

    A torn cone would cause the radio to sound terrible, but it would still work. There are plenty of other of other items you need to check if you haven;t already. Power transformer, electrolytic filter capacitors, paper capacitors, field coil or choke, etc.

I also found entire speaker cones that are likely compatible--all pretty affordable. A neighbor threw them out--they look to be in good condition except for the woofer issue(s). On closer inspection I found that the cone on one springs back out when pushed in, but the other cone does not move back out. What would cause this? I will be doing some research when I have time--I guess my questions here is actually a part of that process. Any further help appreciated.
