  • Dented speaker cone

    Hi
    My new SCM 40 midrange cone has been pushed in. I wish I could blame it on my kids, however the culprit was my pissed 50 year old mate !

    Someone recommended getting the hoover out......

    I would welcome any other suggestions please

    Cheers

    Julian

    Hello Julian, welcome and my commiserations.

    This has never happened to me, but putting "fix dented dome loudspeaker" into a search engine produces video and page hits that mostly suggest using sticky tape applied repeatedly and carefully to the pushed in area to pull it out gradually. Such as .

    I would be concerned that since this is not just a dust-cap, if the edges of the dent were originally sharply creased then even if straightened out without too much stretching of the doped fabric, the remaining small creasing might impact the dome's breakup behaviour. Audibly? Not audibly? I have no idea.

    Good fortune finding the remedy!

    Regards
    John

      Tip 1: Try some sticky tape. Depending on the extent of the dent, it may pop out without any issues.

      Tip 2: Take care using a vacuum cleaner, unless you can dial down the suction. Too much suction may result in further damage to the cone. Perhaps turn the vacuum on then off again and as the suction reduces, place the end of the hose over the dent. The dent should pop out without any damage to the cone.

      Tip 3: Use a card board tube (toilet roll?) place it over the dent and suck the dent out using mouth power.

      Good luck!

        I had this problem with passive 35s. My recollection is that the US importer at the time suggested gently using "duct tape."

        I would ask ATC, I think they would provide a well practiced technique.

        Again, good luck!

          I expect this is now fixed, but for future readers I wonder if the techniques utilised in the motor trade for paintless dent removal/repair might be transferrable.

            Hi julian mallinson. Out of curiosity, did you approach ATC regarding this? I ask as I have two little ones, and it's a scenario I've envisaged several times.
