Hello, I have a philco speaker that was stored incorrectly on top of something that over time pushed the cone in too far. now the cone voice coil sits too low in the magnet part because of the cone and center cone support have been like this for a while. Can it be repaired or fixed? I would think it could be, but not sure yet on how to go about it. It has the typical philco spider support with the 3 cardboard or something arms that go out to the cone in the center. I am thinking I could put the cone back to where it is supposed to rest and glue or silicone the cone spider where it it damaged.
Is there a way to dissolve the glue that keeps the cone glued to the speaker housing such as alcohal or something else.

Think I would spray some water on the cone to moisten and reform the cone being careful to keep the central cylinder free to prevent destortion. Best glue for repairing the cone is loctite super glue gel applied the the back side (to hide repairs). A super glue accelerator from a hobby shop will make repairs a lot faster and easier.

Hi,
Cardboard will take a set over time. But you do have the right ideas.

There are a few products that will dissolve the adhesives, and many picture framing shops can get it. "UnSeal" is one product that works very well, Larson Juhl, who supplies many picture framing stores will have it available for those stores they supply who do not have another local supplier (due to shipping requirements for "hazardous" materials. There are other suppliers too of similar material, Twin City Moulding They are owned by another company, (For Midwest US and Canada) but I do not recall whom. This material has worked fine and did not attack any foam surrounds that I have used it on to date.

Otherwise with due precautions for ventilation and skin contact, methanol "might" work for you, Acetone will work on original glues, but this and methanol will melt foam surrounds.

The glue used on all rigid portions of contact on the basket for the woven spider, cone edge and between the voicecoil form and cone are a celluloid glue originally, however Duco Cement and Ambroid are pretty much the same for characteristics.

For cone repairs, the best adhesive I have found so far because it flexes with the paper- most adhesives do not, or require so much area of coverage that there is no hiding them, is a product available at many hardware stores, and it is marketted with many names, but "Plumbers Goop", is the product I use. For a close fitting tear, you can actually apply it with a toothpick, and you only really need to get it on the tear itself. It does take a little while to cure.
