I have a pair of really nice three way Pioneer speakers. They stand about 3.50 ft. off the floor and use 12 inch woofers. The foam rings around the circumferance of the cones has rotted away leaving the paper cone supported only by the center suspension. I've seen on the Internet and in catalogs foam repair kits. The sellers make the repair sound so easy but I'm concerned about how you actually center the cone when you glue, ( I assume) these rings into place. Way back in the stone age, 1920's speakes used three shims which you stuck down between the inside of the voice coil and the magnet to center a new cone which you were installing. This was after you glued your old voice coil onto the new cone. You then glued the new cone and the cardboard ring in place. It was a tedious job the say the least. With these foam jobs, do you have to rip off the center cardboard or felt disc which protects the voice coil and magnet area to shim the cone when attaching these new foam rings? If anyone has performed this type of repair and can share the details of the procedure with me I would be very grateful. Thanks for any help. Lenny Stein, Barlen Electronics.
