I was hoping someone could help me here please? I bought a pair of Lafayette sk 112 speakers from ebay and 1 was having issues with the voice coil on the bass driver. I would like to replace it and I was wondering if anyone here knows the correct size and where I might be able to buy them? I am really no good on measurements. Any help would be greatly appreciated. Goodmans made these for Lafayette if that helps and are 12 inch triaxial
