Thanks for your reply. Have completely dismantled speaker and discovered that the voice coil had melted and become stuck. Realized that by cutting around the edge of the cone I could pull it and the voice coil out. Many thanks for reply.
the speakers are called Wharfedale E.Seventy and the driver is a 10"moving coil bass driver 2513 AERN 102.60 68.
Guess its the voice coil that id like to insepect for damage.
I have a large bass whalfdale speaker with a huge magnet bolted to its base, and i'd like to know how I can dismantle it so that I can access the wire coil ?
