[QUOTE="fdlsys, post: 920565, member: 2310"] "Fabric glue" probably - similar formulation, looks and smells as wood glue but it seems to bond pretty much anything and most importantly it remains flexible once it cures. Contact type glues do not give you the opportunity for fine adjustment because they bond on contact. I use Acrilex but I have tested with "fabric glue" also and it holds well. I glue the surround to the cone first and leave overnight. Then, drive the speaker with 60-100Hz signal from function generator to center it and then glue to the basket. While the glue is still wet I run the +/- DC offset from the function generator which pushes the cone up and down (remains centered running on the base frequency) to make sure there is no coil contact with anything. Once perfectly centered I disconnect the function generator and let it stand for 24hr to cure. [/QUOTE]
