To add to above replies, refinishing isn't all that hard. Materials can be simple such as sanding block, sand paper, exacto knife, your choice of glue, heatset or contact and a straight edge and your in business. I've tried both glueing methods and have been more pleased with contact cement; course that's my opinion only.

or search heresy reveneering and you'll find a few projects to review. Bottom line, if your refinishing "beater" speakers then you ain't hurting anything.
