Replace them all with a good quality post, and solder the wire to the post. The crossover with the terminals unscrews and can be pulled out of the speaker. I would also flush mount the board that holds the post so that you have much easier access to the terminals.
Broken speaker terminal, Dunlavy IVA
Just broke a speaker terminal on one of my Dunlavy IVAs. Anyone know what the manufacturer and model number for a replacement? Or, should I replace them all with better quality? Also, how easy to replace? Thanks!
