Choosing a Cable
Speakers normally come equipped with one of two types of connectors, a spring terminal or a binding post. Spring terminals will only accept pin connectors or tinned base wire ends. Binding posts may accept many types of connection, including pin, banana plug or spade.
Spring terminals use spring-loaded connectors to create a compression connection around either pin connector or bare wire. The spring terminal connection is limited by the small size of the actual connection surface, and the fact that the connection itself is not as tight as other options. When using spring terminals, adding a pin connector will help the signal transfer as well as cable durability. The pin will prevent stranded speaker wire from breaking when it is repeatedly inserted and removed from the spring terminals.
Binding posts create a connection to the speaker wire by either accepting banana plugs, or by screwing down over spade connectors. Binding posts make a significantly better connection to speaker wire than spring terminals do because the connections are more mechanically sound.
