When looking at speaker terminals, the first thing you need to identify is the type of terminal. There are three main types of speaker terminals: spring clips, binding posts, and banana plugs. Spring clips are the simplest type of terminal and are often used for lower-end speakers. Binding posts are a bit more versatile and can be used for both low- and high-end speakers. Banana plugs are typically used for high-end speakers and offer the best connection.
Now that you know the different types of speaker terminals, let's take a closer look at how to identify them. If you're looking at a spring clip terminal, it will have two small metal tabs that protrude from the side of the terminal. These tabs are what you'll use to attach your speaker wire. To attach the wire, simply insert it into the hole in the tab and then squeeze the tab closed with pliers.
Binding post terminals will also have two metal tabs, but they will be larger than those on a spring clip terminal. In addition, binding post terminals will have a threaded sleeve around each tab. This is where you'll screw in your speaker wire using a wrench or pliers.
Banana plug terminals look similar to binding post terminals, but they will have only one metal tab instead of two. The Tab will also be hollow so that you can insert your banana plug connector into it. Once inserted, simply screw on the collar around the base of the banana plug to secure it in place
