I recently bought a receiver for the 1st time, and I'm just learning about Audio tech. The fisher floor speakers that I'll be using have 2 screws in the back of each one for connecting wire. Above one screw it says "8 Ohm" with an arrow pointing to the screw. Above the other screw it says "common" with arrow pointing to screw. What does "common" refer to? And, how do I connect these speakers? (there's also an RCA Plug connection).

Connect the 8ohm-marked-terminal to the (+) terminal on the receiver and the other to the (-) terminal. Avoid the RCA.

What Kal said. The best method is to crimp appropriate-sized spade lugs onto the speaker wires, which slip quite nicely under the screws. Wrapping the wire around the screw doesn’t usually work too well, as it will tend to “splay†the wire.

Thanks for the info.

Where can I find spade lugs?

And I'm still curious as to what "common" refers to.

You can get garden variety lugs virtually anywhere – auto parts stores, hardware stores, Radio Shack. Use blue for 16-14 ga. wire, yellow for 12-10 ga.

If you want the fancy ones, Radio Shack should have them, too.

You’ll need a crimper like this for the cheaper lugs. Generally a handy tool to have around – crimps any of the colored connections – blade and ring lugs, butt splices, etc.

Oh yes - the "common" simply refers to the speaker (-) connection.

Common, negative, black. One terminal. Hot, positive, red. Other terminal.


You don't need spade lugs if you strip the wire carefully and make sure no "frizzies" short from one screw terminal to the other.


When I saw the title of this thread, I immediately thought of "white van" speakers, because they definitely have a "screw connection."

It wasn’t uncommon for old speakers like Signal Green’s Fishers to have screw terminals. I used to have an old pair of Genesis Physics speakers that had them.
