'Banana Plugs speakers wires'? Is that a new kind of speaker cable, or some new animal?
Jokes apart, banana plugs are the terminators you use to connect your speaker cables to the amplifiers on one side, and the speakers on the other. They will work with ANY speaker cable. Speaker cables are also sold raw like electrical cables, though there are also terminated cables available. It takes a few seconds to strip a cable at one end and insert it into a banana plug.
If you go to any audio ship that sells both cables and banana plugs, and specify the lengths you want, I am sure they will terminate the cables for a few extra bucks.
Cheers.
