There are several ways you can opt to terminate your speaker wire, depending on what connections your amplifier and speakers have. The easiest and most direct connection is bare wire, but you risk breaking off strands each time the wire is disconnected, or possibly causing damage if strands from each connection touch one another or your equipment.
If you expect to be disconnecting and reconnecting your speakers often, perhaps to move them in other locations, you may find banana plugs, spades, or pins more convenient. Most Rotel equipment accepts banana plugs, but not all accept spades or pins. Check with your dealer if you will be using spades or pins.
You can purchase pre-terminated wire to eliminate any doubts you may have assembling your own cables.+
