Not really, they can be used for that, but they are separate pair that can be used in any combination. By-wired comes usually with specific four conductor cable and in modern systems with speakON connectors which prevent any wrong way connection to the amp or speakers. Unless you have your own made banana plug terminals in both ends (amp and speakers) you would have to change the wire terminals to speakON at the speaker side at least. If you have separate amps running power for bi-amp speakers (pros use stereo and one channel to each driver and have speakON to connect) you can connect that end according to the way to connection is provided and then join the speaker end with speakON or if there is as mentioned separate connection to use them. In Europe the law requires speakON connections for all new systems to prevent mistakes. All new pro amps also have them in N.Am.
