Four-conductor speaker wire is designed for high-fidelity audio systems and supports two advanced connection methods: bi-wiring and bi-amping. Unlike standard speakers with a single pair of terminals, compatible speakers feature two pairs of binding posts—typically one for high frequencies (tweeters) and another for low frequencies (woofers). These configurations allow for improved signal separation and audio performance.
Key Features
-
Bi-Wiring
- Uses a single amplifier with separate wire runs to each frequency section of the speaker
- Both wire pairs connect to the same amplifier terminals
- Provides dedicated pathways to different sections of the speaker’s crossover network
-
Bi-Amping
- Uses separate amplifier channels for different frequency ranges
- Requires:
- Two amplifier channels per speaker
- Four-conductor wire or two separate speaker cables
- Speakers with removable jumpers between terminal pairs
- Offers greater sonic benefits by separating amplification stages
-
Technical Advantages
