Bi-wiring uses separate speaker cables from the amplifier to the speaker’s high-frequency and low-frequency input terminals, with the terminal jumpers removed. This separates the signal paths through the speaker’s crossover and can help reduce interaction between high- and low-frequency current, provided the speaker and amplifier support the connection.

To install bi-wired speakers, use a compatible amplifier or AV receiver, speakers with separate high- and low-frequency binding posts, and two speaker-cable runs for each speaker, terminated with compatible banana plugs, spade connectors, or bare wire. Remove the speaker’s jumper bars, then connect each cable run to the matching terminals, or use separate amplifier channels and an appropriate crossover when configuring a bi-amped system.

Bi-wiring uses separate speaker cables from the same amplifier channel to a speaker’s high- and low-frequency terminals. Bi-amping uses separate amplifier channels for those terminals, and may allow additional crossover control when the system supports outboard crossovers.

Choose bi-wired speakers based on the room, speaker placement, listening goals, and whether your amplifier supports separate high- and low-frequency connections. Confirm that the speakers have separate terminals, use the recommended cables and crossover setup, and consider in-room, in-wall, bookshelf, or floorstanding designs to match the system layout.
