Bi-wiring speakers
Bi-wiring speakers involves using two separate cables to connect a single speaker to an amplifier, essentially splitting the connection for the speaker's high-frequency and low-frequency drivers. By separating the high and low frequencies into different cables, there might be less interference or crosstalk between the signals, potentially leading to clearer sound reproduction.
2 speakers require 4 wires(preferably made of copper) for bi-wired connection. I also use Banana Plugs to simplify the setup.
Cut the required length of the wire, then strip the insulation, twist the stripped wires and secure the wire into Banana Plugs:
See the instructions for connecting speakers to the amplifier, following example is for Marantz PM6006:
And the final setup:
