About the Reference High Definition Links

Walker Audio Reference High Definition Links are passive external Zobel filters for loudspeakers. They connect in parallel across the speaker binding posts to reduce very-high-frequency electronic noise and RFI reaching the speakers. The links use ultra-pure silver wiring and spade connectors, with the components housed in a wooden block and shielded by conductive copper foil. They must be installed with the marked polarity observed and positioned on top of the speaker-cable spades. Bi-wired and tri-wired speakers require two and three pairs, respectively.
