Unique “bi-wire” technology.
WBT® Cu connectors.
Eighteen discrete conductors [9 awg / 6.6mm2].
BiFocal-X is as elegant as it is performance oriented. Designed
specifically for "bi-wire" loudspeaker systems, the BiFocal-X delivers the clarity and openess sought after by speaker designers and enthusiasts alike. The dual-concentric circuits of the BiFocal-X™
feature a total of eighteen individual VariStrand™ conductors: six for
the inner, “high-frequency” circuit and twelve for the outer,
“low-frequency” circuit. Electrical isolation is accomplished by
correlating circuit geometries with an isolating ESD matrix. BiFocal-X is terminated with WBT® connectors.
“…the BiFocal’s strengths…; detail, speed, sharp transients,
exceptional reproduction of dynamic and pitch subtleties. …how easy it is to view the BiFocal as an evolutionary advance.”
