FireBird BiWire COMBO joins a FireBird ZERO cable for the treble section with a dedicated FireBird BASS cable for the low-frequency section. Solid Perfect-Surface Silver and Perfect-Surface Copper+ conductors are assigned to geometries suited to the different electrical demands of each half of a bi-wire loudspeaker.
ZERO-Tech supports uncompressed transient current in the upper-frequency leg, while RF/ND-Tech helps manage amplifier-generated radio-frequency noise in the bass leg. The cables are combined at the amplifier end and separated at the speaker for an orderly installation. FireBird COMBO delivers the range’s strongest performance where true bi-wiring is available without moving to the all-silver Dragon assembly.
