Shunyata Research Sigma-X Speaker Jumpers | Reference Jumper Cables
Shunyata Research Sigma-X Speaker Jumpers are short reference links for loudspeakers with more than one set of binding posts, used in place of the factory jumper plates when the speaker is driven by a single-wire cable. They come with fixed terminals and are built on the same Sigma-X speaker-cable platform.
Pair them with the standard Sigma-X Speaker Cable. If you'd rather run separate cable legs to each set of posts, see Sigma-X Bi-Wire or Sigma-X Tri-Wire. See all our Shunyata Research cables and power products.

SIGMA-X SPEAKER JUMPERS
Shunyata Research Sigma-X Speaker Jumpers are short reference links that bridge a loudspeaker's binding-post sections when it is driven by one single-wire speaker cable. They are part of the Sigma-X speaker-cable line and come with fixed terminals.
WHO ARE SIGMA-X JUMPERS FOR?
Multi-terminal loudspeakers being used with a single-wire speaker cable, where the factory jumper plates are being replaced by dedicated cable jumpers.
JUMPERS VS. BI-WIRE
Jumpers bridge the loudspeaker's terminal sections while one speaker-cable run feeds the speaker. A true bi-wire cable provides separate cable legs to each terminal section.
TECHNOLOGY
 | TAPc (Transverse Axial Polarizer) is Shunyata Research's patent-pending technology that couples to the electromagnetic fields around conductors, passively reducing electromagnetic distortion. It is part of the Sigma-X speaker-cable platform. |
 | HARP addresses current drift and audio-frequency current resonances that can build up in speaker cables, much like standing waves in a room. The HARP module breaks up those resonances, which Shunyata says improves resolution, focus and coherence. |
 | VTX-Ag conductors combine a pure-silver center core with a concentric outer ring of pure copper. |
 | Fluorocarbon dielectric offers very low dielectric absorption, high dielectric strength and excellent heat resistance. |
 | KPIP v2™ is Shunyata Research's proprietary Kinetic Phase Inversion Process, applied to conductor and terminal metals across the Sigma-X speaker-cable platform. |

CHOICE AUDIO GUIDANCE
Confirm the speaker's binding-post spacing, terminal type, and preferred jumper length before ordering. For systems already using Sigma-X speaker cable, Sigma-X jumpers provide a matching reference-level connection between terminal sections.
FREQUENTLY ASKED QUESTIONS
Do I need jumpers with a bi-wire cable?
Normally no. Jumpers are for single-wire use on speakers with multiple terminal sections.
What is the standard length?
0.25 meter. We list lengths up to 2 meters.
Can Choice Audio help choose termination and length?
Yes. Send us the loudspeaker model and we can help confirm the appropriate configuration.
