Shunyata Research Sigma-X Speaker Jumpers | Reference Jumper Cables
Shunyata Research Sigma-X Speaker Jumpers are short reference-grade links for loudspeakers with multiple binding-post sections when a full bi-wire or tri-wire cable is not being used. They are designed to maintain a high-quality connection between the speaker's terminal sections instead of relying on the factory jumper plates supplied with many loudspeakers.
Choose Sigma-X Jumpers when using a single-wire Sigma-X speaker cable with a compatible multi-terminal loudspeaker and you want the jumper connection to remain at the same reference level.

Who are Sigma-X Speaker Jumpers best suited 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 the terminal sections.
Technology
Shunyata identifies Sigma-X Speaker and Jumper products within the same reference-level speaker-cable line. The Sigma-X speaker-family technology platform includes VTX-Ag conductor architecture, TAPc, HARP, fluorocarbon dielectric materials, and KPIP v2 processing. The blocks below describe those family technologies without assigning jumper-specific numeric module counts that Shunyata does not separately publish for the jumper configuration.
TAPc
Patent-pending Transverse Axial Polarizer technology couples to electromagnetic fields surrounding conductors and is designed to reduce electromagnetic distortion.
HARP
HARP addresses current drift and audio-frequency current resonances that can occur in speaker-cable conductors.
VTX-Ag
VTX-Ag conductor geometry combines a pure-silver center core with an outer concentric ring of pure copper.
Fluorocarbon
Fluorocarbon dielectrics offer very low dielectric absorption, high dielectric strength, and strong heat resistance.
KPIP v2
Shunyata Research's proprietary Kinetic Phase Inversion Process is applied to conductor and terminal metals as part of the Sigma-X speaker-family 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 primarily for single-wire use on speakers with multiple terminal sections.
Can Choice Audio help choose termination and length?
Yes. Send us the loudspeaker model and we can help confirm the appropriate configuration.
