Raising the Bar for Speaker Cable Performance

The Shunyata Research Theta speaker cable represents a breakthrough in high-performance audio cabling. Created with scientific innovation that has established Shunyata as a key contributor to the world's top recording studios and heart-surgery labs, Theta delivers uncompromising performance that raises the bar for all products in its category.

The Sound and Fury

Theta cables disappear, allowing your system to express sudden dynamic shifts in timing and frequency extension with effortlessness and nuance. A loom of Theta cables allows a complex system of electronics and speakers to speak with a single coherent voice.

Like their more affordable Gamma Series counterpart, Theta cables imbue the system with an unassailable sense of coherence, as if everything is in focus, without distortion or hard transients. There is an absence of perceived noise, allowing spectral and textural subtlety to come to the fore. Unlike common copper cables, Theta delivers explosive dynamics and pitch-perfect frequency extension, even when compared to far more expensive cables. Theta's larger gauge VTX™ conductors add weight, dimensionality, and an expansive, room-filling soundstage.

Revolutionary VTX™ Technology

VTX™ (Virtual Tube) Conductors
Shunyata's exclusive VTX™ conductors are made in the shape of virtual tubes. The core of the conductor is completely hollow, minimizing skin effects and random eddy currents. They are produced using OFE Alloy-101, the highest purity copper available.

ArNi® Wire
ArNi® is Shunyata's proprietary wire designed to be the finest quality available for audio purposes. It begins with the highest purity copper – OFE C10100 or Ohno (single crystal). Then it's formed in virtual hollow tubes, eliminating skin effects and eddy current distortions. Premium fluorocarbon insulation minimizes dielectric absorption and re-radiation, greatly improving resolution and clarity.

Advanced Technologies

• OFE Alloy 101 Copper - Highest grade copper with minimum 99.99% purity and 101% IACS conductivity rating. Certified by ASTM F68 C10100
• Fluorocarbon Dielectrics - Aerospace-grade insulation with very low dielectric absorption, high dielectric strength, and exceptional heat resistance. Reduces dynamic compression and improves sonic clarity
• KPIP v2™ Processing - Four days of continuous Kinetic Phase Inversion Processing refines conductor metals at the atomic level, dramatically reducing burn-in time and delivering a relaxed, life-like presentation
• STIS v3 Interchangeable Terminals - Solid tellurian copper terminals with pure gold plating. Offers all the performance of fixed connectors with endless flexibility to change between banana and spade on the fly
