Synergistic Research Foundation XL Speaker Cables, Pair

Synergistic Research Foundation XL Speaker Cables Key Features: 

• Doubled 6N Pure Silver Air Strings – delivers greater resolution, dynamic impact, and transient speed while maintaining a smooth, non-fatiguing presentation.
• SRX XL Matrix Shielding with Graphene and UEF Compound – lowers the noise floor and enhances clarity without constraining signal flow.
• SRX XL High Voltage Conditioning – improves electron flow for a more open, accurate, and lifelike sound presentation.
• Carbon Fiber UEF Tuning Discs – allow fine-tuning of tonal balance and soundstage, enhancing either harmonic richness (Gold) or clarity and openness (Purple).
• Redesigned from the Ground Up with SRX XL Technology – brings flagship-level innovations to an accessible price point, offering a substantial step up from Foundation SX.

Product Description: 

Drawing on advancements made in the design of the flagship SRX XL cable line, the new Foundation XL speaker cables deliver a clear step up in performance over the Foundation SX series, while maintaining approachable pricing. Though an evolution of Foundation SX, Foundation XL has been re-engineered from the ground up, integrating the same breakthrough technologies first developed for SRX XL.

Each cable doubles the number of 6N pure silver Air Strings, presenting music with greater immediacy, resolution, and dynamic impact, while enhancing transient response in a smooth, non-fatiguing manner. The SRX XL UEF compound is applied to strengthen shielding, and every cable undergoes the same SRX XL High Voltage Conditioning process used for the flagship line.

With Foundation XL, listeners can expect heightened dynamics, more natural timbre, and a lower noise floor, allowing subtle musical details to emerge with a smoother, more lifelike presentation than its predecessor.

UEF Matrix Shield with Graphene SRX XL Matrix Shielding

In creating the flagship SRX XL series, Synergistic Research developed a new UEF compound that advances its Matrix Shielding technology, reducing the noise floor even further while minimizing the signal constraints typically associated with shielding. This state-of-the-art SRX XL Matrix Shielding is now applied to the Foundation XL line, delivering a substantial performance upgrade over the previous Foundation SX. To further refine musicality, Carbon Fiber UEF Tuning Discs—engineered specifically for both Foundation SX and Foundation XL—enhance noise cancellation, preventing high frequencies from sounding harsh or fatiguing.

Enhanced Cable Geometries—6N Pure Silver Airstrings, Multiplied

While voicing the Foundation XL, Synergistic Research discovered that doubling the 99.9995% pure silver Air Strings produced cables that are quicker and more resolving, with greater texture and body. This refinement enhances dynamics and transient response while preserving a smooth, fatigue-free presentation.

Quantum Tunneling—SRX XL High Voltage Conditioning

The SRX XL High Voltage Conditioning process represents Synergistic Research’s most advanced treatment, applying 1,000,000 volts of electricity at carefully chosen frequencies and pulse modulations over extended durations. This creates pathways within the conductor material and contact points at the molecular level, enabling freer electron flow. Building on the original SRX process, the XL version introduces longer duration sweeping frequency plots and enhancements to the Tesla Coil, resulting in an even more open and accurate sound. Foundation XL cables benefit from this same conditioning method, a key factor in their substantial performance gains and voicing that approaches the flagship SRX XL series.

Included Carbon Tuning Discs—Tune to Perfection

Foundation XL interconnects, speaker cables, and power cables include Carbon Tuning Discs derived from the Atmosphere SX loom where they help define the series’ signature sound. Each disc incorporates patented UEF technology and is treated with a specialized UEF compound that interacts with EM fields to elevate performance. Constructed from conductive carbon fiber, the discs intensify this interaction, further improving system transparency and refinement. Gold Carbon Tuning Discs enrich harmonic texture while adding holographic realism, while Purple Carbon Tuning Discs extend clarity and soundstage openness even further for heightened detail and dimensionality.
