Synergistic Research
Foundation XL
Speaker Cables

Benefitting from learnings upon the development of the flagship SRX XL cable line, the new Foundation XL Speaker Cables deliver notably improved performance over the Foundation SX series and continue to be offered at attractive price points. While the line as a whole can be thought of as an evolution from the Foundation SX, the cable has been rethought holistically, applying the same improvements Synergistic Research made to their flagship SRX XL cable series.

For each cable type, the 6N pure silver Air Strings was doubled to portray music with more immediacy and resolution, improving upon dynamics and transient response in a completely non-fatiguing way. The same SRX XL UEF compound as described above was applied to improve shielding. And finally, the cables are run through the same SRX XL High Voltage Conditioning treatment that was used for the flagship SRX XL cables.

With Foundation XL, you’ll notice an improved dynamics and a more natural timbre, all with a reduction in noise floor to keep details of the music smoother and more realistic than its predecessor.

UEF Matrix Shield with Graphene
SRX XL Matrix Shielding

In Synerjgistic Research journey to design their latest flagship SRX XL series, they developed an entirely new UEF compound to elevate the performance of their previous Matrix Shielding, which further lowers each cable’s noise floor while lessening restraints a shield may have on signal transmission. They apply this highest level of SRX XL Matrix Shielding to their new Foundation XL cables for a significant jump in performance over the previous generation Foundation SX. Carbon Fiber UEF Tuning Discs developed for the Foundation SX and Foundation XL series cables further refines and enhances the loom’s ability to cancel noise that would otherwise cause high frequencies to sound harsh or fatiguing.

Enhanced Cable Geometries
6N Pure Silver Airstrings, Multiplied

While voicing the Foundation XL, the researchers found that doubling the 99.9995% Pure Silver Airstrings resulted in a cables that are faster and more resolving, adding texture and body while improving dynamics and transient response without adding fatigue.

Quantum Tunneling
SRX XL High Voltage Conditioning

The new SRX XL High Voltage Conditioning is most advanced process for treating cables with 1,000,000 Volts of electricity at specific frequencies and pulse modulations for long durations, creating a canal in the conductor material and contact points at the molecular level that allows electrons to flow more freely. This new process improves upon the SRX High Voltage Conditioning process by employing new extended duration sweeping frequency plots and advancements to Synergistic Research Tesla Coil, resulting in SRX XL cables to sound even more open and accurate than the cables before them. For Foundation XL, we utilize this exact conditioning process, which we found to contribute to the large performance improvement in this series, bringing the voicing of the Foundation XL closer to that of the SRX XL.

Included Carbon Tuning Discs
Tune to Perfection

Included with Foundation XL interconnects, speaker cables, and power cables, Carbon Tuning Discs (€219,00 MSRP) are a spinoff of the new Atmosphere SX Loom where they are placed inside cables at key locations and are instrumental in creating the SX sound. Based on Synergistic Research patented UEF technology, each disc gets treated with a unique UEF compound that interacts with EM fields wherever you place them in your system or on cables to improve sound quality. The conductive carbon fiber material of the disc enhances the interaction between the UEF compound and the surrounding EM fields where it is placed. The Gold- Carbon Tuning Discs flesh out rich harmonics combined with a clarifying effect in the sound field for a more lifelike and holographic presentation. Purple- Carbon Tuning Discs get treated with a UEF compound that enhances clarity and extension in the soundstage even beyond Gold.
