Synergistic Research Foundation XL Speaker Cable

Foundation XL Speaker Cables Benefitting from learnings upon the development of our flagship SRX XL cable line, our new Foundation XL speaker cables deliver notably improved performance above 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 we’ve made to our new flagship SRX XL cable series. For each cable type, we’ve doubled the 6N pure silver Air Strings to portray music with more immediacy and resolution, improving upon dynamics and transient response in a completely non-fatiguing way. We apply the same SRX XL UEF compound as described above to improve shielding. And finally, the cables are run through the same SRX XL High Voltage Conditioning treatment that we use for our 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.     Foundation Cable Series Awards                         UEF Matrix Shield with Graphene SRX XL Matrix Shielding In our journey to design our latest flagship SRX XL series, we developed an entirely new UEF compound to elevate the performance of our previous Matrix Shielding, which further lowers each cable's noise floor while lessening restraints a shield may have on signal transmission. We apply this highest level of SRX XL Matrix Shielding to our 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, we 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 our 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 our 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 ($199.95 MSRP) are a spinoff of our new Atmosphere SX Loom where they are placed inside cables at key locations and are instrumental in creating the SX sound. Based on our 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.     Integrated Frequency Transmission (IFT) A Better Way to Bi-Wire     SPECIFICATIONS 8 each Silver Air String Silver Air Strings: 99.9999% pure monocrystal silver conductor 8 separate conductors Air sealed / Teflon Dielectric Shielding: Silver Braid -Quantum Tunneled SRX XL UEF Matrix Shield with Graphene 4 each High Current Copper Air String Copper Air Strings: 99.95% pure copper conductor 4 separate conductors Air sealed / Teflon Dielectric Shielding: Silver Braid -Quantum Tunneled SRX XL UEF Matrix Shield with Graphene SR BoFa Banana and SR Silver Spade Connectors 16 point-to-point hand soldered connections SRX XL Matrix Shielding: UEF coating with Graphene is applied directly to connectors significantly reducing the noise floor and allowing a purer signal to transfer with less grain providing more warmth and detail Silver Solder: 4% Hand build time: 2 hours SRX XL Quantum Tunneling: After the cable is completely assembled all connections and cabling are treated with 1,000,000 volts of electricity at specific frequencies and pulse modulations, creating a canal in the conductor material and contact points at the molecular level that allows electrons to flow more freely. This allows the maximum amount of low level information through the conductors and provides for the highest amount of realism in your music Secondary UEF Blue Treatment originally developed for SR Blue Fuses 5 day Burn-in: 2 step process Hand crafted in our California factory
