Foundation XL

Subwoofer

At its heart, Foundation XL is a scaled-down distillation of SRX XLhandmade in our California factory using the same core technologies first pioneered in our flagship cable loom.

Just as SRX XL evolved from SRX with greater conductor density and refined treatments, Foundation XL builds on Foundation SX with 33% more pure silver AirString geometries, each suspended in an air dielectric to reduce dielectric interaction and increase resolution. We apply the same SRX XL UEF Compound to Foundation XLs matrix shielding to lower the noise floor without constraining dynamics or transparency. Every cable is then treated with the identical long-duration, high-frequency conditioning process developed for SRX XLenhancing dimensionality, tonal accuracy, and high-frequency refinement.

Each cable includes Purple and Gold UEF Carbon Tuning Discs, letting you voice your cables to system and tasteor run them clean. The choice is yours.

Foundation XL brings the exact same technologies developed for SRX XL to the Foundation seriesdelivering the highest performance-to-price ratio of any cable weve ever manufactured.

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.

Upgrade your XLR

SR XLR

Connectors are not all created equal. After years of research into connector design we chose high purity, high conductivity, low mass Silver as the base material for SR20 RCA and XLR connectors to deliver more refined detail and accurate information. Teflon is used for its dielectric properties and the special design gives the greatest area of contact both for wire and plugs insuring that all of your music will get through. These high performance connectors are standard on our flagship Interconnects and can be added to other cable series interconnects as a performance driven upgrade path.
