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.

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.

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...
