Foundation SX XLR Subwoofer Cable

$599.00
Frequent Flyer

Foundation Series cables started four years ago when our Lead Designer set out to distill 30 years of cable design into a single cable loom with performance capable of taking on giants at an approachable price. This led to the launch of the industry’s highest price-performance ratio cables, the Foundation Series. Fast forward three and a half years, and we’ve developed new technologies instrumental in making our SRX cable loom the world’s highest-performance price no-object cable line. During the SRX development program, we landed on exploded Pure Silver Air String Geometries, where parallel cable runs based on Foundation Series Air Strings ran in parallel with newly developed technologies that combine to create the SRX cable loom. We have now applied all transferable SRX technologies, namely a new Long Duration High-Voltage Conditioning process and a new UEF Compound, to Foundation SX for a massive leap in performance. We also include Carbon UEF Tuning Discs so you can custom voice Foundation SX to your system or plug and play without custom voicing. 

2 each RCA, 4 each XLR and REL Spec Silver Air String:

  • Silver Air Strings: 99.9999% pure monocrystal silver conductor
  • 4 separate conductors RCA / 8 separate conductors XLR
  • Dielectric: Air (sealed)
  • Shielding: Silver Braid -Quantum Tunneled

RCA and XLR Connectors:

  • Silver Teflon SR 20 RCA or Neutrik NC3FX-BAG, NC3MX-BAG XLR connectors

Build Notes:

  • 8 (RCA) 12 (XLR) point-to-point hand soldered connections
  • SRX 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 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
