Foundation SX Speaker Cables

We engineered Foundation SX speaker cables to include core Synergistic Research technologies in the purest expression possible. We intended to make a complete loom of cables affordable for audiophiles who otherwise might not take that plunge. The loom effect acts as a performance multiplier within the Foundation SX line to deliver sound-staging, low noise floor, dynamics, and musicality beyond Foundation’s individual price points.

Foundation SX distills technology from our highest-performance cables, so you can mix and match them with Atmosphere SX, Galileo Discovery, and SRX to maintain the loom effect when a total commitment to our higher-end cable families is not practical; they’re that good.

Foundation SX speaker cables start with Air String geometries comprised of pure silver mono-filament conductors in an air dielectric hand-made in our California factory for high levels of detail and natural sound-staging combined with parallel heavy gauge copper matrix conductors, so you experience low frequencies with extension and control. We then apply a UEF Compound first developed for our flagship SRX cable loom for a lower noise floor than was possible with the original Foundation Series for enhanced detail with enhanced musicality.

We then apply the same Long Duration High Voltage Conditioning Process that enables SRX cables to lead the industry with realistic sound stage scale plus resolution and musicality in equal measure. Lastly, we included newly developed UEF Carbon Tuning Discs so you can custom voice Foundation SX speaker cables to your system or run them straight. The choice is yours.
