Synergistic Research Foundation SX Cable

This cable is engineered with the specific termination requirements of REL subwoofers in mind. It ensures a direct, secure connection that maintains the integrity of the high-level signal path, allowing for a true plug-and-play setup without needing adapters.

The UEF carbon tuning discs are designed to manage resonance and high-frequency noise. By attaching them to the cable, you can subtly adjust the voicing of your subwoofer to better integrate with your main speakers, helping to smooth out the transition between the two.

Not at all. While silver is known for its speed and detail, the Foundation SX uses pure silver monofilament air strings specifically to improve low-frequency definition and impact. The goal is to reduce grain and noise, which results in a tighter, more articulate bass response rather than a brighter one.

Quantum Tunneling is a proprietary process that treats the cable at a molecular level to improve electron flow. In practical terms, this reduces the noise floor of the signal, which helps your subwoofer sound clearer, more dynamic, and more realistic.

This cable is specifically terminated for REL subwoofers. While it may physically fit other subwoofers that use similar high-level connection standards, it is optimized for the REL architecture and we recommend it primarily for that brand.
