Synergistic Research Atmosphere SX REL Spec Subwoofer Cable Key Features: 

  • Tricon Silver Matrix geometry with Teflon dielectrics - delivers superior signal integrity for richer, more dimensional sound.
  • Two-stage high-voltage treatment from Galileo SX line - unlocks greater transparency, air, and refinement across the frequency spectrum.
  • Engineered specifically for REL subwoofers - enhances bass depth and control, often requiring less subwoofer output for better balance.
  • System-wide sonic improvements - expands soundstage, enriches midrange, and adds clarity to highs for a more immersive listening experience.

Product Description: 

The Atmosphere SX REL Spec cables bring a level of performance that defies expectations, delivering system-wide improvements similar to what Synergistic Research power cords are known for. During development, listening sessions revealed bass that was deeper and more controlled—enough that the reference system’s subwoofers had to be dialed back. The enhancements didn’t stop there; soundstaging opened up, highs gained air and transparency, and the midrange became richer and more dimensional. These results are achieved through the application of cutting-edge Synergistic Research technologies, including the two-stage high-voltage treatment process pioneered for the flagship Galileo SX line and the Tricon Silver Matrix geometry with Teflon dielectrics. For REL subwoofer owners, these cables represent a must-audition upgrade, offering not just improved low-end performance but a holistic elevation of musical presentation.

UEF Matrix Shield with Graphene Matrix Shielding

The Atmosphere X Series originally explored ways to improve UEF Shielding by positioning UEF Tech at key grid points along cable shields—a method now known as Matrix Shielding. This design lowers the noise floor and enhances clarity. Atmosphere SX refines the concept further by incorporating newly developed Carbon Fibre UEF Tuning Discs, which improve the loom’s ability to cancel noise that could otherwise make high frequencies sound fatiguing. The result is greater resolution, a more holographic soundstage, and improved musicality.

Quantum Tunneling SRX Long Duration High Voltage Conditioning

After perfecting highly natural and holographic cables, Synergistic Research introduced a new high-voltage conditioning process for Atmosphere SX. This process applies a sweeping frequency plot for an extended duration. They experimented with dozens of frequencies in different combinations over a prolonged time period before landing on just the right mix. They even built a new Tesla Coil to handle the excess heat generated during long conditioning sessions. Once finalized, the SRX conditioning process created holographic realism and timbrel accuracy far beyond our previous Tesla Coil conditioning protocol. conditioning sessions. The final SRX conditioning process delivers exceptional timbral accuracy, holographic realism, and three-dimensional presence, surpassing previous Tesla Coil protocols.
