Development listening sessions revealed bass that was deeper, tighter, and so powerful that the reference system’s subwoofers had to be turned down. Additional improvements included expanded soundstaging, remarkable air and transparency in the highs, and a fuller, more expressive midrange. These results are achieved through the application of all current SR Technologies, including the two-stage high-voltage treatment first introduced with the Galileo SX cables, along with Atmosphere SX Tuning Modules that allow users to tailor the cable’s voice to their system and preferences. The design also features handmade silver Air String Geometries and the latest Tricon Silver Matrix geometry with Teflon dielectrics. Performance can be further enhanced by connecting the included shield ground to a Synergistic Research Ground Block. For REL subwoofer owners, these REL Spec cables are a must-audition, delivering not only enhanced low-end control but a complete sonic upgrade across the entire system.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-6naz0isypk\/images\/stencil\/original\/image-manager\/relspecreference-2.jpg?t=1757347845\" alt=\"Synergistic Research Atmosphere SX Reference REL Spec Subwoofer Cable\" width=\"1200\" height=\"700\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eUEF Matrix Shield with Graphene Matrix Shielding\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eThe 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eQuantum Tunneling SRX Long Duration High Voltage Conditioning\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eAfter 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eGold and Silver SX Tuning Bullets—Redefining Refinement\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eThe Galileo Tuning Circuits have been completely reformulated and re-voiced with technology developed for the ultra-resolution and musical Galileo SX line of cables. The new Silver Bullets deliver greater detail along with added warmth compared to the previous generation, while the Gold Bullets now provide even more musicality, liquid smoothness, and a touch of additional air and detail. For optimal results, Synergistic Research recommends allowing any cable to settle in the system for 72 to 96 hours without removal or handling and without Gold or Silver Bullets attached. Once settled, audition the Gold Bullets first, followed by the Silver Bullets, to determine which voicing produces the most natural musical presentation in the system. Atmosphere Excite SX includes the RED UEF Tuning Module, while Atmosphere Euphoria SX is equipped with both RED and BLUE UEF Tuning Modules for greater
