ULTRA SERIES TRUE COAXIAL RCA<\/strong><\/h4>\n

Maximum Noise Rejection. Pure Signal Transfer.<\/p>\n

The ULTRA SERIES Coaxial RCA is engineered from the ground up for one purpose: deliver a cleaner signal than anything in its class. No compromises. No shortcuts. Just raw signal integrity.<\/p>\n

TRUE COAXIAL SIGNAL ARCHITECTURE<\/strong><\/h4>\n

Unlike twisted-pair designs that rely on symmetry to fight noise, true coaxial geometry physically surrounds the signal with shielding. That means interference is stopped before it ever reaches the conductor.<\/p>\n

BUILT FOR NOISE DESTRUCTION<\/strong><\/h4>\n

16AWG Tinned OFC Braided Shield<\/strong><\/p>\n

A heavy-gauge, high-coverage braided shield acts as the first line of defense, absorbing and dissipating electromagnetic and radio-frequency interference generated from alternators, power cables, DSPs, and amplifiers.<\/p>\n

Foil Shield Layer<\/strong><\/p>\n

The foil shield fills the microscopic gaps no braid can reach-blocking high-frequency noise and electrical hash that kills detail and dynamics.<\/p>\n

Result:<\/strong><\/p>\n

    \n
  • Lower noise floor<\/li>\n
  • Blacker backgrounds<\/li>\n
  • Zero alternator whine<\/li>\n
  • Cleaner signal at high gain levels<\/li>\n<\/ul>\n

    SIGNAL PRESERVATION, NOT COLORATION<\/strong><\/h4>\n

    19.5 AWG Tinned Oxygen-Free Copper Center Conductor<\/p>\n

    Oversized for stability and low resistance, the center conductor preserves signal voltage and timing\u2014delivering tighter bass, improved transient response, and sharper stereo imaging.<\/p>\n

    3.5mm Polyethylene Dielectric<\/p>\n

    Low-loss polyethylene maintains consistent impedance and minimizes signal smear, preserving clarity from sub-bass to high-frequency detail.<\/p>\n

    BUILT FOR REAL-WORLD INSTALLS<\/strong><\/h4>\n

    Flexible PVC Outer Jacket<\/p>\n

    Designed to route cleanly through tight interiors without kinking or stressing the conductor. Durable, vibration-resistant, and built to survive harsh automotive environments.<\/p>\n

    WHAT YOU HEAR<\/strong><\/h4>\n
      \n
    • Tighter, more controlled bass<\/li>\n
    • Increased midrange clarity<\/li>\n
    • Cleaner highs with less grain<\/li>\n
    • More output before noise appears<\/li>\n<\/ul>\n

      ULTRA SERIES<\/strong><\/h4>\n
        \n
      • When silence between notes matters.<\/li>\n
      • When gain is high.<\/li>\n
      • When noise is unacceptable<\/li>\n
      • This is maximum noise rejection\u2014the way a true coaxial RCA cable is supposed to be built.<\/li>\n<\/ul>\n

        \"\"<\/p>\n

        Built for maximum current flow and long-term reliability. Unlike copper-clad or un-tinned wire, our conductors resist corrosion, reduce voltage drop, and deliver consistent power year after year<\/p>\n","protected":false},"excerpt":{"rendered":"
