The Type 4 speaker cable model was first introduced around 1983. It might not have been the most aesthetically pleasing cable, but the performance advantage of its polypropylene insulation was spectacular and highly appreciated. Several evolutionary steps later, the current version of Type 4 was introduced in 1995. Its design, so well balanced, hasn’t changed since then, and it still isn’t changing.
The Type 9 Low-Distortion & Low-Noise speaker cable is essentially a Type 4 with better metal and additional layers and techniques for noise dissipation, providing more effective noise control than any previous Type 4 iteration.
Furthermore, the conductors of the Type 9 are slightly larger than those of the previous 4-series cables. The conductors are a bit more spaced apart, reducing interactions between adjacent conductors by 35%.
SOLID PERFECT-SURFACE+ SONIC-SIGNATURE CONDUCTORS Solid Perfect-Surface Copper+ (PSC+) conductors prevent strand interaction, a major source of ear-fatiguing transient intermodulation distortion. The astonishingly smooth and pure Perfect-Surface Copper+ eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N, and other premium coppers. The superior purity of PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor.
SOLID CONDUCTORS Eliminate harshness and confusion due to strand interaction.
MULTI-LAYER CARBON-BASED NOISE-DISSIPATION Multi-Layer carbon-based Noise-Dissipation, combined with Direction-Controlled conductors and shielding, significantly lowers the noise floor and reduces amplifier Transient-Intermodulation Distortion (TIM).
STAR-QUAD GEOMETRY Balanced Star-Quad Geometry reduces time-smearing while preserving dynamics and clarity.
