This is one piece Demo AUDIOQUEST SUB-1 RCA cable in 4.5M.

Designed specifically for use with subwoofers and the low-frequency signals they handle, Audioquest's SUB-1 is a bit different than Audioquest's regular audio interconnects. SUB-1 uses larger conductors for better low-frequency reproduction, heavy silver-plating for greater snap and slam and PE Air Tubes for greater speed and articulation.

Audioquest 21AWG solid-core LGC conductors offer greater bass definition than stranded designs, the heavy 2.5% silver plating improves speed and slam characteristics, the PE Air Tubes minimize time-domain smearing improving pitch definition and articulation, SUB-1's three conductor design insures optimum performance, whether single-ended (RCA plugs) or balanced (XLR plugs), 100% coverage shield insures noise-free performance. Topping it all off, Audioquest's silver-plated RCA plugs are welded to SUB-1 using 8,000 ampere, reducing distortion and improving conductivity.

Audioquest cables are legendary in audiophile circles for their neutrality and resolution. For 28 years, Audioquest has worked tirelessly to achieve sonic neutrality in all their cables, regardless of price. Ensuring that music flows unchanged and uncolored requires removing the myriad distortions that occur when a signal flows through a cable. To accomplish this, Audioquest has bypassed conventional cable design and focused their efforts on both the physical properties and sonic characteristics of the conductors and connectors, as well as all materials used in the creation of their cables.
