Wire Strengths

  • 99.999% oxygen-free copper, which has better conductivity, and more importantly, minimizes phase shifts and distortions that degrade sound quality, reduces resistance, is less likely to corrode so lasts longer, doesn’t heat up as much as other conductors, and is less likely to ‘short’
  • 14 AWG (or 14 gauge) which makes this heavy-gauge wire that has less impact on sound quality over longer distances
  • Densely stranded for lower signal loss
  • Extended frequency response, so audio with higher overtones (e.g. music with instruments like cymbals and pianos) sounds more alive
  • Easy-to-handle round cable construction
  • Flexible and easy to strip, so you or your customers can easily install it, even around tight corners
  • RhinoPac® packaging solution, designed to provide smooth pulling during installation while providing reliable protection against crushing and water damage during transport or storage
  • A ripcord underneath the jacket, to make it easy to remove during installation
  • Legend markings for channels, rooms, and zones so installation is faster and easier
  • Ascending and descending E-Z footage markings, so there’s no need for a measuring tape during installation
  • Sunlight-resistant (it complies with the UL 1581 standard in regard to resistance to sunlight in outdoor installations), so it can be installed outdoors if desired
  • Can be installed underground, directly in contact with the soil, even in wet locations, so you can use it no matter your conditions
  • RoHS compliant, so you can rest easy knowing it doesn’t contain hazardous substances that could harm you, your employees, or your customers (more information about this is in our Green Leaf Label)
  • Third-party verified for guaranteed performance, so it will stand up to your needs or those of your customers
  • Operates in a wide range of temperatures, so it can be installed in any area in any part of North America
  • Versatile applications including high-end audio transmission in professional studios and home theatres, car stereos, high-resolution monitoring, and speaker-level analog audio
