    This stuff is amazingly built, its very flexible so if youre using it for surround speaker runs it will lay flat on the ground and not look all curly and un even. It lays flat and was easy to strip and the copper was very strong and no strands came off during stripping. High recommend this stuff. Its thick, and heavy. But for sure quality.

    I bought banana plugs because between the thickness of this speaker wire and how close Sony put the inserts, there’s no way to get the wires in clean without a mess of exposed wire. The banana plugs keep it neat. I wish the speaker wire came in colors that worked well with my walls , but it’s fine. I bought too much and Amazon was great about returning the unused spool.

    Bought this cable some time ago but just this past weekend had the time to run it. I’ve always been one who believed that the kind of wire used from amp to speakers had little affect on sound. Changed my mind after replacing the generic 12 g wire I was using previously. Could even tell the difference with a/b test. Easy to strip and easy to run. Highly recommend.

    Excellant quality cable, its refreshing to see a manufacturer not lying about their specs (theres so much BS in audio today). Im assuming length is as stated, wasnt a big deal for me anyway, as I didnt need the entire reel. 50 cents a foot is a actually a pretty good deal for cable of this quality, you get what you pay for here. As for arguments on cables improving sound quality noticeably, thats another topic, most systems well not see a difference between cheap and good cables at normal run lengths. But again, its nice to not have fake specifications, which are so prevalent in consumer audio today.

    Hard to find larger gauge speaker cable in large lengths for a decent price.

    Excellent wire. Definitely 12 gauge. Flexible and 100% copper. This wire is the real deal, and worth every penny.

Plain and Simple Specifications

  • Wire type - CCA or OFC

These materials are commonly used, but not commonly stated when shopping online. Know what you are purchasing. Both metals are capable of performing up to their rated loads.

  • American Wire Gauge

Wire gauge is crucial to powering your system correctly. Undersized cable will create unsafe conditions and may shorten your amplifier"s life.

True American Wire Gauge (AWG) Products

  • Using American Wire Gauge standards, the gauge of stranded wire is determined by the total area of the conductor.
  • To calculate this you would take the area of each strand and add it together. This area, in square mm, then determines gauge.
  • Speaker Wire is often written as 12-2 or 12/2. This means 12 gauge x 2 conductor, both positive and negative signal are carried within one cable and are each 12 gauge.
  • Diameter is not as critical with stranded wire, this is due to the tiny air gaps between each strand. Diameter may fluctuate with strand size and how tightly wound the rope of the cable is.
  • The smaller the number, the larger the wire, until you reach zero or aught (0). Most speaker wire ranges from 10 to 16 gauge. 18 to 22 gauge is often much too thin for most Home Theater applications.
  • Based on AWG, the true gauge of this cable is 12 Gauge

Oxygen Free Copper - The standard in audio

  • Quality cables use quality materials. Oxygen Free Copper is copper of at least 4n purity. That means the conductor must be at least 99.99% copper.
  • Copper speaker wire provides lower resistance than similar sized CCA cable. This means improved frequency response.
  • The ultra fine OFC strands in the Kord speaker wire allow for more current to flow as AC voltage travels on the conductors edges.
  • Another benefit to the high strand count, our cable is incredibly flexible
