    Couldnt be happier with these cables. The cords are flexible, easy to strip and seem to be the correct gauge. The writing on the one cable is clear and repeats enough times that it is easy to know which cable should be red and which cable should be black.

    The only reason I gave this three stars is because it was short by about four feet of the fifty foot I was supposed to get. I just had enough to complete my job for the client. I always measure new speaker cable before I start to use it. I measured this one three times as I could not believe it was four feet less than the advertised 50 feet. Does not come on a spool, just a wrapped bag. I sent the seller a notice thru the Amazon system, they never responded. I would have given this product five stars if it was a true 50 feet. I install Home Theatres for my clients, since it was long enough and I could not wait as I was on the job I used it. Good thing I always build in a slop factor on speaker cable. This is the first time this ever happened to me and I have bought several different types of speaker cable over the years.

    I love it, solid coper and as advertisedI love it, solid coper as advertised. Extremely high quality. Only thing wish it was a round type cable, not a flat one, as it is not as simple to roll up nice and neatly.

    This is very high quality wire. Its very flexible, easy to strip and separate and nice looking. I look for high strand count and OFC when purchasing speaker wire and this has both.

    Great quality and very durable. Im impressed.

Kord Ultra Flex 12 Gauge Speaker Wire - over sized Oxygen Free Copper speaker cable provides superior frequency response compared to smaller, conventional speaker wire. Each conductor is composed of 294 strands of the finest copper for superb audio accuracy and flexibility. The Kord Speaker wire is wrapped in ultra flex blue PVC with a black polarity stripe on one side of the round-round cable profile.

Kord Utra Flex Speaker wire is basic side-by-side, oversized speaker cable. Utilizing high strand counts of fine, pure Oxygen Free Copper make the Kord series a very flexible speaker wire. Applications include home and mobile audio. The side by side profile allows for ease of installation under carpets or around base boards. The cable is finished in a translucent matte blue ultra flex PVC jacket and includes a black polarity stripe down one side.

  • Core Material: 36 Gauge Oxygen Free Copper
  • Length: Available in various length
  • Dielectric: Ultra Flex PVC
  • Outer Diameter: 9mm x 4.5mm
  • Max Continuous Length: 1500 Feet

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
