    In past two years I have made two home theaters in my basement with total of 20 speakers installed (a bit crazy I know but a 7.1 system plus another 7.1.4 takes a lot of speakers and wires.... ). I have bought many different wires from Amazon. Most of them cheap or Amazon best choice etc. I can tell you, this Kord Kable is by far the nicest wire I have used and the price is totally justified by its superior quality. When using the wire one thing immediately stands out to me is that its plastic insulation is so nicely thin and soft, combined with the nature of real copper, making the wire amazingly knot-free and super easy to lay out. Compared to this Kord Kable experience, those cheating CCA wires with thick and hard insulation are absolutely nightmares. Another thing is after striping the wire its copper threads are again so nicely soft and fine, making working with them such a pleasure. In contrast, all the copper threads from those cheap wires are stiff and kind of bristle (probably b/c theyre not real copper, but CCA copper clad aluminum). Huge difference. Dont waste your money ever on those $10/100 ft wires. You only need to spend on wire once and spend dozen bucks more with this quality wire and be done with it. My only regret is why I didnt know this nice wire until last week. Amazon flooded their pages with so many crappy wires that a genuinely good one like Kord Kable is almost impossible to be found. I only heard it by chance when one recommended it on an audio/video forum. If I have one wish that would be that Kord Kable could come with some color variation not jut blue. Itll be nice to color code the wires to different speakers.

    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.

    This is great for surround sound systems. I installed this in mine, easily installed bannana cable ends. Great sound and reliability. I am working on a second room using this cable again.

    Used it to rewire my boat. Stereo sounds killer on very long runs of wire

    This and also the ten guage are the best Ive worked with. I ordered 12 guage from Monoprice and compared to to this, it looked like 20 guage, literally. I have nothing against Monoprice but once you try this stuff, you wont use anything else. I use it for wiring my speakers to my AVR. Its heavy, but strangely the most flexible Ive ever used.

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

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
