"Ordering process was easy and product arrived faster than I had expected. Thanks."



While high performance speakers are one of the most important elements in your home theater or music system, to get the most out of your speakers, high quality speaker wire is essential. Thanks to Silverback Speaker Wire, audiophile sound quality is now easier than ever to achieve.


  • Extended frequency response, wide dynamic range, precise imaging, and greater clarity
  • High strand count (over 2.5 times more than most 12 AWG speaker wire)
  • Pure copper conductors
  • Oxygen free
  • Precision 24k gold contact connectors for superior signal pass-through

Highest strand count

Silverback speaker wire was developed with the highest quality standards in mind. Most 12 AWG speaker cables use 90 to 100 threads of copper, we’ve put 259 strands into each conductor of our Silverback cable. This allows for less distortion, deeper bass, better imaging, and cleaner highs from your sound system.

Pure, oxygen-free copper

Not only does Silverback speaker wire have a higher strand count, it is also made up of pure, oxygen-free copper. Cheaper speaker cables have other alloys mixed with the copper in the conductors. This makes the cable cheaper, but also reduces the quality of the sound. Air pockets in the copper can also reduce sound quality and can even ruin the cable over time.

Silverback banana plugs for the best connection

Our pre-terminated cables come with Silverback banana plugs, giving you the easiest and best possible connection. These precision 24 k gold connectors have a pure copper core for perfect signal pass-through. They also feature double screws, which when fastened, are just as effective as soldering while making them removable as well.

Pros: Easy to install. Handsome...After a few I find gthem very smooth and full sounding across the audio spectrum ...Makes cable choosing simple- a no risk choice.

Cons: none

Other: These replace a set of Monster 12 gauge cable(to be fair 20 years old) Remarkable change...simply the best $20 i have spend on audio in 15 years. I use planer speakers which afre very detailed...

Pros: Well Built, Great "Professional" look.

Cons: None.

Other: I spent a lot of time and money on my media plugs,caps and fixtures and wanted NO part of seeing simple clear speaker wire coming out of of the wall from my nice banana plug switch plate, like we all had when we were kids. Everyone told me that was my only alternative. So Glad I found this site, and this product. It really gives my wall jacks a professionally finished look.

I have used many brands of speaker wire before but none come close to quality and value of this Silverback.

Fantastic convenience!

The 50 foot cable was a life saver for me to maintain the integrity of the system I have in my home. I have used various pre-manufactured Sewell speaker wire, and I found it necessary to relocate my component rack and the ability to order a 50 foot sire saved me. Fantastic service from this company. Exceptional quality. Great price. Thank you.
