"They were the only business that had exactly what I wanted at a reasonable price. It shipped immediately and works well."



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.

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

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...
