"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: Quality construction, works as described.

Cons: None that I can see so far.

Other: Should have ability to ship order via UPS vs USPS. USPS sent package to East coast and it sat in Mass. for over 7 days before USPS finally decided to ship it to Oregon. Took 2 weeks to get order vs the 2 days it should have taken from Utah to Oregon by priority mail. Not blaming the manufacturer, just the lousy USPS.

Pros: Great and detailed sound transmission, excellent wire quality and open sound. Presentation is very good but I would love a different, more modern color. Black and gray are death colors.

Cons: NO CONS but better quality banana connectors and the addition of spade option would make them to the top

Other: Great company, ownership and service. Thank you

What can I say but this is the BEST speaker wire I've ever used... and I've tried many! Monster, Monoprice, Knu, Blue Jean all pale in comparison to the cost/value ratio you get with Sewell Silverback.

These Silverback Speaker Cables are outstanding. Quality of all components are excellent. Much better than others that claim better quality ( for a price ).
