Silverback connectors have the quality you’ve come to expect from Sewell, including gold plated connectors and a heavy-duty casing. What sets Silverbacks apart is the unique dual-screw lock design. This connection will secure your cable more than a single-screw or open-screw design. Dual-screw connectivity provides a secure connection, durability, and a clear signal transmission through the added contact. Silverback Flex Pin connectors accommodate up to 10 AWG speaker wire.

Bare wire connections tend to get pulled out or frizzy after time passes, are prone to corrosion.  The Flex Pin connections solve these problems with a connector that is corrosion resistant and won't fray or break.


How to Install Silverback Banana Plugs:

  1. Unscrew the jacket to reveal the core of the Silverback Banana Plug.
  2. Loosen the two small screws to accomodate the size of your speaker wire.
  3. Feed the speaker wire into the core of the banana plug.
  4. Tighten the screws to secure the speaker wire.
  5. Replace the jacket over the core.

Sewell Silverback Flex Connectors

The Silverback Flex Pins are for inputs that are spring-loaded or simply accept a wire-only connection. The Silverback Flex Pins marry the beautiful and sturdy design of the Silverback Banana plug, with the need for wire connection. We’ve developed a special non-conductive coating for our aluminum casing on the Silverback, which will protect the plugs from electrical conductivity, with no worries of shorting your speakers.

Perfect solution

Exactly what you need for high gauge speaker wire into a spring-loaded receiver.

Silverback flex pin connectors

Definitely a reliable improvement over bare wire. Strongly recommended.

Speaker connectors

Haven't actually used the connectors yet. Waiting for new receiver to arrive, but I think they will definitely work out fine. They seem to be made well. Will update after the receiver arrives.

Working ok so far

The connectors are working ok so far. I’ve never used this type until now. The method of connecting the speaker wire seems primitive, but maybe that’s the industry standard. Appears to be well made.

Good quality for the money.

These are pretty good. Nice and sturdy, well made. The only thing that kept me from giving them five stars is that the barrels are live, and need to be insulated if used on vintage gear with closely spaced speaker terminals.
