What is in the package: 4pcs Banana Female Jack Speaker Binding Post Terminal Connector Review: Worked as they should - Worked perfectly. Easy connection. Review: Quality Speaker Plugs - These plugs are well built from good material. They are of an appropriate size that suits the back terminal connections for speakers. However, these are not screwed types, rather the driver cables have to be soldered at the openings of the plugs. Once soldered, they can easily secured to the back of the speaker crossover board with the supplied washer/nut. The banana plug receptors provide a stable connection with a typical banana plug with a distinctive click. These plugs provide a great value for improving older speaker terminals. If these are being considered for an amplifier output connections, the process may be possible but would be more difficult seeing that the terminal protrusion in the rear is quite short. These are better suited for speaker inputs. ## Features - Made of gold plated metal material, rust and corrosion resistance, pure copper contact material, excellent signal transfer performance. - Colored Code: Banana female socket jack adopting black and red ring for coding, easy to distinguish and recognize. - Application: speaker amplifier line and DIY production. - Easy to Install: Coupler type binding post, screws locking, free-soldering, support bare wire, spades, or banana plugs on either side. - Advantages: oxidation resistance, beautiful appearance, low distortion, excellent signal transfer. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07V4QWXCL | | Best Sellers Rank | #4,220 in Audio & Video Connectors & Adapters | | Customer Reviews | 4.2 4.2 out of 5 stars (112) | | Date First Available | July 12, 2019 | | Item Weight | 1.58 ounces | | Item model number | BJBP-4MM-B2R2 | | Manufacturer | RuiLing | | Package Dimensions | 2.8 x 2.4 x 0.6 inches | ## Images ![4-Pack 4mm Banana Jack Binding Post Gold Plated Female Socket Plug Terminal Connector for Loudspeaker Amplifier (2pcs Red and 2pcs Black Rubber Ring) - Image 1](https://m.media-amazon.com/images/I/612V95Etv2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked as they should *by S***K on May 11, 2025* Worked perfectly.
