Essentials Basic Banana 2 - Affordable Banana Plug for Speaker Cable

Basic Banana 2 is an affordable, well-made banana plug for speaker cables - a straightforward solution for connecting your cables to the terminals on your system or speakers. The plug ensures a solid connection, yet the cable is easy to disconnect should you need to rearrange your equipment. Despite its simple design, it meets high technical standards.

Key Highlights

• 6-leaf spring contacts of beryllium copper, gold-plated
• Brass body in a durable ABS housing
• Takes cable up to 6 mm² (4.2 mm diameter) - covers every common cable
• Secure clamping with no soldering required

Technology & Benefits

6-Leaf Beryllium Copper Contact

The contact section is built from six spring leaves distributed around the circumference of the pin. Inserted into a terminal, they compress evenly and create a considerably larger contact area than plugs with one or two leaves. Beryllium copper is chosen for its spring properties - it retains elasticity after hundreds of insertions, unlike plain brass, which deforms over time and lets the connection loosen.

Gold Plating Against Oxidation

Gold plating on the contact surfaces prevents oxidation. An oxidised contact gradually increases resistance, which is heard as a loss of detail and dynamics - particularly in systems that sit unused for longer periods.

Solid Connection, Easy Disconnection

The plug holds firmly in the terminal during use but pulls out effortlessly when you need to move speakers or swap components. That's the main advantage of a banana plug over bare wire, which frays on every disconnection and has to be prepared again.

Colour Coding

The plugs come in red and black, making polarity visible at a glance. Out-of-phase wiring is a common mistake when replacing cables and leads to noticeably weaker bass.

Who Is It For?

Basic Banana 2 suits anyone wanting to replace bare wire with a tidy, reliable connection without spending much. The 6 mm² capacity covers all standard speaker cables, and the construction doesn't differ substantially from more expensive models.

Expert Tip from vsystem.bg

Terminals on amplifiers, receivers and speakers are usually secured with small plastic plugs as a safety measure. These need to be pried out with a very small screwdriver or another pointed object before banana plugs can be connected. Before fitting, twist the conductor strands tightly and check that none stray to the side - a single protruding strand bridging positive and negative is the most common cause of a short. If your cable is heavy gauge, measure the bare conductor: anything over 4.2 mm in diameter calls for the Classic Banana 2.

FAQ

How many plugs do I need?
A pair of speakers requires eight - two at each end of both cables. Ordering four red and four black is advisable, so polarity stays clearly marked.

What's the difference from Classic Banana 2?
The construction is similar, but Classic Banana 2 accepts a thicker conductor (8 mm² against 6 mm²), has a more substantial body, and uses 24-karat gold plating.

Why won't the plug go into the terminal?
Most likely the opening is sealed with a plastic plug fitted by the manufacturer. Pry it out with a small screwdriver and the connector will fit without trouble.

Do I need a soldering iron?
No - the conductor is clamped mechanically inside the body of the plug.
