Speaker cable electro base PBA50-RB-CTECH 2x0.50 mm² copper red/black

Speaker cable electro base PBA50-RB-CTECH features two flexible copper conductors with a cross-section of 0.50 mm², color-coded red and black to indicate polarity. The cable is designed for connecting loudspeakers and audio equipment in domestic, studio, or fixed installation environments. Flexible copper strands provide consistent signal transmission while simplifying routing in tight spaces; visible color coding reduces the risk of wiring errors during setup.

Advantages

The twin-conductor design with red and black insulation makes polarity identification straightforward. Copper conductors deliver reliable electrical conductivity for audio signals and maintain flexibility for easy handling and installation. The compact cross-section is suitable for short to medium runs where space and neatness are priorities, and the cable construction supports straightforward termination with common speaker connectors or direct binding posts.

Suitable for

• Home stereo speaker connections
• Small studio monitoring setups
• Fixed installations in walls or cabinets where space is limited
• Portable audio systems and PA speaker wiring for short runs

Key specifications

• Conductor material: copper
• Number of conductors: 2 (paired)
• Conductor cross-section: 0.50 mm² (per conductor)
• Insulation colors: red and black for polarity identification
• Construction: flexible stranded conductors suitable for routing

How to use

Strip a small length of insulation from each conductor to expose the copper strands, taking care not to cut the strands. Connect the red conductor to the positive terminal and the black conductor to the negative terminal on both the amplifier and the speaker to maintain correct polarity. For secure connections, twist the exposed strands and insert into screw terminals, spring clips, or crimp/banana connector assemblies as required by the equipment. Route the cable to avoid sharp bends and sources of electromagnetic interference.

Usage recommendations

For optimal performance, use this cable for short to medium-length speaker runs and verify polarity before finalizing installations. When running cables through walls or conduits, ensure compliance with local building regulations and consider using additional protective conduit or sheathing where mechanical protection is required.
