Speaker cable Cabletech CCA 2.5 mm, two-conductor black-red

Cabletech speaker cable with CCA conductors and 2.5 mm² cross-section per conductor is designed for connecting speakers and audio equipment in home and small professional AV setups. The cable features two conductors in a black-red jacket to make polarity identification straightforward. The use of copper-clad aluminium (CCA) reduces weight and cost compared with solid copper while maintaining conductivity suitable for short to medium-length speaker runs when installed correctly.

Advantages

The Cabletech CCA 2.5 mm² speaker cable offers a balance of affordability and practical performance for standard audio installations. The two-conductor jacket with color coding simplifies correct speaker polarity connection. The 2.5 mm² cross-section provides low resistance for typical home audio lengths, and the CCA construction makes the cable lightweight and easier to route in tight spaces.

Suitable for

• Connecting bookshelf and floorstanding speakers to amplifiers and receivers in home audio systems
• AV room setups where runs are short to moderate in length
• Multi-room or concealed wiring when a cost-effective, lightweight conductor is preferred

Key specifications

• Conductor material: copper-clad aluminium (CCA)
• Conductor cross-sectional area: 2.5 mm² per conductor
• Number of conductors: two (positive/negative)
• Outer jacket color: black and red for polarity identification
• Intended use: speaker and audio signal connections for short to medium cable runs

How to use

Strip the insulation from each conductor to the required length, taking care not to nick the conductor strands. Observe the black and red jacket colors to maintain correct speaker polarity: connect the red conductor to the amplifier or receiver positive terminal and the black conductor to the negative terminal. Ensure firm, clean terminations using suitable binding posts, banana plugs or spade connectors. Route the cable away from power mains and strong electromagnetic sources to minimise interference. For longer runs or higher power applications, verify that the 2.5 mm² CCA conductor meets required voltage drop and power handling criteria.

Usage recommendations

For optimal performance, use this cable for short to medium speaker runs in home and AV setups. Avoid long high-power runs where low-resistance pure copper conductors are recommended. Secure and protect exposed terminations, and verify polarity at both ends before powering equipment.
