Speaker cable Lexton 2×2.50 mm² CCA, black/red - LXK620

Lexton 2×2.50 mm² CCA speaker cable LXK620 is a twin-core audio cable with two 2.50 mm² conductors made from copper-clad aluminium (CCA), finished in black and red for polarity identification. Intended for loudspeaker and audio-system connections, this cable offers a budget-conscious option for home audio, studio setups and fixed installations where moderate power transmission and clear signal transfer are required. The conductor is copper-plated with high-purity oxygen-free copper (OFC) to improve corrosion resistance and reduce contact losses compared with unplated aluminium.

Advantages

The Lexton LXK620 combines the lower weight and cost advantages of aluminium-based conductors with a copper plating that increases resistance to oxidation and helps maintain low electrical resistance. With a conductor cross-section of 2.50 mm² per core, the cable supports typical domestic and small-studio loudspeaker loads while keeping voltage drop and power loss at acceptable levels for moderate cable runs. Color-coded insulation (black/red) simplifies correct polarity connections during installation.

Suitable for

• Connecting passive loudspeakers to amplifiers in home audio systems
• Small recording or rehearsal studio speaker wiring
• Fixed installations in halls, classrooms or meeting rooms where moderate power is required
• Multi-room audio zones with runs of moderate length

Key specifications

• Conductor type: copper-clad aluminium (CCA) with high-purity copper plating
• Configuration: twin-core (2 conductors)
• Conductor cross-section: 2.50 mm² per core
• Length: 100 m (spool)
• Insulation colors: black and red for polarity identification
• Recommended application: loudspeaker and general audio signal connections

How to use

Strip the insulation carefully to expose the conductor without nicking the copper plating, then connect the cores to the speaker and amplifier terminals observing correct polarity (red = positive, black = negative). For reliability, use secure screw, spring or binding-post connections and avoid loose or frayed strands. Route the cable to minimise sharp bends and avoid running parallel to mains power cables to reduce electromagnetic interference. For long runs consider amplifier power and speaker sensitivity to ensure adequate volume and sound quality.

Usage recommendations

Use this cable for moderate-length speaker runs and standard domestic or light professional installations. For very long runs, high-power systems, or installations demanding the lowest possible resistance, consider using larger cross-section conductors or pure oxygen-free copper (OFC) cable. Regularly inspect connections for corrosion or loosened terminals and maintain clear polarity to preserve audio quality.
