Speaker cable Cabletech CCA 1.5 mm — 2-conductor audio cable for speakers

Cabletech CCA 1.5 mm is a two-conductor speaker cable designed for connecting passive speakers to amplifiers, receivers and audio processors. Each conductor has a 1.5 mm² cross-sectional area and is made of copper-clad aluminum (CCA), offering a lower-cost conductor option compared with pure copper while maintaining acceptable signal transmission for short-to-moderate length runs. The product is intended for wired speaker connections in domestic living rooms, commercial spaces and multi-room audio installations.

Advantages

The Cabletech CCA 1.5 mm speaker cable provides a balance between affordability and functional performance for common audio installations. CCA conductors reduce material cost and weight while preserving adequate conductivity for typical home and light commercial speaker setups. The two-conductor construction simplifies wire management and polarity identification during installation, and the 1.5 mm² cross-section supports typical speaker loads at short to moderate distances.

Suitable for

• Wiring passive bookshelf and satellite speakers in home audio systems
• Connecting in-wall or ceiling speakers for multi-room audio
• Short to moderate length runs between amplifier/receiver and speakers
• Budget-conscious commercial audio installations with moderate power requirements

Key specifications

• Conductor material: copper-clad aluminum (CCA)
• Number of conductors: 2 (bi-wire compatible basic two-core design)
• Conductor cross-sectional area: 1.5 mm² per conductor
• Application: speaker/low-voltage audio signal transmission
• Typical use environment: indoor home and commercial audio installations

How to use

Strip the outer insulation to expose the two conductors, taking care not to nick the metal strands. Identify polarity markers on the cable or the conductor insulation to maintain correct positive and negative connections between the amplifier/receiver and the speaker terminals. Use appropriate connectors (banana plugs, spade lugs) or secure bare-wire terminations at both ends according to the amplifier and speaker terminal types. Ensure solid mechanical connections and avoid sharp bends or kinks that could damage the conductor.

Usage recommendations

For best results, keep cable runs as short as practical for the given installation to minimize resistance and signal loss. Use this CCA cable for low- to moderate-power speaker loads; for high-power or long-distance runs, consider specifying a larger cross-sectional area or a pure copper conductor to reduce energy loss and maintain audio fidelity.
