Speaker cable Cabletech 1.5 mm², two-conductor, black-red, stranded copper

Cabletech speaker cable with a 1.5 mm² cross-sectional area per conductor is a two-conductor audio cable designed for reliable signal transfer between amplifiers and loudspeakers. The cable features stranded copper conductors in two distinct insulation colors (black and red) to simplify polarity identification for left/right or positive/negative connections. Its flexibility and conductor size make it suitable for home audio systems, car audio installations, and modest public address runs where moderate power handling and ease of routing are required.

Advantages

The stranded copper construction provides improved flexibility compared with solid conductors, facilitating neat routing through tight spaces and around bends. Color-coded insulation reduces wiring errors and speeds installation, while the 1.5 mm² conductor area offers a balance between conductivity and manageability for short-to-medium length speaker runs. The cable's design is compatible with a wide range of speaker terminals and binding posts commonly used in residential and automotive audio setups.

Suitable for

• Connecting bookshelf or floorstanding speakers to home amplifiers/receivers
• Car audio speaker wiring where flexible cable is required
• Small public address speaker runs and commercial background audio
• In-wall or concealed installations when advised gauge supports the power level

Key specifications

• Conductor type: stranded copper
• Number of conductors: two (bi-wire for polarity)
• Conductor cross-sectional area: 1.5 mm² per conductor
• Insulation colors: black and red for polarity identification
• Application: speaker/low-voltage audio connections

How to use

Strip an appropriate length of insulation from each conductor, taking care not to nick the copper strands. Match the red and black conductors to the corresponding positive and negative terminals on the amplifier and speaker, observing consistent polarity to maintain correct phase. For exposed ends, twist strands tightly or use appropriate crimp ferrules/banana plugs to improve contact and prevent stray strands. Keep cable runs as short as practical to minimise losses; for longer runs, consider larger conductor cross-sections. When routing through walls or vehicle panels, follow applicable building and automotive regulations and use grommets where necessary to protect the insulation.

Usage recommendations

For typical home audio and car installations, use this 1.5 mm² Cabletech speaker cable for runs up to moderate lengths; for higher power applications or long-distance runs, evaluate larger cross-sections to reduce resistance and maintain audio fidelity. Ensure secure termination at binding posts or connectors and avoid tight kinks that could damage the stranded conductors.
