Speaker cable Cabletech OFC 1.0 mm, oxygen-free copper conductor, twin core for audio connections

Cabletech OFC 1.0 mm speaker cable is a twin-core audio cable with oxygen-free copper conductors and a 1.0 mm² cross-section per conductor. It is designed for connecting loudspeakers to amplifiers or receivers and provides a low-resistance path for audio signals. The cable combines moderate gauge and flexibility to suit home audio systems, bookshelf speakers and car audio installations where a reliable, straightforward speaker connection is required.

Advantages

The oxygen-free copper (OFC) conductors reduce oxidation and help maintain consistent conductivity over time. Twin-core construction simplifies polarity identification during installation. With a 1.0 mm² cross-section per conductor the cable balances electrical performance with pliability, making routing and placement easier in confined spaces. The cable is suitable for short to medium-length speaker runs where a moderate gauge is adequate for maintaining sound quality.

Suitable for

• Connecting bookshelf or satellite speakers to home stereo amplifiers and receivers
• Short to medium-length speaker runs in living rooms and home theaters
• Car audio speaker connections where moderate gauge and flexibility are needed
• DIY speaker projects and retrofitting existing installations

Key specifications

• Conductor material: Oxygen-free copper (OFC)
• Conductor cross-section: 1.0 mm² per conductor
• Configuration: Twin-core (two conductors)
• Intended use: Speaker / audio connections
• Flexibility: Moderate, suitable for routing in confined spaces

How to use

Strip a short length of insulation from each conductor at both ends, taking care not to nick the copper. Maintain correct polarity by observing the cable marking or color on one conductor and connect positive to positive and negative to negative on amplifier and speaker terminals. For bare wire terminations twist the conductor strands firmly before insertion; alternatively use crimped banana plugs or spade connectors to improve mechanical connection and reduce the risk of stray strands. Route the cable away from mains power lines to minimize interference and secure it with clips or cable ties as needed.

Usage recommendations

Use this 1.0 mm² OFC speaker cable for short to medium runs where a balance of conductivity and flexibility is required. For long runs or high-power applications consider a thicker conductor to reduce voltage drop. Keep connections tight and protected from corrosion for reliable long-term performance.
