Speaker cable Cabletech OFC 2 mm – oxygen-free copper, 2.0 mm² cross-section

Cabletech OFC 2 mm speaker cable is a twin-conductor audio cable constructed from oxygen-free copper (OFC) with a 2.0 mm² cross-sectional area. It is intended for connecting loudspeakers to amplifiers, receivers and audio processors in home audio, hi‑fi systems and small installations where low resistance and reliable signal transfer are required. The cable's conductors and consistent cross-section support clear mid and low frequency performance and stable impedance across typical domestic speaker runs.

Advantages

The use of oxygen-free copper reduces oxidation and helps maintain low electrical resistance over time, contributing to efficient power delivery to speakers. The 2.0 mm² cross-section offers a balance between flexibility and sufficient conductor area for most residential and small commercial speaker setups. The twin-conductor construction simplifies polarity identification and consistent connections, supporting dependable audio reproduction and minimizing losses on short to moderate cable runs.

Suitable for

• Connecting bookshelf and floorstanding speakers to amplifiers and receivers
• Home theatre and stereo hi‑fi systems
• Multiroom audio installations with moderate cable lengths
• DIY speaker wiring and replacement of existing speaker leads

Key specifications

• Conductor material: oxygen-free copper (OFC)
• Cross-sectional area: 2.0 mm² per conductor
• Configuration: two conductors (stereo speaker cable)
• Typical use: speaker-level audio connections
• Electrical characteristic: low resistance suitable for short to moderate runs

How to use

Strip an appropriate length of insulation from each conductor, taking care not to nick the copper strands. Match polarity between amplifier outputs and speaker inputs by using the cable’s conductor markers or colour-coded insulation. Secure connections using banana plugs, spade lugs or by properly tightening bare-wire terminals, ensuring no stray strands create shorts. Route the cable to avoid tight bends and interference from power cords; for runs through walls or conduits, verify local installation codes and use appropriate protective tubing where required.

Usage recommendations

For optimal performance, keep speaker cable runs as short as practical and avoid bundling with mains power cables. Use 2.0 mm² cable for typical home installations up to moderate lengths; for long runs or systems requiring very high power, evaluate larger cross-sections. Maintain clean, corrosion-free terminations and inspect connections periodically.
