Speaker cable Cabletech OFC 0.5 mm – two-conductor audio cable

Cabletech OFC 0.5 mm – two-conductor audio cable is a speaker cable with oxygen-free copper (OFC) conductors and a 0.5 mm² cross-section per conductor. It is intended for connecting loudspeakers to amplifiers, receivers and basic public-address systems where short to medium cable runs are required. The cable construction focuses on low-resistance signal transmission and reliable electrical contact for standard home audio and car audio installations.

Advantages

The OFC conductors reduce oxygen-related impurities and improve conductivity compared with standard copper, which helps maintain audio signal integrity over short and medium distances. The two-conductor design simplifies polarity identification and installation when connecting stereo speakers or mono drivers. The 0.5 mm² cross-section offers a compact, flexible cable profile suitable for routing in tight spaces while providing adequate current capacity for low- to moderate-power speaker systems.

Suitable for

• Connecting bookshelf or small floorstanding speakers to home amplifiers and receivers
• Car audio speaker connections for rear or front door speakers where runs are not long
• Simple PA or public-address setups with low-power drivers and short cable lengths
• DIY audio projects and speaker repair where compact cable and clear polarity are needed

Key specifications

• Conductor material: Oxygen-free copper (OFC)
• Conductor cross-section: 0.5 mm² per conductor
• Number of conductors: Two (positive and negative)
• Application: Speaker-level audio connections for home, car and basic PA systems
• Cable profile: Flexible, compact jacket suitable for short to medium runs

How to use

Strip an appropriate length of insulation from each conductor and ensure clear identification of polarity before making connections to speaker terminals and amplifier outputs. Maintain secure mechanical and electrical contact by using banana plugs, spade terminals, or well-twisted bare wire connections depending on the terminal type. Keep cable runs as short and direct as practical to minimize resistance and potential signal loss; avoid tight bends and kinks that could damage the conductor or insulation.

Usage recommendations

For best performance with the 0.5 mm² Cabletech OFC speaker cable, use it in short to medium length runs and pair it with low- to moderate-power speakers. When installing in vehicles or behind walls, ensure the jacket material and installation environment match local safety and fire regulations. If higher power handling or longer runs are required, consider a cable with larger conductor cross-section.
