CABLETECH OFC 0.5mm Speaker Cable 100m Bulk Reel

For installers and enthusiasts who demand clean signal transfer without paying for exotic branding, this CABLETECH OFC speaker cable delivers oxygen-free copper conductors in a practical 100-metre reel. Unlike basic copper-clad aluminium wire that can degrade over time, the OFC construction maintains consistent resistance and resists corrosion, ensuring your low-power speaker runs stay reliable for years.

Highlights

• Oxygen-free copper (OFC) conductors for superior conductivity and long-term durability
• 0.5 mm² cross-section per conductor, ideal for low-power home and car audio systems
• Parallel figure-8 configuration with clear PVC jacket and red polarity stripe
• Generous 100-metre bulk reel for custom installations and multi-room projects
• Flexible multi-strand design for easy routing in tight spaces

In daily use

Whether you are wiring a pair of bookshelf speakers, extending car audio lines, or pre-wiring a small commercial space, this cable handles the job without fuss. The transparent jacket lets you inspect the conductors at a glance, while the red stripe on one side eliminates polarity mistakes during installation. Rated for up to 5 A and 50 V, it covers most low-power passive speaker applications with headroom to spare. The reel packaging keeps the cable tangle-free and easy to pull as you work.
