OFC Sounds Better!

FS Cables have a great choice of OFC speaker cables from the TruSound Professional range of high-performance audio cables. Featuring stranded OFC (oxygen-free copper, ultra-high purity 99.995%) conductors, the cables combine flexibility with optimum levels of performance and sound quality. They are available in 12, 14 and 16 gauge with distinctive PVC or LSHF jacket colours – pink or violet – for easy identification once installed. 

These speaker cables are ideal for commercial installations in home cinemas, pubs, clubs, gyms, and other venues. The LSHF (low smoke halogen free) version is ideal for public buildings where evacuation in the event of fire may be a priority. There are also Duct Grade/Outdoor and Weatherproof options for external applications and direct burial. The Weatherproof versions utilise a clever gel tape that remains dry until exposed to water when it swells to form a water barrier. This prevents any mess during termination normally associated with petroleum gel-filled cables. 

By specifying TruSound Professional audio cable you can be sure you are using cables of the highest quality and construction. The TruSound range also includes parallel and round multicore speaker cables in various sizes and core configurations. Cables are stocked in 100m, 200m, and 500m reels for next-working-day delivery. A ‘cut-to-length’ service is also offered, reducing both your costs and wastage.

Did you know?

OFC stands for Oxygen Free Copper, which is a grade given to copper with less than 0.001% oxygen. This is done to remove impurities in the copper and allow electrons to travel with less resistance, meaning more conductivity and better sound quality. OFC also runs cooler, is more durable, resists shorts and corrosion, and performs better in longer cable runs. 

The process of producing oxygen free copper begins with separating the copper mineral from the ore by crushing the ore into a fine powder and then melting it in a furnace. Impurities are extracted either by oxidizing to vapor or adding fluxes to form slag, which is later removed. Copper castings resulting from that process are then melted and cast in a vacuum, reducing environment, or inert gas atmosphere to produce very pure copper with negligible oxygen content.
