SCP 14/2OFCTC-HD-BKD — ProSeries tinned copper indoor/outdoor speaker cable
The SCP 14/2OFCTC-HD-BKD is a ProSeries 2-conductor 14 AWG indoor/outdoor speaker cable designed for commercial and residential audio installations. Built with 105-strand oxygen-free tinned copper conductors and a UV-resistant HD PVC jacket, it is suited for permanent in-wall riser runs, outdoor environments, home theater, and semi-permanent speaker deployments. Dual compliance with North American UL CMR (riser) and European EN50575 Dca-s3,d2,a3 (CPR) ratings makes it a go-to choice for integrators working across both markets. The twisted-pair construction minimises interference, and the cable ships in a convenient tangle-free Reelex II box.
Tinned OFC for Corrosion-Free Longevity
The conductors are made from 105-strand oxygen-free copper with a tin coating applied to every strand. OFC minimises resistive losses versus standard copper, while the tin layer acts as a corrosion barrier, preventing oxidation caused by moisture, humidity, and the chlorides found in coastal or outdoor environments. In practice this means speaker connections maintain low resistance and consistent audio fidelity over the full lifetime of the installation — even when the cable passes through a wall cavity into an exposed outdoor soffit or patio area, where plain copper would gradually degrade.
True Indoor/Outdoor UV-Resistant Jacket
The HD PVC outer jacket is compounded to resist UV radiation, allowing the cable to be used in direct sunlight without brittleness or cracking over time. This single-cable approach lets installers run from an indoor amplifier rack through a wall penetration to an outdoor speaker location without needing to transition to a separate outdoor-rated cable at the wall exit — reducing junction points, labour time, and potential failure points. The cable is also rated for operation from -20°C to 75°C, covering the temperature swings seen in most climates.
Dual-Standard Compliance: UL CMR + EN50575 Dca
This cable carries both a North American UL CMR (riser) / NEC CL3R/CL2R rating and a European EN50575 EuroClass Dca-s3,d2,a3 CPR rating, backed by a Declaration of Performance (DoP). The Dca rating confirms the cable meets defined fire performance criteria required for distribution in EU member states after the Construction Products Regulation. For integrators supplying both US and European projects — or distributors stocking a single SKU for multiple markets — this eliminates the need to hold separate cable products for each regulatory region, streamlining procurement and inventory.
Reelex II Tangle-Free Packaging
The 500ft (152m) length is wound using Reelex II figure-8 technology, which pays out from the centre of the box without tangling or kinking. On a typical installation job this saves meaningful time compared to a traditional spool, since one person can pull cable smoothly through conduit or ceiling spaces without a second person holding a reel. The box also acts as a dispenser that can be set on the floor, reducing trip hazards and keeping the unused cable clean during the pull.
