SCP 12/2OFCTC-HD-WTD — ProSeries indoor/outdoor 12 AWG speaker cable
The SCP 12/2OFCTC-HD-WTD is a ProSeries 2-conductor 12 AWG speaker cable engineered for both indoor and outdoor permanent installations in residential and commercial audio systems. Featuring 65-strand oxygen-free tinned copper conductors, it delivers excellent conductivity with superior corrosion resistance — ideal for outdoor environments, marine applications, or anywhere long-term moisture exposure is a concern. The UV-resistant Heavy-Duty PVC jacket allows seamless transitions between indoor riser runs and exterior installations without cable changes at the threshold. Rated UL CMR (riser) in North America and EN50575 EuroClass Dca in Europe, it satisfies compliance requirements across both markets. Supplied in a 500 ft/152 m reel-in-box.
Tinned OFC Conductors Resist Corrosion
The conductors are oxygen-free copper with an additional tin coating applied to each strand. OFC alone maximises signal purity by eliminating the micro-oxidation that degrades bare copper over time; the tinning layer takes this further by forming a physical barrier against moisture ingress and chemical corrosion. In practice this means speaker circuits routed through damp wall cavities, under roof eaves, around pool enclosures or in outdoor landscape systems stay low-resistance and sonically transparent for the lifetime of the installation — without the greenish oxidation and elevated contact resistance that eventually shows up in untinned cables.
Dual-Market Compliance: UL CMR + EN50575 Dca
This cable carries UL CMR (cUL FT4) riser approval for North American in-wall vertical runs and simultaneously meets EN50575 EuroClass Dca-s3,d2,a3 for European CPR compliance. Carrying both ratings on a single SKU eliminates the need to stock separate cables for NA and EMEA projects, simplifies procurement for integrators working across both markets, and satisfies building inspectors and project spec sheets without substitutions. The NEC CL3R/CL2R 75 °C rating further confirms suitability for Class 2 and Class 3 in-wall signalling circuits.
UV-Resistant HD PVC Jacket for Outdoor Runs
The heavy-duty PVC jacket is specifically compounded for UV sunlight resistance, allowing the cable to be routed in exposed outdoor locations — along exterior walls, across rooftops, under eaves or in conduit runs above grade — without the jacket becoming brittle, cracking or discolouring over years of sun exposure. This removes the usual boundary between the indoor riser section and the outdoor segment: a single continuous cable can transition through the wall and continue outdoors, reducing connectors, junction boxes and potential failure points in the signal path.
High Strand Count for Flexibility and Easy Pulling
With 65 individual strands per conductor (each 0.254 mm), the cable achieves a flexible, pliable feel that pulls smoothly through conduit, around bends and through tight wall cavities — far easier than a lower-strand-count cable of the same AWG. The nylon rip cord built into the jacket allows clean, tool-free opening of the outer sheath for mid-run taps or termination, and the twisted-pair construction (40 mm lay length) keeps the two conductors geometrically stable and reduces susceptibility to induced hum from nearby mains wiring.
Reel-in-Box with Recyclable Packaging
The 500 ft/152 m length is wound on a reel enclosed in a pull-out cardboard box with no plastic components — the box itself acts as a dispenser, allowing tangle-free payout on the job site without an additional cable reel stand. The recyclable-materials construction aligns with green-building and LEED documentation requirements where packaging waste tracking is needed. Box dimensions are 310 × 340 × 350 mm and the packed weight is approximately 19 kg, making it straightforward to specify freight costs and van stocking.
