SCP 16/2OFCTC-HD-BKD — ProSeries tinned copper indoor/outdoor speaker cable
The SCP 16/2OFCTC-HD-BKD is a ProSeries 2-conductor 16 AWG speaker cable engineered for professional commercial and residential audio installations that span indoor and outdoor environments. Its oxygen-free copper (OFC) conductors are tin-coated for superior corrosion resistance, making the cable well suited for permanent and semi-permanent runs exposed to moisture, humidity, or direct sunlight. Rated UL CMR for in-wall riser applications in North America and carrying the European EN50575 Dca EuroClass fire-performance rating, the cable meets the compliance requirements of both markets. Packaged in a tangle-free Reelex II box for easy, waste-free pull-outs on the job site, and backed by a Limited Lifetime Warranty.
Tinned OFC Conductors Fight Corrosion
Standard bare copper oxidises over time when exposed to moisture or humidity, degrading conductivity and audio quality. This cable uses oxygen-free copper stranded at 65×0.16 mm and then tin-coated, creating a protective barrier that holds up in damp enclosures, outdoor speaker runs, or coastal environments where salt air accelerates oxidation. For end users, this translates to stable, low-resistance connections that maintain audio fidelity years after installation — with far fewer service calls caused by gradually deteriorating joints.
North American & European Compliance in One SKU
The cable carries UL CMR (riser) and cUL FT4 ratings for in-wall runs in North America, and simultaneously holds EN50575 EuroClass Dca-s3,d2,a3 for the EU and EMEA markets. Having a single cable that satisfies both regulatory frameworks simplifies procurement and inventory for integrators working across markets or supplying multi-national clients. On the project side, the Dca fire class means the cable meets building regulation requirements in most European countries without needing a separate LSZH or plenum substitute.
UV-Resistant Jacket for True Outdoor Runs
The heavy-duty PVC jacket is specifically formulated to resist UV degradation, allowing the cable to be routed externally — along building façades, under eaves, or between outdoor speaker positions — without the jacket becoming brittle or cracking from prolonged sun exposure. The operating temperature range of −20 °C to +75 °C covers both cold climates and sun-heated conduit. This removes the need for separate outdoor-rated conduit protection in most standard outdoor speaker installations, reducing material cost and installation time.
Twisted-Pair Construction Reduces Noise
The two insulated conductors are twisted at 38 twists per metre (26 mm lay length), which provides inherent noise rejection by cancelling common-mode interference induced along the run. In commercial environments with dense power wiring, LED drivers, or AV switching equipment nearby, this matters: untwisted cables can pick up hum or RF interference that degrades background music or paging systems. The twist also keeps the pair geometry consistent, resulting in stable 85 Ω impedance and predictable capacitance (80 pF/m) over long runs.
Reelex II Box for Faster, Cleaner Pulls
The cable ships in a Reelex II tangle-free pull box, which dispenses from the inside of the coil rather than the outside. This eliminates the kinking, looping, and re-coiling that slows down conventional drum or figure-eight packaged cable. Installers can set the box anywhere on site and pull directly into conduit, raceway, or wall cavity without a second person managing the spool. Reduced handling time per pull is meaningful on larger projects with many speaker drops.
