Extron SPK16P/1000 (part number 22-154-03) — plenum-rated 16 AWG Extron speaker cable, 1,000 feet per spool.

Take the standard SPK 16 conductor set — one pair, bare copper, 16 AWG — and put it inside a plenum-rated SuperFlex jacket, and this is the result. It is the part to order when a loudspeaker run passes through a return-air plenum and the inspector will be reading the jacket print. The strand count Extron uses is higher than typical cable of this gauge, which matters more than it sounds when the pull goes through a ceiling grid with limited access. Note Extron's own caution: its plenum bulk cable is rated for North America and is not certified across most of Europe.

Key Capabilities

• Plenum-rated SuperFlex jacket, sequentially numbered
• Two 16 AWG bare copper conductors supplied as one pair
• 1,000 ft (305 m) per spool, in a self-dispensing box
• Elevated strand count for flexibility in confined ceiling work
• Direct non-plenum alternative: Extron SPK16/1000, part 22-151-03

Where It Is Used

Ceiling-speaker distribution in offices and schools, plenum-space runs in healthcare corridors and laboratories, hotel and conference-centre paging, and government or corporate fit-outs where code calls for plenum cable in every air-handling void. Choose it whenever the pathway is a plenum, and use the non-plenum version everywhere else.
