Extron SPK14P/1000 (part number 22-155-03) — the plenum-rated member of Extron's 14 AWG speaker cable family, supplied on a 1,000 foot spool.

Where a loudspeaker run has to cross a space that moves building return air, the jacket has to carry a plenum rating, and that is the whole reason this part number exists alongside 22-152-03. Underneath the jacket the cable is the same electrically: one pair, bare copper, 14 AWG per conductor, with the generous strand count Extron uses across the SPK line so the cable stays workable in the hand. Extron notes that its plenum bulk cable carries North American ratings and is not certified for most of Europe, so confirm approvals before specifying it outside the region.

Key Capabilities

• Plenum-rated SuperFlex jacket for air-handling pathways
• Two 14 AWG bare copper conductors, delivered as a single pair
• Sequential jacket numbering for measuring and cutting on site
• High strand count keeps the cable pliable during long, awkward pulls
• 1,000 ft (305 m) spool packed in a self-dispensing box
• Non-plenum counterpart: Extron SPK14/1000, part number 22-152-03

Where It Is Used

This is the plenum choice for distributed audio above suspended ceilings and through air-return voids: campus and K-12 classroom systems, corporate meeting spaces, healthcare paging, airports and transport hubs, and any commercial fit-out where the authority having jurisdiction requires plenum cable in the ceiling plenum.
