Details
Extron SPK 18 Plenum (part number 22-153-02) — plenum-rated 18 AWG Extron speaker cable, listed here on a 500 foot (152 m) spool.
When a distributed audio design puts dozens of small speaker drops above a suspended ceiling, two things matter: the cable has to be light enough to manage in quantity, and its jacket has to satisfy the plenum rule for return-air voids. This part number answers both. The conductors follow the SPK pattern — one pair, bare copper, 18 AWG — with the raised strand count Extron uses so the cable stays pliable. Extron's own guidance is that its plenum bulk cable is rated for North America and is not certified across most of Europe.
Key Capabilities
- Plenum-rated SuperFlex jacket for return-air ceiling spaces
- Two 18 AWG bare copper conductors, supplied as one pair
- Sequential numbering along the jacket for on-site measuring
- Listed as a 500 ft (152 m) spool instead of the full 1,000 foot reel
- Extron's current SPK 18 plenum listing is SPK18P/1000, part 22-153-03
Where It Is Used
Ceiling loudspeaker networks in corporate offices, schools and universities, healthcare paging and sound masking, hospitality and retail music systems, and transport terminals — wherever the run crosses an air-handling void and code calls for a plenum-rated jacket.

Availability note: Extron's live SPK 18 part number table shows only 1,000 foot spools, so this 500 foot plenum put-up is a legacy configuration — confirm with Ampronix before ordering.
