Extron SPK16/1000 (part number 22-151-03) — 1,000 feet of non-plenum 16 AWG speaker cable on a single Extron spool.

SPK 16 sits in the middle of Extron's three bulk speaker gauges, between the 18 AWG and 14 AWG versions, which makes it a common default for general commercial loudspeaker wiring: more copper than the lightest gauge, without the bulk of the heaviest. The construction is one pair of bare copper conductors, and Extron specifies a strand count above what comparable 16 AWG cable offers. In practice that shows up as a cable you route round corners quickly instead of wrestling into place. This part number is the non-plenum build.

Key Capabilities

• One pair of 16 AWG bare copper conductors
• Non-plenum SuperFlex jacket
• Foot-by-foot sequential numbering printed on the jacket
• Extra strands per conductor for easier handling and tighter bends
• 1,000 ft (305 m) spool supplied in a self-dispensing carton
• Plenum version listed separately as Extron SPK16P/1000, part 22-154-03

Where It Is Used

Extron groups it with its Audio, Speaker & Control Cables. It is a frequent specification for training rooms and huddle spaces, divisible meeting rooms, retail and restaurant background audio, auditorium delay speakers, and control room monitoring — wherever the amplifier and the loudspeaker are not in the same rack.
