Extron SPK14/1000 (part number 22-152-03) — a 1,000 foot non-plenum spool of Extron's 14 AWG bulk loudspeaker cable.

This is the wire that carries audio from an amplifier rack out to the loudspeakers. Extron builds the SPK 14 around a single pair of bare copper conductors at 14 AWG, the largest conductor size in the SPK bulk speaker range. What separates it from ordinary cable of the same gauge is the strand count: Extron packs more individual strands into each conductor, and the result is a cable that takes a bend without fighting back. Installers feel that on long pulls. This particular part number is the non-plenum version, intended for pathways that are not shared with building return air.

Key Capabilities

• One pair of bare copper conductors, 14 AWG each
• SuperFlex jacket in the non-plenum construction
• Sequential numbers printed down the jacket, so remaining footage reads at a glance
• Raised strand count for flexibility through conduit, trays and tight ceiling voids
• 1,000 ft (305 m) wound on a spool and packed in a self-dispensing carton
• Plenum sibling: Extron SPK14P/1000, part number 22-155-03

Where It Is Used

Extron files this cable under Audio, Speaker & Control Cables within its bulk cables and connectors range. Typical homes for it are lecture halls and classrooms, boardroom and conference audio, paging and background music in retail or hospitality, houses of worship, and command or control rooms where amplifier racks sit well away from the speakers they feed.
