Monoprice Nimbus Series 18 AWG 4-Conductor CMP-Rated Speaker Wire - 1000 ft

Nimbus Series 18AWG 4-Conductor CMP-Rated Speaker Wire

Experience high-fidelity audio connectivity with Monoprice's Nimbus Series, designed for professional installations where safety and performance matter. The cable combines 100 percent copper conductors with a durable plenum-rated jacket, ready to endure the demands of duct runs and ceiling spaces.

The 1000-foot spool offers practical bulk cabling for longer runs, reducing the need for frequent joins while maintaining consistent signal quality across rooms or auditoriums.

Built with an 18 AWG gauge, the four-conductor layout preserves signal integrity for longer runs, while its oxygen-free copper ensures minimal resistance and robust signal performance across channels.

Why CMP rating matters

• UL CMP-rated jacket supports use in plenum spaces, aligning with building safety standards.
• External jacket is treated to resist the spread of fire, contributing to safer routing in ducts and airspaces.
• 100% pure bare copper conductors deliver faithful, low-impedance transmission for clear sound.
• Color-coded conductors help installers quickly identify paths and maintain clean wiring layouts.
• Versatility in connection: the 2-conductor path serves a single speaker, while the 4-conductor option supports stereo pairs.
• Lifetime warranty on all cables provides ongoing coverage for confidence in performance.

Practical uses and setup ideas

• Ideal for commercial auditoriums, conference rooms, and classrooms with ceiling plenums.
• Great for home theater setups where long cable runs are needed behind walls or under floors.
• Suitable for installations that require compliance with fire-safety codes while preserving audio fidelity.

In short, Nimbus Series wire combines safety, reliability, and acoustic clarity in a single bulk-spool solution. While performance can vary with system components and room acoustics, this cable offers flexible options for both simple and more complex audio layouts.
