Voltive 14/2 Plenum Speaker Wire 500ft Box - Plenum Rated OFC

In this review the Voltive 14/2 Plenum Speaker Wire is evaluated for installers and homeowners who need a reliable, fire-safe 14 gauge speaker cable in bulk. The bottom line: this is a workhorse cable built with oxygen-free copper and a plenum (CL3P) rating, packaged in a 500 ft box designed to reduce tangles and speed installation. It suits anyone running low-voltage audio, LED lighting, or alarm wiring where plenum fire-safety and signal integrity matter most.

Key Features

• 14 AWG, 2 conductors: Provides a balance of flexibility and conductivity for short to medium-length speaker runs and other low-voltage circuits.
• Oxygen-free copper (OFC): The 41-strand OFC conductors reduce signal loss compared with CCA alternatives and improve long-term durability.
• CL3P plenum rating: Fire-safety rated for use in walls, risers and plenums, making it suitable for both commercial and residential installations requiring plenum-rated cable.
• 500 ft bulk box: Large payout box with patented winding and a payout hole minimizes kinks and tangles during pulls and keeps the job moving.
• Time-saving jacket features: Ripcord, foot markers and printed UL/reorder info on the jacket speed identification and termination on the job.

Who It's For

The Voltive 14/2 Plenum Speaker Wire is aimed at professional installers, AV integrators and serious DIYers who need plenum-rated 14 gauge stranded cable in larger quantities for multi-room audio, in-ceiling or in-wall runs, LED lighting and low-voltage security systems. The OFC conductors are a draw for anyone wanting better signal retention than copper-clad options.

It is not intended for high-power long-distance runs where heavier gauge cable is required, nor for buyers who only need a few feet of speaker wire; those users should consider shorter sample lengths or thicker gauges for extended runs.

Pros & Cons

Pros

• Plenum CL3P rating and UL listing provide peace of mind for in-wall and plenum installs.
• Oxygen-free copper 41-strand conductors offer lower loss and improved durability over CCA wires.
• 500 ft box with patented winding, payout hole and reinforced handles reduces installation time and cable damage.
• Jacket ripcord and printed foot markers make identification and termination easier on site.

Cons

• The 14 AWG size is not ideal for very long speaker runs or very high-power systems where thicker cable is advisable.

Our Verdict

The Voltive 14/2 Plenum Speaker Wire is a practical, value-oriented choice for installers who need a large quantity of plenum-rated 14 AWG cable with quality OFC conductors and a jobsite-friendly box. It combines fire-safety certification, better-than-CCA copper, and time-saving packaging features, making it a solid pick for most in-wall and plenum low-voltage installs where 14 gauge is appropriate.

Frequently Asked Questions

Is this cable safe for plenum spaces?
Yes. The cable carries a CL3P plenum rating and is UL listed for installation in plenums, risers and walls.

Are the conductors solid or stranded?
The conductors are stranded, specifically 41-strand oxygen-free copper for improved flexibility and conductivity.

Can I use this for long speaker runs?
For very long runs or very high-power systems, a thicker gauge than 14 AWG is recommended; this cable is best for short to medium-length runs.
