Liberty AV 1000' Black Commercial Grade General Purpose 14 AWG 2-Conductor Cable Reel - 14-2C-BLK

Product Overview

The Liberty AV 14-2C-BLK is a 1000ft reel of 14 AWG 2-conductor commercial-grade general-purpose speaker cable rated CL3R under NEC and CMG under CEC, suitable for riser and in-wall audio distribution runs in commercial AV installations. Constructed with stranded annealed bare copper conductors and a riser-rated PVC jacket, this 2-conductor cable is designed for amplifier output wiring, 70V distributed speaker systems, and class 2/3 low-voltage power runs in environments where a non-plenum riser rating satisfies code. The black jacket identifies it as a standard riser-rated product within mixed-cable commercial AV infrastructure.

Product Description

The 14-2C-BLK is Liberty AV's commercial-grade 2-conductor speaker cable at 14 AWG, built for audio integrators and contractors deploying distributed audio systems in commercial buildings, retail spaces, houses of worship, and multi-purpose AV environments. The stranded annealed bare copper conductors provide flexibility for routing through walls, conduit, and cable management systems while maintaining low DC resistance for efficient power transfer from commercial amplifiers to speaker loads.

At 14 AWG, this cable is appropriate for distributed speaker runs exceeding the practical range of 16 AWG, particularly in larger commercial spaces where amplifier-to-speaker runs may extend 50–200ft or more. It is suitable for 4-ohm, 8-ohm, and 70V/100V distributed audio topologies. The twisted, unshielded construction provides basic common-mode noise rejection sufficient for speaker-level signals. The semi-rigid PVC insulation and riser-rated PVC jacket satisfy NEC CL3R requirements for in-wall runs between floors in non-plenum riser spaces. For applications requiring AV cable runs in air-handling plenum spaces, the plenum-rated version should be used instead. This 1000ft reel format minimizes per-unit cost on multi-zone audio installations and bulk commercial cabling pulls.

Key Features

• 14 AWG Stranded Annealed Bare Copper — Stranded construction balances flexibility for routing with low resistance for efficient speaker-level power delivery over longer commercial AV runs.
• CL3R / CMG Riser Rated — NEC CL3R and CEC CMG rated for in-wall installation in vertical riser spaces between floors, satisfying building code without conduit in qualifying non-plenum applications.
• Twisted, Unshielded Construction — Twisted pair geometry provides basic common-mode rejection adequate for speaker-level signal distribution without the added cost and bulk of a shield.
• Semi-Rigid PVC Insulation — Maintains conductor separation and insulation integrity across standard commercial building temperature ranges.
• Riser-Rated PVC Jacket — Flame-rated outer jacket satisfies NEC Article 820 and UL 1666 riser flame propagation requirements for vertical in-wall runs.
• 70V Distribution Compatible — 14 AWG conductor size is appropriate for 70V constant-voltage distributed speaker systems in commercial AV applications including retail, corporate, and educational environments.
• 1000ft Reel Format — Full 305m reel reduces splice requirements and per-foot cost on multi-zone commercial audio installations.
• RoHS Compliant — Meets EU RoHS-2 restricted substance requirements for projects with environmental compliance documentation needs.

Frequently Asked Questions

What is the difference between 14 AWG and 16 AWG speaker cable for commercial AV installations?

14 AWG has a larger conductor cross-section, which lowers DC resistance per foot. This matters for longer speaker runs in commercial AV systems where resistance loss in the cable can reduce amplifier damping factor and reduce power delivery to the speaker. As a general guideline, 16 AWG is appropriate for runs up to approximately 50–80ft at 8 ohms, while 14 AWG extends practical run length to 100–150ft or more at the same impedance before insertion loss becomes significant. Consult your amplifier's damping factor specifications and speaker impedance for precise run length calculations.

Is this cable suitable for 70V distributed audio systems?

Yes. 14 AWG 2-conductor cable is commonly specified for 70V (and 100V) constant-voltage distributed audio systems in commercial AV installations. At 70V, the high distribution voltage reduces current draw per watt, allowing longer cable runs with less loss than low-impedance 4–8 ohm systems. 14 AWG is appropriate for 70V systems with heavier total wattage loads or longer backbone runs between the amplifier and transformer tap points.

Can this cable be installed in plenum air-handling spaces?

No. The 14-2C-BLK is rated NEC CL3R (riser) and CEC CMG, which qualifies it for in-wall vertical riser runs between floors but not for air-handling plenum spaces. For installations in plenum ceiling spaces or air-handling ducts, specify a CL3P or CMP-rated plenum speaker cable such as the Liberty AV 14-2C-TTP-WHT.

What termination method is recommended for this cable?

The stranded conductors terminate cleanly into spring-clip or binding post speaker terminals, as well as spade lug or banana plug connectors with proper crimp tools. For 70V transformer tap connections and commercial amplifier barrier strip outputs, use appropriately rated wire ferrules or fork terminals to prevent conductor strand spreading. Strip only the minimum jacket length needed to avoid exceeding the amplifier or speaker terminal's recommended uninsulated conductor exposure.

Is this cable rated for class 2 or class 3 low-voltage power applications?

Yes. The NEC CL3R rating covers both Class 2 and Class 3 remote-control, signaling, and low-voltage power circuits as defined under NEC Article 725. This makes the cable suitable not only for speaker-level audio but also for DC power distribution to AV control interfaces, IR emitters, relay control, and similar low-voltage AV system control wiring within NEC Article 725 current and voltage limits.

How many feet per reel and what is the recommended storage and handling?

Each reel contains 1000ft (305m) of cable. Store reels in a dry location between -40°F and 140°F (-40°C to 60°C). Do not install PVC-jacketed cable in ambient temperatures below the jacket's rated minimum installation temperature; cold PVC can crack during pulling. Unreel from the inside of the reel or use a motorized payoff stand for smooth high-speed pulls in commercial installation environments.

What is the NEC article governing this cable type?

Speaker cable rated CL3R falls under NEC Article 640 (Audio Signal Processing, Amplification, and Reproduction Equipment) and Article 725 (Class 1, Class 2, and Class 3 Remote-Control, Signaling, and Power-Limited Circuits). For speaker-level wiring from amplifiers to loudspeakers, the CL3R rating satisfies NEC requirements for Class 3 circuits in riser spaces. Always verify local building code adoption of the applicable NEC edition with your AHJ.
