2-Core Speaker Audio Cable – OFC Pure Copper Wire

 

Let's break down what each part of this name actually means:

Term	Meaning
2-Core	The cable contains two insulated conductors (one positive, one negative) inside a single outer jacket-the standard configuration for connecting one amplifier channel to one speaker
Professional	Built to meet the demands of live sound, touring, and installed audio systems-not consumer-grade
HI-FI	High-Fidelity design ensures accurate signal transmission with minimal coloration or distortion
Stage	Designed for outdoor and stage use-rugged jacket, weather-resistant, and built to withstand frequent handling and harsh environments
Audio Cable	Specifically engineered for speaker-level audio signals, not power distribution or instrumentation
OFC Pure Copper Wire	Uses Oxygen-Free Copper conductors-high-purity copper with reduced oxygen content for superior conductivity and corrosion resistance

 

In simple terms: This is a rugged, two-conductor speaker cable made from pure OFC copper, designed for professional stage, live sound, and HI-FI audio installations where durability and sound quality matter.

 

 

 

 

 

This series is available in multiple conductor cross-sections to match different power handling and installation requirements. The table below shows the International Standard (mm²) alongside the AWG equivalents for easy reference:

 

 

Model	Conductor Size (mm²)	AWG Equivalent	Application Recommendation
2×0.75mm²	0.75 mm²	~18 AWG	Short runs (≤10m), low-power bookshelf speakers, surrounds
2×1.0mm²	1.0 mm²	~17 AWG	Medium runs, moderate power systems
2×1.5mm²	1.5 mm²	~16 AWG	Standard home theater, most bookshelf/monitor speakers
2×2.0mm²	2.0 mm²	~14 AWG	Floor-standing speakers, medium-length runs (≤20m)
2×2.5mm²	2.5 mm²	~13 AWG	High-power systems, longer runs (≤30m)
2×4.0mm²	4.0 mm²	~11 AWG	Professional PA systems, very long runs, subwoofers
Custom	Custom sizes	Custom	Tailored to specific project requirements

 

Key Point for International Audiences: This cable uses the metric system (mm²) for conductor sizing-the standard in most countries outside North America. The AWG equivalents are provided for reference, but always verify with the mm² spec for accuracy.

 

 

 

 

Here's what's inside the cable, layer by layer:

 

 

Visual breakdown:

 

Component	What It Is
Conductor	High-purity OFC (Oxygen-Free Copper) stranded wire-the "core" that carries the audio signal
Insulation	Premium PVC color-coded insulation (Red for positive / Black for negative)
Filler/Binder	Optional inner wrapping to keep cores centered and maintain round cable shape
Outer Jacket	Thick, durable PVC outer sheath-the "armor" that protects against the elements and physical abuse

 

Material Breakdown (What Each Part Is Made Of)

 

1. Conductor Material: Oxygen-Free Copper (OFC)

High-purity OFC strands ensure low signal loss, clear audio transmission, and long-lasting performance for professional audio systems.

 

Property	Specification
Material	Oxygen-Free Copper (OFC)
Purity	≥ 99.99%
Oxygen Content	≤ 0.001%
Conductor Type	Multi-strand stranded construction (multiple fine wires twisted together)
Strand Count	Varies by gauge (more strands = more flexibility)

 

Why OFC matters:

- Lower resistance compared to CCA (Copper-Clad Aluminum) or standard copper

- Less signal degradation over long cable runs

- Superior oxidation resistance-connections stay clean over time

- Better solderability for connector termination

 

2. Insulation Material: Premium PVC

Premium PVC material provides excellent electrical insulation, wear resistance, and protection against moisture and external damage.

 

Property	Specification
Material	Premium PVC (Polyvinyl Chloride)
Color Coding	Conductor 1: Red / Conductor 2: Black (or other color pairs available)
Thickness	Optimized for electrical safety and mechanical protection
Dielectric Strength	Excellent insulation properties prevent shorts and signal leakage

 

Why PVC insulation:

- High dielectric strength prevents electrical shorts

- Resists abrasion, oils, and chemicals commonly encountered in stage environments

- Maintains flexibility across a wide temperature range

- Flame-retardant properties enhance safety

 

3. Outer Jacket Material: Durable PVC

Property	Specification
Material	Industrial-grade PVC
Color	Black (standard; custom colors available)
Characteristics	Abrasion-resistant, weather-resistant, flexible

 

Why the outer jacket is critical for stage use:

- Protects internal conductors from physical damage during setup/teardown

- Resists moisture, UV exposure, and temperature extremes for outdoor use

- Provides extra "grip" for cable coiling and handling

 

 

Feature	Description
Pure OFC Conductors	99.99% Oxygen-Free Copper for superior signal transmission and corrosion resistance
Multi-Strand Design	Multiple fine copper strands per conductor deliver excellent flexibility-easily coils, routes, and bends without memory effect
Color-Coded Cores	Red/Black insulation makes polarity identification quick and error-free during installation
Premium PVC Insulation	Provides reliable electrical isolation and mechanical protection
Durable Outer Jacket	Thick, rugged PVC sheath stands up to the rigors of touring, stage setups, and outdoor use
Multiple Gauge Options	0.75mm² ~ 4.0mm² (18 AWG ~ 11 AWG) to match any power requirement
Standard 100m/Roll	Convenient bulk packaging for project efficiency and cost savings
Outdoor/Stage Ready	Engineered for demanding environments-weather-resistant and durable
Customization Available	Custom lengths, colors, packaging, and even OEM branding upon request

 

 

 

 

 

1. Superior Sound Quality

The high-purity OFC conductors minimize signal loss and maintain audio integrity from amplifier to speaker. Low resistance means your amplifier's damping factor stays intact-delivering tight bass, clear mids, and crisp highs.

 

2. Built for the Stage (and Beyond)

Unlike standard home audio cables, this cable is engineered for professional use:

 

Feature	Benefit for Stage/Outdoor Use
Thick PVC jacket	Resists cuts, kinks, and crushing during load-in/load-out
Weather-resistant	Handles outdoor festivals, humidity, and temperature changes
Flexible stranding	Coils easily for storage; lies flat during setup
Long 100m rolls	Ideal for large venues, touring productions, and fixed installations

 

3. Versatility Across Applications

One cable series covers everything:

- Small venues → 0.75mm² or 1.0mm²

- Medium venues and home HI-FI → 1.5mm² or 2.0mm²

- Large PA systems and subwoofers → 2.5mm² or 4.0mm²

 

 

4. Cost-Effective Professional Solution

OFC performance at a competitive price point-no compromise on materials, no unnecessary markup. The 100m roll format reduces per-meter costs for installers and contractors.

 

 

5. Long Service Life

OFC resists oxidation, PVC resists environmental degradation-this cable is built to last years of professional use.

 

 

 

 

 

Primary Applications

 

Application	Recommended Size	Notes
Professional Stage & Live Sound	2.5mm² ~ 4.0mm²	Main PA, monitor wedges, subwoofer runs
