2 Core Round Speaker Cable - Single-Jacket OFC In-Wall Speaker Cable

The 2 core round speaker cable is a two-conductor audio cable with both cores enclosed inside a single round outer jacket. Unlike flat twin-lead speaker wire, the round profile is designed to be pulled through conduit, wall cavities and ceiling voids for permanent in-wall installation. Jiaxing Doublewin Cable Co., Ltd manufactures this cable in-house in Haiyan, Zhejiang, China, using oxygen-free copper (OFC) stranded conductors and PVC or LSZH jackets, with CL2/CL3 (NEC) and CPR EN 50575 compliance. We supply it in bulk to distributors, integrators and OEM/ODM partners worldwide.

✓Conductor: Multi-stranded bare OFC copper

✓Insulation: Colour-coded (red / black) for clear polarity

✓Cabling: Two cores laid together with uniform lay length

✓Outer Sheath: Single round PVC or LSZH flame-retardant jacket

How to Select The Proper AWG Size for Your Speaker Cable

Cable length and amplifier output determine your ideal wire gauge. Larger conductors (smaller AWG value) deliver power efficiently across long distances, cutting down resistance and audio signal attenuation. Share your project specifications, and our team will advise the most suitable cable build for your installation.

Durable 2-core round speaker cable for public address, stage, studio and commercial audio projects.

Typical Applications

The 2 core round speaker cable is the installer's choice for permanent audio wiring where the cable is hidden inside walls, conduits or ceilings:

In-Wall Home Theater

Hidden speaker runs inside wall cavities for surround sound and distributed home audio, rated CL2/CL3 for NEC compliance.

Commercial PA & BGM

Offices, retail, hotels, restaurants and warehouses where speaker cable is routed through ceilings and conduit.

Conduit & Trunking Runs

Long pulls through electrical conduit and cable trunking - the round profile prevents binding at elbows.

Public Buildings & Schools

LSZH jacket option for hospitals, schools and public transport where low smoke and zero halogen are required.

OEM / ODM Round Speaker Cable Customisation

As an OEM round speaker cable manufacturer, we build cable to your exact specification - from conductor gauge and jacket material to colour, outer print legend and retail packaging. This is ideal for audio brands, distributors and project integrators needing private-label or project-specific bulk round speaker cable.

Customisable Options

Conductor gauge (12/14/16/18 AWG) and stranding count
Conductor material: OFC, CCA or tinned copper
Jacket material: PVC or LSZH (low smoke zero halogen)
Jacket colour and sequential metre marking
Brand print legend on the outer jacket
Reel size, box label and packaging (305 m / 1000 ft standard)

Quality Control & Testing

Every 2 core round speaker cable reel is electrically tested before it leaves our factory. We retain a sample of each production batch so any future claim can be traced back to its copper raw material lot. Test reports are supplied with every order, and third-party inspection (SGS, BV, TÜV or your nominated agent) is welcome at any production stage.

Lead Time, Packing and Shipping

Stock items Standard specifications kept in warehouse for short-notice orders.
Custom orders 20–25 working days after sample approval. Sampling 5–7 working days.

Why Choose Our 2 Core Round Speaker Cable

The round speaker cable form factor is the preferred choice for professional installers because a single round jacket pulls more smoothly through conduit and tight wall cavities than flat twin-lead wire. The two colour-coded conductors are individually insulated and protected by one durable outer sheath, giving a neat, professional finish.

Round Single-Jacket Design

Two conductors inside one round sheath - pulls through conduit and wall cavities without twisting or binding.

CL2 / CL3 In-Wall Rated

Compliant with NEC Article 725 for in-wall residential and commercial installation (CM/CL2/CL3 ratings available).

Oxygen-Free Copper (OFC)

99.95% pure OFC stranded conductors deliver low resistance and clear, consistent audio signal transmission.

Flexible Stranding

Multi-stranded conductors remain easy to strip and terminate, even after long conduit pulls.

FAQ

Q: What is a 2 core round speaker cable?

A: 2 core round speaker cable contains two insulated conductors (usually red and black) enclosed inside a single round outer jacket. The round profile is designed to be pulled through conduit, wall cavities and ceiling voids for permanent in-wall installation, unlike flat twin-lead speaker wire which is intended for surface runs.

Q: What is the difference between round speaker cable and flat speaker wire?

A: Round speaker cable has both conductors inside one round sheath, which makes it easier to pull through conduit and suitable for in-wall installation (CL2/CL3 or CPR rated). Flat twin-lead wire has two conductors bonded side-by-side and is generally used for short, visible surface runs where flexibility matters more than fire rating.

Q: Is 2 core round speaker cable suitable for in-wall use?

A: Yes. Our 2 core round speaker cable is available with CL2/CL3 ratings (NEC) for the North American market and CPR EN 50575 compliance for the EU, making it suitable for in-wall and in-conduit installation in residential and commercial buildings. We can produce LSZH jacket versions for public buildings requiring low smoke and zero halogen.

Q: Are you a round speaker cable manufacturer or a trading company?

A: We are a manufacturer. Jiaxing Doublewin Cable Co., Ltd owns and operates its factory in Haiyan, Zhejiang, where we draw conductors, extrude insulation, cable the pairs, apply the sheath and test finished cables in-house. You are welcome to visit our plant or request a live video tour.

Q: Can you print our brand on the round speaker cable jacket?

A: Yes. Jacket print, jacket colour, length marking and packaging can all be customised. Please send us the exact print legend you require and we will confirm it on a sample before mass production. Custom print MOQ is 10,000 m.

Q: What certifications do your round speaker cables hold?

A: Our factory holds ISO 9001:2015 certification, and our cables are CE and CPR EN 50575 compliant. CL2/CL3 documentation is available for in-wall installations. All cables supplied into the EU market are RoHS compliant. Certificate copies and test reports are available on request.
