Round Loudspeaker Cable - OFC 2-Conductor PA & Professional Audio Cable

Round loudspeaker cable is a two-conductor oxygen-free copper (OFC) audio cable built in a single round profile jacket, designed for professional PA systems, 100V/70V distributed audio and fixed commercial installations. The round cross-section pulls cleanly through conduit and cable trays, and the colour-coded red & black conductors keep polarity correct across long distributed runs. Jiaxing Doublewin Cable Co., Ltd manufactures this cable in-house in Haiyan, Zhejiang, China, in sizes from 10 AWG to 18 AWG, and supplies it in bulk to audio distributors, integrators and OEM/ODM partners worldwide.

Why Choose Our Round Loudspeaker Cable

For professional audio and distributed PA systems, the round profile loudspeaker cable is the installer-preferred choice. Unlike flat twin-lead, the round jacket slides through conduit, trunking and cable trays without snagging, and the symmetrical cross-section gives a cleaner appearance in exposed runs. Our cable is built with pure OFC conductors for low resistance over long distributed runs.

FAQ

Q:What is round loudspeaker cable?

A:Round loudspeaker cable is a two-conductor audio cable built in a single round profile jacket, designed for professional PA systems, 100V/70V distributed audio and fixed commercial installations. The round cross-section pulls cleanly through conduit and cable trays, and the colour-coded red & black conductors keep polarity correct across long distributed runs.

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

A:Round loudspeaker cable has a single symmetrical jacket over two cores, which slides through conduit and cable trays without snagging - ideal for fixed installs. Flat loudspeaker cable has two parallel conductors in a ribbon, which lies flat against a surface but catches at conduit bends. Round is preferred for permanent commercial and PA work; flat is more common for portable or under-carpet use.

Q: Can I use round loudspeaker cable for 100V / 70V distributed audio?

A:Yes. Round loudspeaker cable is commonly used for 100V and 70V distributed PA systems. The round profile is ideal for the long cable runs typical of distributed audio. Select the AWG based on total line power and cable length - 14 AWG or 12 AWG for long trunk runs, 16 AWG or 18 AWG for short ceiling speaker drops.

Q: What AWG size do I need for my PA system?

A:The correct AWG depends on cable length and total speaker load. As a guide: 18 AWG for short drops up to 10 m, 16 AWG up to 20 m, 14 AWG up to 30 m, 12 AWG for runs over 30 m, and 10 AWG for very long or high-power stadium runs. For 100V/70V distributed audio, contact our engineers for a calculation based on your line length and total transformer load.

Q: Are you a round loudspeaker 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 loudspeaker cable jacket?

A:Yes. Jacket print, jacket colour, length marking and packaging can all be customised. We can print your brand, AWG gauge and sequential metre marking. 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.
