Why Choose Our LSZH 2 Core Speaker 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 LSZH 2 core speaker cable?

A: LSZH 2 core speaker cable is a two-conductor audio cable designed to transmit audio signals between amplifiers and loudspeakers. It adopts low smoke zero halogen outer sheath, and is widely used for public address and background music systems in public and commercial buildings.

Q: What does LSZH mean in speaker cable?

A: LSZH stands for Low Smoke Zero Halogen. When burned, this cable jacket releases very little smoke and no toxic halogen acid gas. It protects people and equipment in case of fire.

Q: What is the difference between LSZH and PVC speaker cable?

A: LSZH speaker cable emits low smoke and zero halogen toxic gas during fire, meeting strict public building safety requirements. PVC speaker cable has lower cost but will produce dense smoke and corrosive halogen gas when burning.

Q: Is LSZH speaker cable fire-resistant?

A: LSZH refers to low smoke zero halogen material property, not fire resistance. Our LSZH speaker cable is flame retardant to slow flame spread. It does not maintain circuit continuity under long-time fire exposure unless specially engineered.

Q: Is LSZH 2 core speaker cable suitable for commercial buildings?

A: Yes. This LSZH 2 core speaker cable is ideal for commercial buildings, hotels, schools and other occupied public premises where low-smoke and non-toxic fire performance is required by codes.

Q: What conductor sizes are available?
