The LBSRVS-4X4.0 carries four OFC conductors of 4.0 mm² (12 AWG) inside PVC insulation and an overall PVC jacket with a published outer diameter of 12.5 mm. Four individually insulated conductors make two loudspeaker circuits — one positive and one negative conductor per circuit — so this model feeds two loudspeakers, or one stereo pair, from a single pull.
| Model | Conductors | Loudspeaker circuits | Jacket O.D. |
|---|---|---|---|
| LBSRVS-2X4.0 | 2 | 1 | 11 mm |
| LBSRVS-4X4.0 (this page) | 4 | 2 | 12.5 mm |
| LBSRVS-6X4.0 | 6 | 3 | 15 mm |
| LBSRVS-8X4.0 | 8 | 4 | 16.5 mm |
Every row publishes the same 4.0 mm² (12 AWG) conductor, so the section question is answered once and only the number of circuits per pull changes. The 4-core model exists at 2.0, 2.5, 3.0, 4.0 and 6.0 mm²; this page is the 4.0 mm² member of that set.
Yes. The four cores are individually insulated inside the overall jacket, so they can be fanned out and terminated as two separate circuits at each end. Polarity marking should be confirmed before termination so the two circuits cannot be crossed.
Two 2-core cables and one 4-core cable carry the same two circuits; the 4-core version reduces the number of jackets and pulls, which matters in conduit. The section itself is decided separately, by run length and load.
Yes — the LBSRVH range publishes a reinforced main speaker cable in 4-core 4.0 mm² for touring and rental duty: see LBSRVH-4X4.0. The LBSRVS model on this page is the jacketed standard construction.
Construction, jacket colour, printing, length, packaging and branding can be reviewed according to the confirmed product and project quantity for OEM / ODM projects. Send the model, specification, quantity and destination to the LBS sales team.
Every size below is a published model in the same construction, read from each model's own specification sheet. This page is the 4.0 mm² size (12 AWG) with 4 conductors and a 12.5 mm jacket.
4 conductors carry 2 loudspeaker circuits: one positive and one negative conductor per circuit. A two-pole connector carries one circuit, a four-pole connector two — the pin-set rule is explained in NL2 vs NL4 vs NL8: Speaker Twist Lock Connectors.

Cross-section, not the model number, sets conductor resistance and therefore the loss over a given run: the length-versus-gauge table is in the speaker cable gauge guide, and the mm² / AWG conversion is set out in mm² to AWG.
Sizes published in this LBSRVS range: 21. Every model above is a separate specification sheet — send the model code, quantity and destination to request a cable specification.
