The LBSRVS-2X4.0 carries two OFC conductors of 4.0 mm² (12 AWG) inside PVC insulation and an overall PVC jacket with a published outer diameter of 11 mm. Two conductors make one loudspeaker circuit — one positive and one negative — so this model is the single-feed unit of the LBSRVS jacketed range at the 4.0 mm² section, and the building block that the 4-core, 6-core and 8-core 4.0 mm² models repeat.
4.0 mm² is the largest section outside the 6.0 mm² models and is published in four core counts. Core count changes how many circuits travel in one pull; the conductor stays 4.0 mm² (12 AWG) in every row.
| Model | Conductors | Loudspeaker circuits | Jacket O.D. |
|---|---|---|---|
| LBSRVS-2X4.0 (this page) | 2 | 1 | 11 mm |
| LBSRVS-4X4.0 | 4 | 2 | 12.5 mm |
| LBSRVS-6X4.0 | 6 | 3 | 15 mm |
| LBSRVS-8X4.0 | 8 | 4 | 16.5 mm |
Below 4.0 mm² the same single-circuit construction is published as LBSRVS-2X2.5 (14 AWG) and LBSRVS-2X1.5 (16 AWG), and above it as LBSRVS-2X6.0 (10 AWG).
The run length and the load the amplifier drives decide it, not the model number: longer runs and lower-impedance loads push the requirement up the section ladder. Send the run length, amplifier output per channel and loudspeaker impedance, and the section is confirmed against that rule.
It carries one circuit (one positive and one negative conductor). Where several loudspeakers are wired in parallel on one line, the load on that circuit changes, which is a section question — the multi-core models in this range exist to run several separate circuits in one pull, not to increase the load on one circuit.
Yes — the LBSRVH range publishes a reinforced main speaker cable at 4.0 mm² for touring and rental use; the LBSRVS models on this page are 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 2 conductors and a 11 mm jacket.
2 conductors carry 1 loudspeaker circuit: 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.

In the same 2-core construction: The next size down is 3.0 mm² (13 AWG) with a 10.5 mm jacket. The next size up is 6.0 mm² (10 AWG) with a 12.5 mm jacket.
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.
