The LBSRVS-8X4.0 is an 8-core, 4.0 mm² (12 AWG) jacketed speaker cable with OFC conductors, PVC conductor insulation and an overall PVC jacket (jacket O.D. 16.5 mm). Multi-core constructions like this let an installer run several loudspeaker circuits in one pull — for example eight individual feeds, or four pairs when each circuit needs two cores — which simplifies stage, studio and fixed-installation wiring compared with running separate two-core cables for every speaker.
Because all LBSRVS jacketed cables share the same OFC / PVC construction, a whole venue can be wired with one family: 2-core versions for single loudspeaker feeds, 4/6/8-core versions for grouped circuits, subwoofer feeds and zone wiring. Keeping the same jacket family also makes cable identification, termination and future maintenance easier.
For single-circuit runs, the 2-core versions of the same family are often a better fit: see the LBSRVS-2X4.0 and LBSRVS-2X2.5. When the project needs reinforcement-filled touring construction instead, the LBSRVH-8X4.0 is the reinforced alternative.
| Configuration | Typical use |
|---|---|
| 2 × 4.0 mm² (LBSRVS-2X4.0) | Single loudspeaker circuit, medium/long runs |
| 4 × 4.0 mm² (LBSRVS-4X4.0) | Two loudspeaker circuits or one stereo pair per pull |
| 8 × 4.0 mm² (LBSRVS-8X4.0) | Grouped circuits, zone wiring, subwoofer banks |
When a single conductor size must serve every circuit, the 8-core version gives the most flexibility in one cable: the installer can pair cores as needed on site. For the general principles of choosing conductor size by run length and power, see the speaker cable selection guide and the speaker cable gauge guide.
Yes. The 8 cores are individually insulated inside the overall PVC jacket, so an installer can fan out and terminate each pair or single core as the project requires. Polarity marking should be confirmed before termination.
Yes. The LBSRVS jacketed range includes 2, 4, 6 and 8 core versions from 1.5 mm² up to 6.0 mm², all with OFC conductors and PVC insulation/jacket.
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 8 conductors and a 16.5 mm jacket.
8 conductors carry 4 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.

In the same 8-core construction: The next size down is 3.0 mm² (13 AWG) with a 15.5 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.
