Two conductors make one loudspeaker circuit \u2014 one positive and one negative \u2014 so this model is the single-feed unit of the LBSRVS jacketed range at the 4.0 mm\u00b2 section, and the building block that the 4-core, 6-core and 8-core 4.0 mm\u00b2 models repeat.<\/p>\n<h2>Where the LBSRVS-2X4.0 Fits in a Project<\/h2>\n<ul>\n<li><strong>Single loudspeaker feeds where the section is fixed by the specification:<\/strong> projects that standardise on 4.0 mm\u00b2 (12 AWG) for every loudspeaker line use this model for the one-speaker runs and a multi-core model for the grouped runs, all in the same jacket family.<\/li>\n<li><strong>Sound reinforcement:<\/strong> amplifier-to-loudspeaker runs in sound reinforcement and fixed audio wiring where a heavier conductor is specified than 1.5 \/ 2.5 mm\u00b2.<\/li>\n<li><strong>Subwoofer and low-impedance feeds:<\/strong> one circuit per cable, terminated as a pair; the 11 mm jacket sits between the 2 \u00d7 2.5 mm\u00b2 (9.8 mm) and the 4 \u00d7 4.0 mm\u00b2 (12.5 mm) models in the same range.<\/li>\n<\/ul>\n<h2>The 4.0 mm\u00b2 Section Across the LBSRVS Jacketed Range<\/h2>\n<p>4.0 mm\u00b2 is the largest section outside the 6.0 mm\u00b2 models and is published in four core counts.

Send the run length, amplifier output per channel and loudspeaker impedance, and the section is confirmed against that rule.<\/p>\n<h3>Can this model feed several loudspeakers?<\/h3>\n<p>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 \u2014 the multi-core models in this range exist to run several separate circuits in one pull, not to increase the load on one circuit.<\/p>\n<h3>Does LBS publish the same section in a reinforced construction?<\/h3>\n<p>Yes \u2014 the LBSRVH range publishes a reinforced main speaker cable at 4.0 mm\u00b2 for touring and rental use; the LBSRVS models on this page are the jacketed standard construction.<\/p>\n<h3>Can jacket printing, colour, cut length and packaging be agreed for a project?<\/h3>\n<p>Construction, jacket colour, printing, length, packaging and branding can be reviewed according to the confirmed product and project quantity for OEM \/ ODM projects.
