The LBSRVH series covers main speaker cable from 2 × 1.5 mm² to 2 × 6.0 mm² plus 4-core and 6-core versions. The 2 × 4.0 mm² (12 AWG) construction is the mid-large cross-section in the series, specified for touring sound, professional audio installation and fixed building installation. It suits amplifier-to-speaker runs where the installer wants the current-carrying capacity of 4.0 mm² without stepping up to the heavier 2 × 6.0 mm² drum.
| Model | Conductor | Typical use |
|---|---|---|
| LBSRVH-2X2.5 | 2 × 2.5 mm² (approx. 13 AWG) | Short runs, monitors, lower-power amplifiers |
| LBSRVH-2X3.0 | 2 × 3.0 mm² | General PA and installation runs |
| LBSRVH-2X4.0 (this page) | 2 × 4.0 mm² / 12 AWG | Main speaker runs, touring sound, fixed install |
| LBSRVH-2X6.0 | 2 × 6.0 mm² | Long high-power runs, large PA systems |
As a rule of thumb for professional audio, longer runs and higher amplifier power call for a larger cross-section to limit resistance and voltage drop. For a main left/right speaker run over 20–30 m at typical PA power, 4.0 mm² is a common specification; above that, many engineers step up to 6.0 mm². For short monitor or fill runs, 2.5 mm² is usually enough.
This cable uses 4N oxygen-free copper (OFC) conductors with PVC insulation, cotton thread and cotton paper reinforcement, and a flexible PVC jacket at 11 mm outer diameter. The cotton filling keeps the pair geometry stable when the cable is coiled, packed and pulled on tour, and the flexible jacket helps the cable lie flat in cable trays and around racks. Jacket colour options (black, royal blue, dark green) make channel identification practical in multi-run installations.
Compare the twisted and parallel alternatives in the same factory range: the full speaker cable catalogue lists LBSRVH main cable, LBSRVS twisted speaker cable and LBSRVB parallel speaker cable, so the construction can be matched to the application — parallel for fixed racks, twisted for reduced induced noise in longer signal paths, and jacketed main cable for touring.
For stage and touring use, LBSRVH-2X4.0 is normally terminated with professional connectors such as the LBSSPK Speakon-compatible connector. In multichannel installations, the 4-core versions of the series (LBSRVH-4X4.0, LBSRVH-6X4.0) let an installer run two or three speaker circuits in a single cable for bi-amping or distributed systems — see the 4-core speaker cable for bi-amping guide for the wiring logic.
Please provide the required specification, length or packaging unit, quantity, application and destination country or region. LBS confirms the variant, drum or coil packaging and export packing against those details.
Jacket colour options are black, royal blue and dark green on the standard product. OEM / ODM projects — construction, jacket colour, printing, length, packaging and branding — can be reviewed according to the confirmed product and project quantity through the LBS OEM process.
Yes — the page lists fixed building installation as a documented application alongside touring sound and professional audio installation. For long fixed runs, confirm the routing and required length with LBS before ordering.
4.0 mm² is the metric cross-section; 12 AWG is the equivalent American Wire Gauge designation. The LBS spec table lists the cable as 4.0 mm² / 12 AWG, so either naming convention can be used when specifying.
Yes — LBS supplies professional cable in custom lengths for projects. Send the per-run length and total quantity when requesting a quotation so the packaging and drum/coil arrangement can be confirmed.
