Van Damme Black Series 4 Core 4mm Speaker Multicore Cable — 268544000
The Van Damme Black Series 268544000 is a high-power tour-grade speaker multicore cable carrying four 4.0mm² ultra-pure oxygen-free copper conductors in a single flexible jacket — the 4.0mm² step-up in Van Damme’s Black Series multicore range, built for professional sound reinforcement systems where conductor size is the primary specification driver. Where the 2.5mm² 268542000 covers the majority of general touring and installation applications, the 268544000 is the correct cable when high-power amplification, long cable runs, or the demands of professional line array and point source systems require the lower resistance and higher current capacity that 4.0mm² conductors deliver.
The distinction between 2.5mm² and 4.0mm² in a speaker multicore cable is not about audio quality — both use the same ultra-pure oxygen-free copper conductors and share the same Van Damme Black Series construction philosophy. The distinction is purely electrical: the 268544000 carries more current with less resistance per metre, which matters in specific system configurations where the 2.5mm² conductor size would introduce unacceptable power loss or compromise the amplifier’s damping control over the speaker load.
When 4.0mm² Is the Right Specification
The move from 2.5mm² to 4.0mm² is driven by three factors, alone or in combination: power level, run length, and damping requirements.
At higher amplifier power levels — professional line array amplifiers driving 2 ohm loads per channel, or high-power point source amplifiers running at full rated output — the current draw increases significantly compared to mid-power systems. The 268544000 at 4.60 Ω/km conductor resistance (versus 7.65 Ω/km for 2.5mm²) reduces voltage drop in the cable path and ensures more of the amplifier’s output power reaches the speaker cone rather than being dissipated as heat in the cable. On a 30-metre bi-amp drop to a high-power line array cluster, the difference in power delivery between 2.5mm² and 4.0mm² conductors is operationally meaningful at professional power levels.
Run length compounds the resistance effect. For amplifier-to-speaker runs beyond 20–25 metres in high-power systems, or in installation environments where the amplifier room is remote from the speaker positions, the 268544000’s lower resistance per kilometre maintains performance over distances where 2.5mm² cable would be marginal. System designers specifying distributed sound reinforcement in large venues — stadiums, arenas, large conference facilities — typically specify 4.0mm² conductor size as a minimum for any run beyond 20 metres at professional amplifier power levels.
Damping factor is the third consideration. An amplifier’s ability to control speaker cone movement depends partly on the ratio of amplifier output impedance to the total series resistance in the cable path. Lower cable resistance means higher effective damping factor at the speaker terminals — tighter bass, better transient control, and less frequency response variation with cone movement. In systems where sonic performance is a priority alongside raw power handling, the 268544000’s lower resistance delivers a measurable improvement in damping preservation over the 2.5mm² alternative.
127-Strand 4.0mm² Conductors for Flexibility Without Compromise
The 268544000 uses 127 × 0.20mm stranding per conductor — 127 individual copper filaments at 0.20mm diameter — producing a 4.0mm² conductor that remains genuinely flexible despite the large cross-section. Fine stranding at this count distributes bending stress across a large number of thin filaments, preventing the stiffness and conductor fatigue that heavier stranding would introduce in a cable regularly deployed and coiled on tour. The overall diameter of 12.20mm keeps the cable manageable in cable trays, looms, and conduit for a 4-core cable at this conductor size.
PVC insulation on each core and a special flexible PVC composite outer jacket in matte black complete the construction. Working voltage is rated to 300/500V — appropriate for the output swing of professional power amplifiers at high power levels.
