Speaker cable PSSO 30227933 4×2.5 mm, 20 m, black

The PSSO 30227933 speaker cable is a 20 m, black multi-core audio cable with four separate conductors of 2.5 mm² each. Designed for speaker and audio system connections, this cable supports dedicated runs for multiple channels or bi-wiring arrangements. The stranded conductors offer flexibility for routing in both domestic and professional installation environments, while the 2.5 mm² cross-section provides a balance of current capacity and low signal loss for typical loudspeaker loads.

Advantages

This speaker cable combines four insulated conductors in a single jacket, enabling neat multi-channel or bi-wire layouts without multiple separate cables. The 2.5 mm² conductor size is appropriate for medium-power speaker systems, offering reduced resistance compared with smaller gauge wires. Stranded construction improves flexibility for easier pulling and termination in wall cavities, conduits, or equipment racks. The outer black jacket provides a discreet appearance for visible runs.

How to use

Strip the outer jacket and insulation from the individual conductors to the required length, taking care not to nick the strands. Terminate conductors with appropriate speaker connectors (banana plugs, spade lugs, or screw terminals) or make secure screw-terminal connections at the amplifier and speaker ends. Observe polarity when connecting positive and negative channels to maintain correct phase. Route the cable avoiding sharp bends and sources of electromagnetic interference; secure runs with clips or cable ties where necessary.

Recommendations

For best performance, use this 4×2.5 mm cable for medium-power speaker circuits and bi-wiring applications. Keep run lengths as short as practical to minimise signal loss, and ensure solid mechanical terminations to prevent increased resistance. When installing in-wall, check local building codes and use appropriate in-wall rated cable if required.
