Cabo de coluna PSSO 3022791J, 2×4 mm², 20 m, preto

Speaker cable PSSO 3022791J, 2×4 mm², 20 m, black is a twin-conductor audio cable designed for connecting loudspeakers and audio equipment in home and professional installations. With two 4 mm² conductors and a 20-meter length, the cable provides a low-resistance path for audio signals, enabling consistent performance over moderate distances. Its black outer sheath suits visible runs and in-wall routing where a discreet appearance and reliable electrical contact are required.

Advantages

The cable’s 4 mm² conductor cross-section reduces voltage drop and minimizes signal loss, supporting clearer sound and better power transfer to passive speakers. The twin-conductor design keeps polarity identification straightforward during installation. A durable outer jacket protects the conductors from mechanical damage and ensures stable performance during fixed installations and in-wall routing.

Key specifications

How to use

Measure and cut the required length from the 20 m roll, leaving extra length for termination and routing. Strip the outer sheath and insulation from each conductor to expose the copper for secure terminations. Maintain correct polarity when connecting to amplifiers and speakers: mark or follow the cable’s conductor identification to avoid phase inversion. Use appropriate connectors or solder joints and ensure secure mechanical fastening to speaker terminals and amplifier outputs. Route the cable away from power lines and sources of electromagnetic interference to preserve signal quality.

Recommendations

For best performance, keep cable runs as short as practical and avoid tight bends that could stress the conductors. When installing in-wall, verify local building codes and use fire-rated conduit or cable if required. If longer runs or higher power levels are needed, consider a larger conductor cross-section or active amplification to maintain audio quality.
