Cabo de coluna PSSO RE-30, 2x2,5 mm², 3 m, preto

PSSO RE-30 speaker cable, 2x2.5 mm², 3 m, black is a twin-conductor flexible cable designed for connecting loudspeakers to amplifiers, receivers or powered speakers. The cable provides two separate conductors with a 2.5 mm² cross-sectional area each, delivering low resistance for clear audio signal transfer in home audio systems and small installations. The black jacket offers a discreet appearance for visible runs and easy integration into existing setups.

Advantages

The cable combines a 2x2.5 mm² conductor configuration with flexible insulation to balance mechanical pliability and electrical performance. Its larger conductor area compared to thinner speaker wires reduces voltage drop and heating on longer or higher-power runs, supporting stable loudspeaker operation. The separate positive and negative conductors make polarity identification straightforward during installation, and the durable outer sheath protects the conductors from abrasion and everyday wear.

Key specifications

How to use

Strip the insulation from each conductor end without damaging the strands, observe correct polarity when connecting to amplifier and speaker terminals, and secure connections using appropriate terminal types such as banana plugs, spade connectors or bare wire clamping. Route the cable to avoid sharp bends and sources of interference, and leave slight slack to prevent tension at connection points. For best contact, twist stranded conductor ends or use ferrules where applicable to maintain strand integrity when clamped.

Recommendations

For typical home audio use, the 2.5 mm² conductor area is suitable for short to medium-length runs and moderate amplifier power. Avoid running speaker cable in parallel with mains power cables for extended distances to reduce potential interference. If using higher-power amplifiers or very long runs, consider verifying impedance and power handling to determine whether a larger cross-section is required.
