Cabo de coluna ShiverPeaks 06-21075, 2,5 mm² (50×0,25) CCA, vermelho/preto, 10 m

ShiverPeaks 06-21075 is a 10 m speaker cable with a 2.5 mm² conductor cross-section made from 50 strands of 0.25 mm copper‑coated aluminum (CCA). The cable is supplied with a twin red/black outer jacket to mark positive and negative polarity, simplifying connection between amplifiers and speakers. Its construction balances electrical conductivity and weight to suit installations in homes, small commercial venues and basic audio systems where a cost‑effective wiring solution is required.

Advantages

The cable provides a clear polarity indication through the red and black conductors and features a 2.5 mm² cross‑section that supports typical speaker-level signals. CCA construction offers reduced weight and lower cost compared with solid copper while maintaining sufficient mechanical flexibility for routing behind furniture and through conduit. The 10 m length covers most room layouts without additional splices, and the stranded design helps prevent breakage when stripping and terminating.

Suitable for

• Connecting home stereo or multiroom speakers to AV receivers and amplifiers
• Short to medium run installations in cafes, small meeting rooms or retail audio systems
• Temporary setups, demo areas or events where budget cabling is acceptable
• Runs where polarity marking is required for consistent speaker phasing

Key specifications

• Length: 10 m
• Conductor cross‑section: 2.5 mm²
• Stranding: 50 × 0.25 mm strands per conductor
• Conductor material: copper‑coated aluminum (CCA)
• Outer jacket: twin red/black for polarity identification
• Application: speaker‑level audio connections

How to use

Measure the required run between amplifier and speaker, allow extra length for routing, and cut the cable to size. Strip an appropriate amount of insulation from each conductor, taking care not to nick the strands. Connect the red and black conductors to the corresponding positive and negative speaker terminals on the amplifier and speaker, ensuring secure screw or clamp terminations. If using banana plugs, ferrules or spade connectors, crimp or solder according to the connector manufacturer’s instructions before inserting into the terminals.

Recommendations

For best results, keep runs as short as practical and avoid parallel routing with mains power cables to minimize interference. Use correct polarity throughout the system to preserve speaker phase and sound imaging. Inspect terminations periodically for corrosion or looseness, especially in humid or public environments.
