Speaker cable electro base PBA150-LZ 2x1.50 mm² oxygen-free copper, professional audio

Professional speaker cable electro base PBA150-LZ 2x1.50 mm² oxygen-free copper is designed for reliable transmission of audio signals between amplifiers and loudspeakers. The cable features two conductors each with a cross-sectional area of 1.50 mm² made from oxygen-free copper to ensure low resistance and minimal signal loss. Flexible insulation and a durable outer sheath facilitate routing in PA systems, studio installations and permanent home audio runs while maintaining long service life and stable contact performance.

Advantages

The balanced construction with two oxygen-free copper conductors provides improved conductivity and reduced oxidation compared with standard copper, resulting in clearer mid and low-frequency response for connected speakers. Flexible insulation allows tight bends and easier installation in confined spaces without compromising conductor integrity. The robust outer jacket offers mechanical protection against abrasion and light impact, supporting repeated handling during live events and system reconfigurations.

Suitable for

• Permanent and temporary PA system wiring
• Studio monitor connections
• Home audio and multi-room speaker runs
• Live sound reinforcement and stage setups

Key specifications

• Conductor configuration: 2 conductors
• Conductor material: oxygen-free copper
• Conductor cross-section: 1.50 mm² per conductor
• Electrical characteristic: low DC resistance suitable for speaker-level signals
• Insulation: flexible polymer insulation for each conductor
• Outer sheath: durable protective jacket for mechanical resistance
• Application temperature range: suitable for indoor installations and typical live-use environments

How to use

Strip the outer sheath and individual conductor insulation to the required length for your connector type, taking care not to nick the copper strands. Twist or ferrule the conductor strands as recommended by the amplifier and speaker terminal practices to ensure secure clamping. Route the cable along walls, channels or cable trays and avoid sharp bends with radii smaller than recommended for flexible speaker cable. For long runs, verify polarity at both ends and test continuity and resistance before permanent fixation.

Usage recommendations

Use appropriate strain relief at terminals and avoid run exposure to excessive heat or moisture. For runs longer than typical home distances, consider using heavier gauge conductors to reduce voltage drop; for installations with repeated reconnection, use quality connectors and periodically inspect terminations for oxidation or loosening.
