Speaker cable electro base PBA250-LZ 2x2.50 mm² oxygen-free copper, red+black

Speaker cable electro base PBA250-LZ 2x2.50 mm² oxygen-free copper, red+black is a two-conductor audio cable designed for reliable speaker and audio equipment connections. Each conductor has a 2.50 mm² cross-sectional area and is made from oxygen-free copper to reduce oxidation and maintain low electrical resistance. The cable is supplied with red and black polarity insulation to simplify correct speaker wiring and ensure consistent signal polarity in installations.

Advantages

The oxygen-free copper conductors provide improved conductivity and reduced risk of signal loss over short to moderate runs. A 2x2.50 mm² conductor size offers a balance between flexibility and current-carrying capacity suitable for most home and many professional audio setups. Clear red and black polarity marking simplifies installation and helps prevent phase inversion when connecting multiple speakers or amplifier channels.

Suitable for

• Wiring bookshelf or floor-standing speakers in home audio systems
• Connecting speakers in small to medium professional sound installations
• Replacing existing speaker cables in hi‑fi systems
• Fixed in-wall or surface-mounted speaker runs where a durable conductor is needed

Key specifications

• Conductor configuration: 2 conductors (stereo/bi-wire compatible)
• Conductor cross-section: 2 x 2.50 mm²
• Conductor material: oxygen-free copper
• Insulation colors: red and black for polarity identification
• Typical use: low-resistance speaker cable for audio signal transmission

How to use

Strip a suitable length of insulation from each conductor without damaging the copper strands, then attach to speaker terminals or binding posts following the red/black polarity convention: red to positive (+) and black to negative (−). For secure connections, use banana plugs, spade lugs, or properly tightened screw terminals. Route the cable to avoid sharp bends, kinks, or placement near strong electromagnetic interference sources. For in-wall or concealed runs ensure compliance with local building codes and use appropriate conduit or rated cable types if required.

Usage recommendations

For best audio performance, use this 2x2.50 mm² cable for distances up to moderate lengths where low resistance is important; consider larger conductor sizes for long runs or very high-power systems. Maintain correct polarity across all speaker connections to preserve phase and imaging.
