Speaker cable LIBOX 2x2.50 mm² model LB0009-20, 20 m length

LIBOX 2x2.50 mm² speaker cable, model LB0009-20, is a two-conductor audio cable supplied in a 20 m length intended for connecting passive loudspeakers to amplifiers in home and small professional audio systems. The cable features a 2.50 mm² conductor cross-section per core, providing a balance between current-carrying capacity and manageable flexibility for typical room-to-room speaker runs. Construction and length make it suitable for short to medium wiring distances where maintaining signal integrity and minimizing voltage drop are important.

Advantages

The cable offers a consistent conductor size across both cores, which helps ensure stable impedance and reduced resistance along the run. Its 20 m length covers most living-room and small-studio layouts without requiring splices, and the 2.50 mm² cross-section is commonly used for moderate-power speakers. The design supports straightforward termination with banana plugs, spades, or stripped-wire connections and is compatible with a wide range of amplifier and speaker binding posts.

Suitable for

• Wiring bookshelf or floor-standing speakers in a home audio setup
• Connecting speakers to small power amplifiers in rehearsal rooms or small venues
• Replacing or extending existing speaker runs where moderate conductor size is required
• Temporary or semi-permanent installations in domestic and light commercial environments

Key specifications

• Number of conductors: 2 (two-core)
• Conductor cross-section: 2.50 mm² per core
• Length: 20 meters
• Application: speaker to amplifier audio connections
• Suitable termination: stripped wire, banana plugs, spade connectors

How to use

Measure the required run and route the cable avoiding sharp bends and sources of electromagnetic interference. Strip an appropriate length of insulation from each conductor, taking care not to nick the copper strands, and attach suitable connectors or insert directly into binding posts according to the amplifier and speaker terminals. Observe correct polarity by matching the positive and negative conductors at both ends to maintain proper speaker phase. Secure the cable along the route with clips or cable ties to prevent movement and mechanical strain.

Usage recommendations

For best audio performance, keep cable runs as short as practical and avoid running speaker cable parallel to mains power cables to reduce potential interference. If the installation requires longer distances or higher power handling, consider a larger conductor cross-section. When terminating the cable, ensure clean, tight connections and use the same polarity throughout the system.
