Procab loudspeaker cable ALS25/1 — 2 x 2.5 mm² (13 AWG) CCA, 100 m

Procab ALS25/1 is a 100-meter loudspeaker cable featuring two parallel conductors of 2.5 mm² (13 AWG) made from CCA (copper-clad aluminum). Intended for fixed speaker installations and audio distribution, this cable balances conductivity, weight and cost to meet the requirements of low- to medium-power sound systems. The 100 m reel format simplifies long runs for residential, commercial or installation projects where extended lengths are needed.

Advantages

The cable uses copper-clad aluminum conductors to reduce weight and material cost while retaining acceptable conductivity for many speaker setups. With a 2.5 mm² conductor cross-section, it supports reliable signal transmission over longer distances compared with thinner loudspeaker cables. The reel length of 100 m enables continuous runs without splices, reducing connection points and installation time. The construction is suitable for fixed installations and professional audio distribution where budget and cable weight are considerations.

Suitable for

• Long-run loudspeaker wiring in homes and small venues
• Commercial background music and paging systems
• Fixed installations in restaurants, retail spaces and offices
• Audio distribution where lower cable weight is required

Key specifications

• Conductor type: copper-clad aluminum (CCA)
• Number of conductors: 2 (parallel)
• Conductor cross-section: 2.5 mm² (13 AWG)
• Length: 100 meters
• Suitable application: loudspeaker / audio distribution
• Format: reel for continuous runs

How to use

Cut the required length from the 100 m reel and strip the insulation from each conductor to expose the copper-clad core. Maintain correct polarity throughout the run to preserve speaker phase alignment. Route the cable away from strong electromagnetic interference sources such as power lines or fluorescent fixtures where possible. For permanent installations, secure the cable at regular intervals and terminate with appropriate connectors or terminals rated for the conductor size. Avoid excessive bending radii and protect the cable where it passes through walls or conduits.

Usage recommendations

For best results in low- to medium-power systems, match cable runs and amplifier output, and keep individual run lengths within practical limits to maintain adequate signal level. When higher power handling, lower resistance, or maximum fidelity is required, consider using pure copper conductors instead of CCA.
