Speaker cable Procab CLS225-CCA/3, dual conductor 2 x 2.5 mm², CCA

Procab CLS225-CCA/3 is a dual-conductor speaker cable engineered for audio installations where flexibility and cost-effective conductivity are needed. The cable uses copper-clad aluminium (CCA) conductors with a cross-sectional area of 2 x 2.5 mm², making it suitable for short to medium runs between amplifiers and loudspeakers in home, studio or commercial environments. The jacket and conductor construction balance mechanical flexibility with electrical performance to support clear signal transfer in typical audio setups.

Advantages

The CCA construction provides a lighter-weight and more affordable alternative to pure copper while maintaining adequate conductivity for many installation scenarios. The 2 x 2.5 mm² cross-section offers a practical compromise between current-carrying capacity and ease of routing, and the dual-conductor format simplifies polarity identification and connection. The cable’s flexibility and insulation are designed to withstand common handling during installation and to fit into conduits, trunking or wall cavities where space is limited.

Suitable for

• Connecting passive loudspeakers to amplifiers in home audio systems
• Fixed audio installations in studios, conference rooms and small commercial venues
• Short to medium in-wall or surface-mounted speaker runs where cost and weight are considerations

Key specifications

• Conductor type: copper-clad aluminium (CCA)
• Configuration: dual conductor
• Conductor cross-sectional area: 2 x 2.5 mm²
• Designed use: speaker/ loudspeaker connections
• Typical installation length: short to medium runs (room-scale and small venue distances)
• Flexibility: suitable for routing through conduits and wall cavities

How to use

Strip an appropriate length of the outer jacket and insulation from each conductor, taking care not to nick the metal. Maintain correct polarity by matching the marked or coloured conductor to the positive terminal on the amplifier and speaker. Use suitable connectors or properly soldered/bare-finished terminations, tightened securely to speaker and amplifier terminals. Keep cable runs as short as practical to minimise resistance and signal loss; avoid tight coils or sharp bends that can stress the conductor or insulation.

Usage recommendations

For optimal performance, use Procab CLS225-CCA/3 in short to medium runs and avoid long-distance speaker feeds where pure copper conductors are preferred. Ensure secure, low-resistance terminations and protect the cable from moisture, mechanical damage and excessive heat during and after installation.
