Speaker cable ShiverPeaks 21108-CCA 2×0.75 mm² transparent CCA, twin conductor

Speaker cable ShiverPeaks 21108-CCA 2×0.75 mm² transparent CCA, twin conductor is a flexible twin-conductor audio cable with two 0.75 mm² copper-clad aluminium (CCA) cores and a clear outer sheath. It is intended for connecting loudspeakers to amplifiers in home and commercial audio installations. The transparent jacket exposes conductor polarity marking for easier identification and routing while offering a compact profile suitable for visible runs, in-wall installations where permitted, or short to medium cable lengths.

Advantages

The cable combines a lightweight CCA conductor with a pliable transparent jacket to provide a balance of flexibility and space-saving cross-section. Its twin-conductor design simplifies speaker wiring and polarity identification, and the 0.75 mm² conductor cross-section is adequate for many bookshelf and small-to-medium loudspeaker systems over short to moderate distances. The transparent sheath allows visual verification of conductor arrangement and reduces installation errors in multi-run setups.

Suitable for

• Connecting bookshelf and satellite speakers to home receivers and amplifiers
• Short to medium-length speaker runs in living rooms, studios, or commercial premises
• Visible cable routing where appearance and conductor identification are important
• In-wall installations where CCA conductors meet local electrical and building codes

Key specifications

• Conductor type: copper-clad aluminium (CCA)
• Number of conductors: twin (2 conductors)
• Conductor cross-section: 0.75 mm² per conductor
• Outer sheath: transparent flexible jacket
• Application: loudspeaker to amplifier audio connection
• Impedance/continuity: designed for low-frequency audio signal transmission

How to use

Strip the outer jacket and the conductor insulation to expose sufficient copper-clad aluminium for secure termination. Ensure correct polarity by following the conductor markings visible through the transparent sheath. Connect each conductor to the corresponding terminal on the speaker and amplifier, making secure screw or spring-clamp connections. For longer runs, consider using larger cross-section wire to reduce potential power loss. Avoid sharp bends and protect the cable from crushing or heavy mechanical stress.

Usage recommendations

Use this CCA-based speaker cable for short to moderate length runs where cost and flexibility are priorities. For high-power amplifiers, long cable runs, or critical audiophile systems, choose higher-purity copper conductors with larger cross-sections to minimize resistive losses.
