Description
The Mercury is a 100m reel of 2-core 0.75mm² speaker cable with a white double-insulated PVC sheath and hybrid copper/CCA conductors. Each core contains 12 strands of 0.2mm copper and 12 strands of 0.2mm copper-clad aluminium, giving a combined cross-sectional area of 0.75mm² per core and a 6A maximum current rating.
Designed for fixed installations in residential, commercial and education environments, the cable suits distributed audio systems, ceiling speaker runs, multi-room audio installations and public address installations where long cable runs are needed. The double insulation provides additional protection where cables run through wall cavities, ceiling voids or trunking, and the 7mm overall diameter keeps the cable flexible enough to route through conduit and around corners without kinking.
The white PVC sheath blends with white walls, ceiling tiles and skirting, reducing visual impact in exposed runs. The cable is supplied on two 50m reels, allowing separate runs to be pulled from a single box without needing to cut and rejoin mid-installation. The hybrid copper/CCA conductor design balances conductivity with weight and cost, making the cable suitable for voice and music reproduction where absolute audiophile conductor purity is not required.

Frequently Asked
What does CCA mean in the conductor specification?
CCA stands for copper-clad aluminium. This cable uses a hybrid design with 12 copper strands and 12 CCA strands per core. CCA strands have an aluminium core coated in copper, reducing weight and cost while maintaining acceptable conductivity for voice and music reproduction in distributed audio systems.
Is this cable suitable for outdoor use?
No. The white PVC sheath is designed for indoor installation. For outdoor speaker runs, use a cable with UV-resistant or buried-grade sheathing.
How is the cable packaged?
The 100m total length is supplied on two separate 50m reels in a single box. This allows you to pull two separate runs simultaneously or use one reel for a long run and keep the second reel for a different installation.
What impedance speakers can this cable drive?
The 0.75mm² CSA and 6A max current rating suit 4Ω, 8Ω and 100V line speakers. For runs longer than 15-20m to low-impedance speakers, consider stepping up to 1.5mm² cable to reduce voltage drop.
