Description
The Mercury Figure 8 speaker cable is a 100m reel of twin-core audio cable with 13 strands of 0.2mm copper clad aluminium (CCA) conductor per core, giving a 0.41mm² cross-sectional area. The cable is rated for currents up to 2.5A and is designed for low-power speaker connections in domestic audio, small PA systems, and background music installations.
The white outer sheath includes a black polarity marking along one conductor, making it quick to identify positive and negative connections during installation. The slim figure 8 profile (2.0 x 4.0mm) routes easily through conduits, trunking, along skirting boards, or under carpets, keeping cable runs discreet in homes, offices, retail environments and hospitality venues. The 100m length allows multiple speaker runs from a single reel without joints.
CCA conductors provide a balance between cost and conductivity for applications where the speaker runs are short to medium length (typically under 10-15m per speaker) and the amplifier output is modest. The cable suits ceiling speakers, wall-mounted background speakers, and compact bookshelf speakers in rooms where the speaker distance from the amplifier does not exceed the cable's current and resistance limits. For higher-power or longer runs, consider upgrading to pure copper cable with a larger CSA.

Frequently Asked
What's the difference between CCA and pure copper cable?
Copper clad aluminium (CCA) uses an aluminium core with a thin copper coating. It's lighter and cheaper than pure copper but has higher resistance, so it's best suited to short to medium speaker runs (under 10-15m) with modest amplifier outputs. Pure copper cable offers lower resistance and is the better choice for longer runs or higher-power speakers.
What speaker applications is this cable suitable for?
The 0.41mm² CSA and 2.5A rating suit low-power ceiling speakers, wall-mounted background speakers, compact bookshelf speakers, and small PA applications where the amplifier output per channel is typically under 30-50W and the cable run is short. It's not recommended for high-power hi-fi or long outdoor runs.
How do I identify polarity on this cable?
One conductor has a black polarity marking printed on the white sheath. This conductor is typically connected to the negative terminal on both the amplifier and speaker to maintain consistent polarity across all speakers in a system.
Can this cable be used outdoors?
The cable is not rated for direct outdoor exposure or burial. For outdoor speaker installations, use cable with UV-resistant or direct-burial-rated sheathing.
