Mercury Figure 8 Speaker Cable 2 x 42 Strand 1.32mm² CCA - Black/White 100m Reel

The Mercury Economy Figure 8 is a 100m reel of 2-core speaker cable built with copper clad aluminium (CCA) conductors, each containing 42 strands of 0.2mm wire for a 1.32mm² cross-sectional area per core. The cable carries a 15A maximum current rating, making it suitable for mid to high-power distributed PA systems, commercial background music installations, and larger loudspeaker runs where cost-effective cabling is required without compromising signal integrity.

Designed for commercial installers working across retail spaces, schools, conference halls and hospitality venues, the figure 8 profile keeps the two cores bonded in a single flat sheath for faster routing and neater cable management. The black outer sheath carries a white polarity marking on one core, allowing installers to maintain consistent phase alignment across multiple speaker runs without having to mark or tag the cable. The 3.8 x 7.6mm cross-section is slim enough to run under carpet edging or through conduit while remaining thick enough to resist crushing during installation.

The 100m reel length suits professional installers who need to complete multiple speaker positions from a single cable supply without joins. The CCA conductor material balances cost against performance — it provides reliable signal transfer for most PA and background music applications at a lower price point than pure copper equivalents, though pure copper cable is recommended where the highest conductivity is required over very long runs or where high-end audio fidelity is the priority.

What's the difference between CCA and pure copper speaker cable?

Copper clad aluminium (CCA) consists of an aluminium core with a copper coating. It provides reliable signal transfer for most PA and background music applications at a lower cost than pure copper. Pure copper cable offers higher conductivity and is preferred for long runs over 50m or where audiophile-grade fidelity is required, but for typical commercial PA installations the CCA construction performs well.

What speaker impedance and power does this cable support?

The 15A rating and 1.32mm² CSA make this cable suitable for 100V line PA systems and passive speakers up to around 200W per run at typical 8-ohm impedance. For very high-power systems or runs exceeding 30-40m, consult the amplifier manufacturer's cable gauge recommendations to confirm the 1.32mm² CSA is adequate.

How is the polarity marking applied?

One of the two cores has a white stripe printed on the black sheath. This allows installers to maintain consistent phase alignment across multiple speaker positions without needing to mark or tag the cable during installation.

Can this cable be used outdoors?

The cable has no IP rating and the sheath is not UV-stabilised or weatherproof. It is intended for indoor use only. For outdoor speaker runs, use a cable specifically rated for outdoor or buried installation.
