Description

The Mercury Economy is a 2-core speaker cable with copper-clad aluminium (CCA) conductors in a transparent PVC sheath, supplied on a 100m reel. Each core consists of 24 strands of 0.2mm diameter wire, giving a combined cross-sectional area (CSA) of 0.75mm² per core. A red polarity indicator runs along one core to simplify correct phase wiring during installation.

Designed for low-to-medium power PA systems, distributed audio in commercial spaces, and home hi-fi installations where moderate cable runs are needed, the transparent sheath allows the cable to blend into skirting boards, white walls and ceilings without drawing visual attention. The 6A maximum current capacity suits typical 8Ω passive speakers running at up to 50W RMS per channel in residential and light commercial settings.

The CCA conductor construction keeps the cable lightweight and reduces installation costs compared to pure copper equivalents, while the 3.1 x 6.2mm cross-section fits standard cable clips and twin-core termination blocks. The 100m reel length supports multiple room runs from a single spool, reducing waste and simplifying stock management for installers working across small-to-medium venue projects.

Frequently Asked

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

Copper-clad aluminium (CCA) has an aluminium core with a thin copper coating. It's lighter and lower-cost than pure copper, but has slightly higher resistance. For short-to-medium cable runs under 20m at typical home hi-fi or light PA power levels, the performance difference is negligible. For long runs or high-power professional PA, pure copper cable (OFC) provides better conductivity.

How do I identify polarity when wiring?

One core has a red polarity indicator printed or embedded along its length. This core is conventionally connected to the positive (+) terminal on both the amplifier and speaker to maintain correct phase. The other core connects to the negative (−) terminal.

What power can this cable handle?

The 6A maximum current rating supports approximately 50W RMS per channel into an 8Ω speaker load. This suits typical bookshelf speakers, ceiling speakers in distributed audio systems, and small PA satellite speakers in commercial settings.

Can it be used outdoors?

No. The transparent PVC sheath is not UV-stabilised or weather-resistant. For outdoor speaker runs, use cable rated for external or buried installation.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund. See full delivery terms.

Returns

30-day returns window from delivery. As all our products are electrical or lighting goods, returned items must be inspected and recertified by a qualified electrician before resale — the cost of this inspection (25–40% of the item value) is deducted from your refund. Customers pay return shipping. Made-to-order, special-order and clearance items cannot be returned. See full returns policy.
