Speaker Cable

Speaker cable is a two-core, polarity-marked cable that carries the amplified audio signal from an amplifier or AV receiver to passive loudspeakers. We stock 79 strand 2 core speaker cable on a 100mt coil, a practical size for home cinema, multi-room audio, background music and small PA installations.

The fine-stranded conductors make it easy to route and terminate. Order on a trade account for trade pricing; if it is in stock and you order by 5pm on a weekday, it arrives the next working day in NI or ROI.

Choosing and installing speaker cable

Speaker cable is simple in construction but makes a real difference to how a system sounds and how easy it is to install. With a single 79 strand 2 core cable in stock, the main decisions are about run lengths, routing and termination.

Why conductor size matters

Speaker cable carries relatively high current at low voltage, so resistance in long runs reduces power reaching the speaker and can affect bass response. Keep runs as short and equal in length as practical, especially for left and right pairs. For very long runs or low-impedance speakers, check the amplifier and speaker manufacturer's recommendations on conductor size.

Typical applications

Home cinema surround systems, including rear speakers routed through ceilings or walls
Multi-room audio with in-ceiling or in-wall speakers
Background music in shops, cafés and offices
Small PA and paging systems (check whether a 100V line system needs a different cable)

Installation tips

Maintain polarity: one conductor is marked, so connect it to the positive terminal at both the amplifier and the speaker. Reversed polarity on one speaker causes thin, phasey sound. Avoid running speaker cable tightly alongside mains cables for long distances, and use separate containment where possible. For concealed runs, plan first-fix routes before plastering and leave enough slack at each speaker position.

On surface runs, small cable clips or mini trunking keep the cable neat and protected. For other low-voltage cables, including coax and network cable, see our communication cable range.

Terminating the cable

Strip only enough insulation to fit the terminal, twist the fine strands together so no loose strands can short across terminals, and tighten binding posts firmly. Banana plugs or ferrules make repeated connections easier.

FAQ's Ask Your Own Question

Does it matter which way round speaker cable is connected?: Yes. One conductor is marked so you can keep polarity consistent, connecting it to the positive terminal at both the amplifier and the speaker. If one speaker is wired the wrong way round, the speakers work against each other and the sound becomes thin, with weak bass.
Can speaker cable be run inside walls?: Speaker cable is often concealed in walls and ceilings for home cinema and multi-room systems. Plan routes at first fix, protect the cable from nails and screws, and keep it away from mains cables where possible. Check any local building or fire requirements for cables in voids and escape routes.
How long can a speaker cable run be?: There is no fixed limit, but resistance increases with length, which reduces power and can affect sound quality. For typical room and home cinema runs, standard 2 core speaker cable is fine. For very long runs, check the amplifier and speaker manufacturer's guidance on conductor size.
Is speaker cable suitable for 100V line PA systems?: Two-core cable can be used on many 100V line systems, but these systems operate at higher voltages than standard low-impedance speakers. Check the PA system designer's specification and any fire safety requirements, as some installations, such as voice alarm systems, require fire resistant cable.
Should I use banana plugs on speaker cable?: Banana plugs are optional but make connecting and disconnecting speakers easier and help prevent stray strands shorting across terminals. If you connect bare wire, twist the strands tightly and insert only the stripped section into the binding post or spring terminal.
How is your speaker cable supplied?: Our 79 strand 2 core speaker cable comes on a 100mt coil, enough for most home cinema and multi-room jobs. In-stock orders placed by 5pm Monday to Friday are delivered the next working day across Northern Ireland and the Republic of Ireland.
