Choosing OFC speaker wire starts with your equipment and the route between components. Check your speaker and amplifier manuals for wire recommendations, then measure the actual cable path, including turns around furniture and enough slack to reach the terminals comfortably. A lower American Wire Gauge (AWG) number indicates a thicker conductor; the appropriate gauge depends on factors such as run length, speaker impedance and terminal compatibility. Conductor count is a separate consideration. Two-conductor speaker wire provides the positive and negative paths for one conventional speaker connection. Four-conductor cable groups two pairs inside one outer jacket, which can be useful where an installation plan calls for two separate speaker circuits to follow the same route. Connection style and installation location can help narrow your oxygen-free copper speaker wire choices further. Bulk wire lets you cut individual runs to suit your layout, while pre-terminated speaker cables have connectors already attached. Check both ends of the connection: terminals that accept bare wire do not necessarily accept banana plugs, and connector compatibility should be confirmed in the equipment documentation. For concealed wiring, look for an explicit in-wall rating rather than assuming that any OFC cable is suitable. Outdoor and direct-burial installations also require cable rated for those particular conditions. Treat conductor material, jacket rating and connector type as separate specifications so your choice matches the whole installation, not just one feature.

FAQ

OFC stands for oxygen-free copper. It describes copper manufactured with very low oxygen content. The designation refers to the conductor material, not the cable's connectors, conductor count or installation rating.

No. Oxygen-free copper wire uses copper conductors, while copper-clad aluminum, often abbreviated CCA, uses an aluminum core covered with copper. Check the stated conductor material rather than relying on the wire's copper-colored appearance.

No, these cables serve different connections. Speaker wire typically carries amplified audio from an amplifier or receiver to passive speakers. RCA audio cables commonly connect analog line-level inputs and outputs, while optical cables carry digital audio. Match the cable to the labeled connections on your equipment.

These markings help distinguish the conductors so you can maintain consistent polarity. Follow any positive and negative labels provided by the manufacturer, and connect each conductor to the corresponding terminal at both ends. A stripe alone does not have a universal polarity meaning.

It depends on the design. Powered speakers contain amplification and typically receive audio through their specified analog, digital or wireless inputs. Some stereo pairs use speaker wire between a powered speaker and its passive companion. Check the speaker manual to identify the required connection.
