12 Facts About Speaker wire
2.
The shorter and thicker a Speaker wire is, the lower is its resistance, as the electrical resistance of a Speaker wire is proportional to its length and inversely proportional to its cross-sectional area .

3.
The Speaker wire's resistance has the greatest effect on its performance.
| FactSnippet No. 977,536 |
4.
The capacitance and inductance of the wire have less effect because they are insignificant relative to the capacitance and inductance of the loudspeaker.
| FactSnippet No. 977,537 |
5.
Low-resistance speaker wire allows more of the amplifier's power to energize the loudspeaker's voice coil.
| FactSnippet No. 977,538 |
6.
The performance of a conductor such as speaker wire is therefore optimised by limiting its length and maximising its cross-sectional area.
| FactSnippet No. 977,539 |
7.
Speaker wire's impedance takes into account the wire's resistance, the wire's path, and the dielectric properties of local insulators.

8.
Commonly available C11000 Electrolytic-Tough-Pitch copper wire is identical to higher-cost C10200 Oxygen-Free copper wire in speaker cable applications.

9.
Voltage on a speaker wire depends on amplifier power; for a 100-watt-per-channel amplifier, the voltage will be about 30 volts RMS.

10.
Voltage on a speaker wire depends on amplifier power; for a 100-watt-per-channel amplifier, the voltage will be about 30 volts RMS.

11.
Speaker wire cables are normally made with stranded conductors but bare metal strands in contact with each other do not mitigate skin effect; the bundle of strands acts as one conductor at audio frequencies.
| FactSnippet No. 977,544 |
12.
Speaker wire terminations facilitate the connection of speaker wire to both amplifiers and loudspeakers.
