Speaker Wiring, commonly referred to as series or parallel wiring, is a crucial aspect of loudspeaker systems. It involves connecting multiple speakers to an amplifier to achieve different sound characteristics and impedance levels.
Series Wiring connects speakers in a linear fashion, with the output of one speaker connected to the input of the next. This configuration increases the total impedance of the system, typically doubling or tripling it with each additional speaker. Series wiring is often used to reduce the load on an amplifier or to create a high-impedance system for certain applications.
Parallel Wiring, in contrast, connects speakers side-by-side, with the positive terminals of all speakers connected together and the negative terminals connected together. This configuration lowers the total impedance of the system, effectively dividing it by the number of speakers. Parallel wiring is commonly used to increase the overall volume and power handling of a system.
The choice between series or parallel wiring depends on factors such as the desired impedance, sound quality, and amplifier capabilities. In home audio systems, parallel wiring is more common as it allows for lower impedance and higher power handling. In professional sound reinforcement systems, series wiring may be used to achieve higher impedance and reduce the load on amplifiers.
A key historical development in series or parallel speaker wiring was the introduction of impedance matching transformers. These transformers allow speakers with different impedance ratings to be connected in series or parallel without causing impedance mismatches, which can damage amplifiers or speakers.

The impedance of a speaker is determined by its voice coil design and magnet strength. Common speaker impedance ratings include 4 ohms, 8 ohms, and 16 ohms. It is important to match the impedance of the speakers to the impedance rating of the amplifier to achieve the desired sound quality and power output. -
Series Wiring and Impedance
When speakers are wired in series, the impedance of each speaker is added together to calculate the total impedance of the system. For example, two 8-ohm speakers wired in series would have a total impedance of 16 ohms. -
Parallel Wiring and Impedance
When speakers are wired in parallel, the impedance of each speaker is effectively divided by the number of speakers. For example, two 8-ohm speakers wired in parallel would have a total impedance of 4 ohms. -
Impedance Matching
It is important to match the impedance of the speakers to the impedance rating of the amplifier. If the impedance of the speakers is too low, it can overload the amplifier and cause damage.
