This page introduces the classification of speakers based on the configuration of the units inside the speaker.
Inside the speaker (SP) there is a sound source section consisting of drivers, cones, etc., and on this page we will refer to it as a unit.
It would be great if just one unit could output all frequencies over a wide area, but that becomes difficult as the output power increases. Therefore, two or more units may be used to share the output frequency band. SPs can be classified according to the number of units.

1way (Single Unit)
It is an SP with only one unit.
Basically, when there are multiple units, interference will occur between the units, so a way to reduce this is required, but a single unit does not have this problem in the first place. This configuration has the potential to output the most ideal sound. Especially in the case of SP, where a relatively small sound is sufficient, developers may choose 1way in search of the ideal. When classified in this way, subwoofers are often classified as 1-way types.
For SPs that produce loud sounds, 2-way can output a wider frequency band to a wider area, but 1-way may be selected when reproduction of the audio band is important, such as in a PA system. Another aspect is that 1way is cheaper.

2way (Single amping)
There are two units within SP.
It is divided into units mainly responsible for high and low frequencies. By making it 2-way, this type of SP can output a wide range of frequencies with loud sound to a wide area. One signal is input from one AMP, and the high-frequency signal and low-frequency signal are separated by a circuit called a network. |
2way (Bi-amping)
This is a 2way SP that does not have a network circuit and connects an AMP to each unit.
It is necessary to separate the high and low frequencies of the signal using an external device such as a processor. The advantage is that this disassembly is not fixed by a network circuit, so engineers can do it freely. On the other hand, in order to output the optimal sound, work by a professional engineer is required. |
