1.What is the definition of two-way speaker and three-way speaker?
The two-way speaker is composed of a high-pass filter and a low-pass filter. And then three-way speaker filter is added. The filter presents an attenuation characteristic with a fixed slope near the frequency division point. The intersection of the decay phases of adjacent curves is usually called the frequency division point. There is an overlapping band near the divider, and in this band both speakers have outputs. Theoretically, the larger the attenuation rate of the filter, the better. However, the larger the attenuation rate, the more components, complex structure, difficult adjustment, and the greater the insertion loss.

Two-way speaker dividing point is between 2k to 4KHz, If the treble power is large, the dividing point should be lower, and the directivity frequency response will be better. For example, the treble power is small, the dividing point can only be higher. By splitting the treble, mid-range and bass frequencies, the sound control is more pronounced.
2. The difference between three-way speaker and two-way speaker:
1) Different composition: two-way speaker box generally has more than two units, treble unit and bass unit; A three-way speaker box is generally divided into three or more units, including treble unit, alto unit and bass unit.
2) The structure is different: the box of the two-way speaker box has two horn holes; The case of a three-way speaker has more than three horn holes.
3) Different characteristics: the sound field effect and sound quality of the two-way speaker are good; The three-way speaker box makes the music more hierarchical because it divides the frequencies according to the frequency characteristics of different units.
