Comparison Kisonli V-410 vs Kisonli V-400

A phase inverter is a tube of a special design that connects the inner volume of the speaker housing with the outer space. Due to the precisely selected length, such a tube improves the sound of low frequencies, making it more saturated and uniform. The main disadvantage of a phase inverter is that a hum may occur due to the movement of air in the tube; however, manufacturers design speakers in such a way as to minimize the likelihood of this phenomenon.

Note that the presence of a phase inverter is especially useful for subwoofers, but this feature can also be found in general-purpose stereo speakers — for the same reasons.

The sloping design of the front face of the speaker allows you to place the speakers in the case at an angle. Thus, the sound from them does not spread horizontally, but slightly upwards. This favorably affects the use of speakers near the monitor, when the distance from the listener to the audio system is insignificant. We can say that the inclined design allows you to direct the signal directly into the human ear. However, in fact it is more of an aesthetic nature. Therefore, computer speakers of a high price segment, and, accordingly, quality are rarely made inclined and more often have a straight body.
