Impedance

The electrical resistance of the speakers to alternating current. This parameter is important primarily for normal compatibility with the amplifier: too low speaker impedance can lead to distortion, overload, and even damage to the speakers, and too high impedance can reduce the sound volume. At the same time, the vast majority of modern computer acoustics have their own amplifiers and are connected via a line input. Therefore, the impedance data is more of a reference value; in fact, this indicator may be needed only when connecting speakers to a “non-native” power amplifier, bypassing the standard one.
