Key performance indicators which speaker (4-5)? Tags: Professional HIFI stereo speaker factory - Key performance indicators Yi Ting stereo speakers are: sensitivity, frequency response, rated power, rated impedance, directivity, and distortion parameters. 4, the distortion of the original sound speaker can not realistically reproduced the phenomenon called distortion. There are two kinds of distortion: frequency distortion and nonlinear distortion. Frequency distortion due to signal playback certain frequencies stronger, while for others the playback frequency of weak signal caused by damage to the proportion of the original low distortion sound degrees, changing the acoustic sound. And the nonlinear distortion is due to the fluctuation of the speaker vibration system of the vibration and the signal is not exactly the same result HIFI SPEAKER plant, adding a new frequency component in the acoustic output. 5, point feature is used to indicate the direction of the speakers in the space radiation of sound pressure distribution, the higher the frequency the more narrow directivity, the greater the stronger directional cone.
