高保真音箱约定俗成的最低标准是频响提升不超过3dB,故其频响或有效频率范围的限制条件为±3dB,其中-3dB为频响高低端上下限的条件,即频响低端-3dB处的频率与频响高端-3dB处的频率,+3dB为对频响平直程度的要求,即频响曲线凸起不超过+3dB。监听音箱主要用于录音控制室内作为返听箱为录音师提供录音棚(或录音现场)的实
Hi-Fi speaker convention generally the lowest standard is to enhance the frequency response does not exceed 3dB, so the frequency response or effective frequency range limit of ± 3dB, of which -3dB for the high and low end of the frequency response conditions, namely the low-frequency response - The frequency at 3dB and the frequency at the high end of the frequency response at -3 dB, + 3dB are the requirements on the degree of flatness of the frequency response, that is, the frequency response curve does not exceed + 3dB. Monitor speakers are mainly used for recording control room as the back box for the recording studio to provide recording studio (or recording site)
