Unverified85% confidenceFactTime unknown
灵敏度每差3dB，达到相同响度所需功率翻倍。85dB以下的低灵敏度音箱（如经典小型监听箱）需要大功率功放伺候，86-90dB是较易驱动的舒适区间

Unverified驱动低灵敏度音箱（<85dB）需要更大功率储备：灵敏度每降3dB，达到同等音量需功率翻倍，如83dB音箱在20平米房间建议功放≥100W/声道93% similarUnverified喇叭灵敏度(dB)每提高3dB相当于功率翻倍，客厅/大空间选灵敏度≥88dB的喇叭，用小功率功放即可获得足够音量；灵敏度低于85dB需搭配大功率功放85% similarUnverified灵敏度≥88dB的音箱易被小功率功放推响，灵敏度<85dB的音箱（多为低阻高解析款）需更大功率储备，小房间近场监听可接受较低灵敏度换取解析力80% similarUnverified无源音箱（需搭配功放）灵敏度＜86dB时，功放输出功率建议≥100W/8Ω，否则大动态时推力不足声音发闷78% similarUnverified只用IEM入耳耳塞（阻抗＜32Ω，灵敏度≥110dB）选择输出功率200mW以内的中端播放器即可，盲目追求推力反而会放大底噪并缩短续航77% similar
