AV功放功率虚标普遍，看'全频段额定输出'（如20Hz-20kHz全驱动）而非单声道峰值；驱动大型落地箱需每声道100W以上RMS，书架箱60-80W足够

UnverifiedAVR功放选购看解码是否支持8K/4K120Hz直通（HDMI 2.1）和目标声道数，功率参数看'全声道同时驱动'实测值而非单声道峰值，标称100W×7的功放全驱动往往只有60-70W81% similarUnverified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78% similarUnverified有源中场功率看分频段总和：低频单元建议≥150W、高频≥50W（双功放/三功放Bi-amp），单声道总功率＜200W在大空间会在高声压时压缩失真78% similarUnverified功率越大低频储备越足但底噪也可能越明显，近场5寸箱单只50-80W已足够，盲目追求百瓦以上在小房间无意义78% 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77% similar
