Unverified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86% 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82% 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82% 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82% similarUnverified室外开阔环境无墙壁反射声音扩散快，需20W以上功率才能形成足够声压；室内5-10W即可，室外买室内功率音箱会明显觉得音量不够78% similar
