Unverified若房间小于10平米且无声学处理，不建议买8寸以上大单元监听，近距离低频驻波和过量声压会导致监听不准，5寸单元反而更真实69% similarUnverified警惕标称'放大50倍/100倍'的宣传，声音放大以分贝(dB)衡量而非倍数，模糊的倍数宣传通常是低质产品的营销话术，应索取具体增益(dB)和频响范围参数69% similarUnverified面积过小的房间（＜10㎡）不建议单纯堆叠低频陷阱：此类房间低频驻波往往集中在特定频点，盲目增加吸声体只会让房间变'死'（高频过吸），应先用测量软件找出问题频率再针对性布置67% similarUnverified覆盖面积与速率是矛盾的：三频放大器牺牲一个频段做专用回程保速率但覆盖略窄且贵，双频放大器覆盖广但中继衰减速率，小户型看剧优先三频，大平层保覆盖可选双频65% similarUnverified音质越强的音箱体积和重量越大，也越不便于多房间移动布置；追求全屋覆盖不如买多个可组网的小音箱（立体声配对/多房间同步）而非单个大音箱65% similar
