再玩Room Analyzer Part 2 In-Phase還是Out of Phase好?

昨晚試過用下面條curve去睇戲真係無令到低頻失蹤唔見晒，即全無效果

Sub-woofer + Front (Sub-woofer volume: 10 o'clock Polarity: positive Phase: 0 degree elf: -8dB Front crossover: 80hz Sub-woofer crossover: 80hz)

之後要將sub-woofer的volume校返到12點位，才有返正常的低頻效果

Sub-woofer + Front (Sub-woofer volume: 12 o'clock Polarity: positive Phase: 0 degree elf: -8dB Front crossover: 80hz Sub-woofer crossover: 80hz)

Full Range

RTA

睇到就算將sub-woofer volume加大都只係會令到16hz至5Xhz音量增加，6Xhz打後並没提升。但如果phase不改變但將Polarity由positive換成negative的話，60hz會boost得好厲害。

Sub-woofer + Front (Sub-woofer volume: 10 o'clock Polarity: negative Phase: 0 degree elf: -8dB Front crossover: 80hz Sub-woofer crossover: 80hz)

基於以上情況，相信如果將polarity set做positive是out of phase，但假設唔能夠以EQ去削平63hz一段，各位會選用out of phase而得到較平嘅curve還是會用要一個在63hz有高peak嘅in phase setting?
