我跟你學嘢咋!

你昨晚問較sub仔phase

My old post:

簡單2句, "相位" 係 0-360度 "Waves / phase of sound "聲音的度數...
與 "degree of subwoofer positson " subwoofer 面向角度度數並無直接關係...0-360度係好多ching的迷思
只知大多數都係 "0" <<< 我估係理由係好多人唔識就set"0"lor...否則
如有0 & 180度選...0只係1/2機會
如有0, 90, 180, 270度選...0只係1/4機會
如有0 -360度無段選...0只係1/360機會...就算面向那,都係1/360, 所以正確的0度冇理多過一半...小弟現玩面向皇帝位同backfire 都用正確相位180...

θ is sometimes referred to as a phase-shift, because it represents a "shift" from zero phase. But a change in θ is also referred to as a phase-shift.

For infinitely long sinusoids, a change in θ is the same as a shift in time, such as a time-delay. Ifis delayed (time-shifted) byof its cycle, it becomes:


但Phase 只關 Front, subwoofer, king seat 三樣事, test 開CD 2.1 , 用5.1會亂...

CHing, 你明白什麼是Phase, 就知lee個世界暫時唔可能有人類用肉眼就會知什麼phase...
用2.1 較sub phase , 令3 spk 的低頻(below 100hx...80....50...30...etc up to u, u like la....)同步到皇帝位, 最大聲最實個點, 再反轉紅黑spk cable會出現out of phase 最弱, 那就是正確的sub 仔Phase{:6_195:}

等你再攪團 la !

而家你set器材好正, 小小意見不訪一試, 可能再有所提升:
1.認真做一次Aut Cal. 挪D Data做參考，特別係距離
2. Check一次sub仔正確phase, 唔一定係0 ka
3. 而家有少少高音偏多, 中音偏少
4. AV and 2ch 整體定位有少少偏高
....我唔識, 亂吹try try la{:6_195:}

Thx Joe 今天由北角座長途車來小弟家幫忙.............

他的器材及線材實太 pro 啦 !...

呢個陣容真係好利害！{:8_403:}
見識見識！{:8_389:}
