咁我重低音係要黎出低音,咁我係咪要教到最細?請問師兄們調幾大度數?

都係個句.唔識唔好調.在LEVEL調大細聲.

即係睇邊度?

部amp的設定上有Speaker config.入去有得調.

多數的十仔是背要靠牆.但MK可以正面靠牆.要睇你的家環境兒定.相位要睇你擺什麼地方?正面(12點方向) ...

ching, 我個十仔向地打, 但不是正面放, 是向左放, 咁應該點set呢? (個十仔只得0 & 180)?
謝

My old post FYR:

個phase...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. If is delayed (time-shifted) by of 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...

Phase 係0-360度...放邊到前/後都有齊0-360...唔會後有前冇..., 即以面向皇帝位, 一定會出現齊0-360度的機會, 只要距離改變, 例如加/減半個phase(180)的距離,其他數據, 前置不變, 面向皇帝位0度, 就一定會變面向皇帝位180度才正確,
故面向皇帝位是完整0度, 是有1/360的機會是對的

sub 的phase 與前置的phase 相同, 就會相加in-phase 即正確相位, 相反就相减即out-phase
基本上是沒有可能在沒有前置的資料下會預知正確的subw phase, 例如用反相spk又如何會正確?例如用不同的amp, spk距離又怎樣一樣subw phase...?

用2.1坐皇帝位test, 就是把 Front, subwoofer, king seat 三樣事的資料結合才得知phase issue

sub 的phase 與前置的phase 相同, 就會相加in-phase 即正確相位, 相反就相减即out-phase
即正確相位會sub & front spk 同時到達king seat 會無時間斷層(80-100hz),而聲音相加in-phase 當然最大聲

Indeed, the 0-180 phase setting has nothing to do with the position of your sub. It has to do with the phase shift and delays of your speakers, especially the sub. Get this right, and the integration between the sub and the speaker will be better.

The easy way to do this is to play some bass heavy music and then listen to your system at your king seat. The best setting should be the one where the bass sounds loudest or best integrated. Give it a try.
