十仔setting需要考慮……

1. 空間與十仔單元(量感)是否配合

補充少少相位只係一個電阻，用嚟製造延遲，呢個可以用AV Receiver內面校距離代替的。

很多所謂“正確”理據的說法，在我經驗只是基礎理論
phase可令低頻上下左右移動，亦有人會覺得被神化
如懷疑可再來Q穴做實驗一次，只輕微一擰phase制
可將低頻(punch)調至打頭、心口、褲腳或心口與褲腳之間的，任君選擇！

咁好玩？咁就要玩下啦

我估你一定想調至心口與褲腳之間！

配合埋愛情動作片咪正爆

聲音傳送唔會分高音向上傳低音向下傳，因為聲音係無重量，呢個係誤解。
試下將隻subwoofer鑲死喺天花板就 ...

師兄對.因絕少人會將十仔鑲天花板.所以有此誤解.

師兄，太大力會變成男人最通喎

好呀，有機會再上你度學下嘢，
我相信上下左右移動係因為不同的訊號延遲而做成的不同反射及殘响，
你試下用AV Receiver去校下不同距離相信都會有呢個效果。

http://en.wikipedia.org/wiki/Subwoofer

Phase control[edit]
Changing the relative phase of the subwoofer with respect to the woofers in other speakers may or may not help to minimize unwanted destructive acoustic interference in the frequency region covered by both subwoofer and main speakers. It may not help at all frequencies, and may create further problems with frequency response, but is even so generally provided as an adjustment for subwoofer amplifiers.[23] Phase control circuits may be a simple polarity reversal switch or a more complex continuously variable circuits.

Continuously variable phase control circuits are common in subwoofer amplifiers, and may be found in crossovers and as do-it-yourself electronics projects.[24][25][26][27][28] Phase controls allow the listener to change the arrival time of the subwoofer sound waves relative to the same frequencies from the main speakers (i.e., at and around the crossover point to the subwoofer). A similar effect can be achieved with the delay control on many home theater receivers. The subwoofer phase control found on many subwoofer amplifiers is actually a polarity inversion switch.[29] It allows users to reverse the polarity of the subwoofer relative to the audio signal it is being given. This type of control allows the subwoofer to either be in phase with the source signal, or 180 degrees out of phase.

The subwoofer phase can still be changed by moving the subwoofer closer to or further from the listening position, however this may not be always practical.

做番d隔音比較好, 有同冇差好多

如果撞arm隣居係返shifts, 你又五怪得人.
玩得開心, 利己利人做返d隔音.

如開放q穴,可否下午進行? thx!
