set得好就一定better (好似好廢話咁)

但係個問題係，係咪真係set得好

CONCLUSIONS

• How many subwoofers are enough?

Four subwoofers are enough to get the best resullts of any configuration tried. Two subwoofers is
very nearly as good and has very good low frequency support as well.

理論上四隻已非常完美,因為四隻對稱咁擺法,基本上已可抵消橫向和直向既超低頻既room mode！
兩隻就只可抵消單一方向，另一個方向就要用皇帝位就下啦！
