低音喇叭

How quickly it transitions is pretty steep, so you might be able to get away with adding as little as 10Hz to your speaker's lowest reproduceable frequency. Start with 20, then tweak to preference to get the best transition.

When we talke about the strange life, this is art itself; We crossed the sharp condition from old memory to theMatrix; We play the international bass with our audio; We are calmly undertaken the politics into our mind even bone and blood; We open the cap, tear the plastic bag and turn the PLAY button; We hands up and open the window of world.

我们谈论诡异的生活，这就是艺术的本源；我们怀着昨日的老旧跨过新锐的火盆进入明天的黑客帝国；我们竖起高音喇叭播放International化的重低音；我们从容面对政治成为强加的妆容渗透入骨；我们打开瓶盖撕开塑封口袋摁下PLAY键；我们一个举手推开世界之窗一个投足五天揽月。
