二、有源超低音音箱 大家知道,要使音箱发出深沉而强劲的低音,就需要利用大振膜扬声器在箱体里进行大幅度的低频振动,使音箱能够排出和吸人大量空气,而要做到这一点,就需要使用大口径扬声器、大容积箱体和大功率低频放大器。本刊上期介绍的小型立体声有源音箱虽然音质不错,但所用低音扬声器的口径只有13cm,箱体容积仅约4升,其100Hz以下的低频响应并不理想,需要用一只单独的超低音音箱来弥补本扬声器系统的低频响应。下面介绍的小型超低音有源音箱就是为此而专门设计的。
Second, the active subwoofer As we all know, to make the speaker issued a deep and strong bass, you need to use large diaphragm loudspeaker in the cabinet for a substantial low-frequency vibration, the speaker can exhaust and inhale a lot of air, and to To do this, you need to use large-caliber speakers, large-capacity boxes and high-power low-frequency amplifier. The small stereo speakers introduced in this issue, although the sound quality is good, but the bass speaker diameter of only 13cm, the cabinet volume of only about 4 liters, its low frequency response below 100Hz is not ideal, you need to use a separate subwoofer To compensate for the low frequency response of the speaker system. Here’s a small subwoofer active speaker is designed for this purpose.
