在音箱的设计制作中,无论是专业人员还是业余爱好者,人们都将音箱的声压曲线尽量地向低频端平滑延伸,使之不陡然下降,以期获得较高的低频声压。目前的各种音箱,在已确定扬声器的情况下,不管其体积大小,形式如何,实际上都在为得到完美的低频而努力。 其实,解决低频声压问题的方法早已有之,即3D系统。在3D系统中,用两只体积较小的音箱(亦称卫星音箱)良好地再现中低音、中音和高音,而利用低音方向性 In the speaker design, whether professionals or hobbyists, people are the sound pressure curve of the speaker as far as possible smooth extension of the low-frequency side, so that it does not fall sharply, in order to obtain a higher low-frequency sound pressure. The current variety of speakers, in the case of the speaker has been identified, regardless of their size, form, in fact, are in order to get the perfect low-frequency work. In fact, the solution to the problem of low-frequency sound pressure has long been there, that 3D system. In a 3D system, the bass, mids and treble are well reproduced with two smaller speakers (aka satellite speakers), while the bass directivity
