结果是相反的,SpeaD模拟可能不是很准.

42.6对应的是0.38

44.8对应的是0.48

好象不是上面这款.

知春DX，出题的DX的磁钢是双磁哦，是不是磁铁厚度应该改为28而不是14呢（如果是我理解的叠加的话....）

另外，出题的DX，24指的是音圈的卷幅还是（ .24）音圈的线径？这点有些模糊...

这款更不像:

Type-X subwoofers give you extremely high sound quality and overall performance. They use a number of the
same parts and technologies as the superb AlpineF#1Status models, but are offered at a much more affordable price.
What’s more, their networks provide incredible tuning capabilities, so the units can be used anywhere in the vehicle and always deliver maximum performance.

结果还是差不多:

0.36

0.46

非常谢谢知春!我还说等我回家了上传上来,没有想到你真是个有心人啊!!

请将那个T铁的穿孔改为15mm 谢谢!!

另外DAAS 提出的问题我回答在这里.是双磁.在磁铁的厚度那里请输入28.音圈的卷幅为24mm

还有一个事情就是如果用390V充磁,Qts就会到0.17.如果哪位XD有时间,我带你们去实地看看就知道了!包括那些说我"蒙"他的人,还有那个"中山门".

型号是SWL-1042. 其中的SWL-1242在去年的CAR-HIFI评比中获得第一名.

如果大家抱着互相交流的目的,而不是排斥一些真正有讨论意义的东西.我还可以把这个12寸设计中的一些经典章节分享给大家.

如果大家能够找出真正的原因,本人在方便的时候带他(她)一起去德国,哈哈,反正是那边的人出银子!
