hifidiy.net 团购的A501低音喇叭单体！
暂时先借用ccxxmm兄的图，

用Ａ５０１制作的ＯＮＥ仔！

我这次用她作了一个导向书架箱，经过几个月的调试后，因为很多认都买了这个喇叭，所以现将制作经验介绍一下．下面是我测的Ｔ／Ｓ参数，使用的是SpeakerWorkshop软件．详细参见http://www.speakerworkshop.com/SW/Download.htm

但是后来人们普遍用H702仿制.

应该没什么问题吧?

H702的Q值只有0.2，与A501的0.49相差甚远，两者的箱体不应该相同或相近。体积过小的话会导致混响严重的

发烧者米七

我都不敢下2K，有个2K的方案指标很好的，但是，，高音不够好啊！

维卡亚

昨晚测了手上的另一个高音。结果得BS一下国产的质量。两个不对称。在频响上是另一个的下限不行。阻抗也有区别但总体曲线还是差不多。

现在等钳版的A501等得……………………

没准这个真是出口版。

，听起来也不错解析力也可以。就是我买的时候还不懂。给JS摆了一刀。说是出口型。卖我一百多一个。唉。传上偶模拟的频响。因为还没有作箱我只是借用了梦版的501的频响图作的模拟。阻抗方面高频的阻抗比较高了。不知是我的高音灵敏度过高？也有可能是测量时用的音量不一吧。总之看个大概。分频点比较低。才1。56K这样的分频法灵敏度就很低了。提些建议。以后还要改。其实有想作双501的想法。作成哑铃式的。

昏哈...4-12的不防磁版本4-11,我手上也有一对,一直拿当小白鼠试制作的功放呢...从来没测量过这单元的曲线,居然有这样的水平,不错呀...我买得便宜,60一对,哈哈...[em11]

我现在手上没米了...也在想实在不行就买个YINDI的高音用着先...请问你的YINDI高音是什么型号的?[em05]

两条曲线都是通过单独测量，然后通过计算软件算出合成频响的，而没有直接测量最终的频响。我试验的实际差距还是有的，尤其加上分频器以后。。。。

另外请教一下，有没有考虑话筒的频响

昏...justMLS的那个应该是箱子上了分频器的实际测量曲线!~前面一张是LSPCAD通过单独测量的高低音单元曲线合成的结果,这样比较怎么不合适了?我也自己测量对比过LSPCAD的模拟结果和实际测量结果,可以说曲线是很吻合的....
如果你的整体测量结果和之前的单元分别测量后用LSPCAD模拟的结果不一致,问题肯定出在你那儿,两次用的是不是一样的测量环境?你的测量环境如何?呵呵...
还有MIC的问题,测量用的MIC,我们业余的一般都用PANASONIC的WM61A,60AT,60AY之类的...这些是宽频MIC,频宽能从20HZ---20000HZ,虽然说不是绝对平直,但是大家玩测量的一般都有针对自己MIC的校正文件,这样的情况下,只要环境没问题,测量结果是非常可靠的!~

以下是模拟频响和实测频响(灰线和黑线分别是左右声道,).除了高底端受测量环境和指向性影响,中高频是吻合的!可见用该软件模拟是可以信赖的!
