我测量的自做箱的频响
各位交流、指教!
时间窗可以用3MS
相位曲线也上来.这样还可看你测量距离填得如何.高音曲线可以了.[灌水]

只是远场!可能是我德 房间太小德缘故,反射难免。[讨论]

阻抗没问题
我用表直接测他的直流电阻也要11R左右。箱子只是两分频。低音较差。因为这只是远场测量。所以低频处就不用看了。高音是银笛的产品。[讨论]
你的阻抗好像不大对阿,哪能10几欧呢![讨论]
您说的没错,我这个高音其实很差的,才20多元,我 把它的相位校正罩给掰掉了,再高音处有一个很大的锯齿,不知是不是它的原因。另外您的箱子体积很大吗,是三分频的吧,高音好像也很一般啊,是什么牌子的?指的是。
频响图的刻度范围。整整用到了100DB,在这种情况下直观性就不强了。略差的频响就都变得相当的好看。其实细看一下。低,高音的普遍都在80刻度以上。而分频交接的地方最低的谷就到了70了。这里就相差起码10DB了。如果刻度调小。这将是一个很深的谷。我一的刻度范围一般都设在40DB。还有可以把时间窗缩短。然后测量距离再远些。目前隐藏了相位曲线。可以把他显示出来。哈。帖个偶这段时间又调整的国产单元的箱子。远场。<img src="attachments/dvbbs/2005-4/2005413203143792.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-4/2005413203143792.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

“范围太大了”是什么意思?说实话,范围太大了。

我未用平滑,看样子还行![讨论]

不用抓图软件。
测量远场尽量远些。先按键盘的PRINT键。然后用WIN系统自带的画图然后粘帖就可。问题是你如何将其转成JPG。XP系统可以直接转换。[转帖]
10毫秒,距离是35厘米,我没有抓图软件啊,改日下一个!什么单元?
频响很棒的说。单元上箱以后的总频响测了吗?
先不要隐藏相位曲线。
时间窗设的多少?什么环境测?把整个屏幕抓张图吧。高低结合远场时的
