我个人的看法!
其实坛子里来这样一件作品很不容易,我关注这个帖子也比较久了.由于前一段时间在忙ZEN-4,所以今天才有空来谈谈我个人的看法.我个人只是业余爱好,好话就不多说了,在此给老兄挑点刺.
1:高音单元的选取似乎不是很恰当,因为灵敏度差太多了.110分贝的90分贝的灵敏度相差20分贝,假设衰减21分贝,那么高音所获取功率只相当于加在衰减网络上的功率的1/128.估计声音和阻尼状况会产生相当的恶化.
2:-24DB/OCT的分频器对单元频响曲线的影响与理论计算的偏差是比较大的,加了阻抗补偿以后就好多了,老兄不妨一试.<img src="attachments/dvbbs/20047162135495915.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/20047162135495915.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/200471621351782959.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/200471621351782959.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
3:关于分频器的用料,电阻电容接线之类的的,自然是高级一点比较好,但是还有个声音的一致性和匹配问题.只要是HIFI界口碑不错的箱子,用料都还不至于很差.但是对于电感的看法,我也是经历了鄙视磁芯电感--崇拜空心电感--理性看待磁芯电感这样一个过程
4:现阶段我们有条件上测试了,我现在也在准备着学习测量,相信到时候对业余条件下的音箱设计会有一个全新的认识. |
