各位，对于音箱设计软件的BASSBOX和LSPCAD:
请各位给一个性能或功能比较和目前的大致的价格。
如果一个小的音箱厂，选用哪一个好？
谢谢！

谢谢水仙超版了！
看来，这些软件也是有学前班、初级班和高级班一样的差别的。
先从简易的开始，“等积累了利润”和知识后再升级了。
Thank you very much !

以下是引用DAAS在2010-10-25 17:37:21的发言：
准备自己上了？
多面手，牛人也。
哪里哪里！
只是先前没有机会（其实也不必要）去用这些软件去设计音箱，大不了就是手工计算或交给别人代工，慢一点也就是了。
那些前辈在没有这些软件前，也得设计的呀。
先手工，后计算机辅助，可能也是一个必然的路。
买了软件，会有人去用的。而且，总得有一点家底吧？
