求救，音箱在摔坏了，还能修吗？

dreaman

由于搬家，不小心把我的一只JM Lab音箱摔了一下，结果两个单元的磁钢都摔断开来了。。。。这样的情况还能修吗？

虽然是旧音箱，但是用得不多，摔坏了还是非常心疼的！型号是Focal JM Lab CHORUS LCR700 书架箱，请问如果换单元的话可以修复吗？我也不要求他的音质能恢复到以前，但是剩下另外一只孤零零的也用不上啊！[s:16] [s:16]

刚才在网上仔细学习了一下，单元的型号和参数也抄下来了，应该是只要买得来然后再焊上去就可以了吧？？


唉，看到ebay上1月份有人卖一对这个单元，倒是不贵才拍了300多元。就是可遇不可求啊！！！唉！
