I have a friend who has a rather expensive set of speakers. He bought them used and the shipper dropped them on delivery. That was a while ago. The problem is, there does not appear to be any significant midrange in either speaker. The treble is good as is the base. It is almost like there is no midrange at all....changing amps has no effect nor does moving the speakers...

So, my question...what can kill the midrange on two speakers? Do makers use multiple fuses so that one failure would not shut down the entire speaker??

I cannot think of anything else. Apparently the drop was enough to damage both tweeters so as to require replacement but nothing was apparent with the mids.
