Since I've stripped one of my Mar-Kel70 speakers I needed a new set to use while I finish my Mar-Kel70T. I decided to grab some old speakers I found in the cellar, some Zachry dipole/bipole (I still don't know the difference! :P). But at the first song I realise something is wrong. The cymbals and high frequency stuff only comes from the right speaker. With some help from my ears I find that three of four tweeters appear to be broken. I opened one of the speakers to see if there were any loose cables but everything seemed OK to me.
This is what they look like, another pair of drivers on the other side too.
