Is each tweeter at a different crossover point, or just some of them? Will the crossover point make each tweeter in the same cabinet seem at a different output level? If so, will the crossover and ouput level in one speaker mirror the other speaker? For instance...if the bottom tweeter has the highest output level in the right speaker, will the highest output level tweeter also be the bottom one of the left speaker. I hope this makes sense.
Anyway, I started to notice the sound of one speaker started to dull a bit and things in mono didn't sound even. I turned down the bass, boosted the treble and went to each tweeter with a tube to my ear. I noticed that each tweeter had a different level in the left speaker and in the right speaker I found the thrid from the top tweeter to be dead. I checked it and it's a gonner. Now the working tweeters don't seem to exactly match their buddies in the other speaker, but they also don't appear to be damaged. Kind of like they're in different position than the other speaker.
Also, since upgrading all the tweeters isn't in the cards at the moment, does anyone know where I might be able to locate a working SL3000? I'm sure the RDO replacement wouldn't be the best fit unless I was changing them all.
