Changing Tweeter on Olympica 3

Theoretically, changing both is best, but I understand that there will be diminishing returns by spending the extra for the 2nd replacement.  

You can replace one and not worry about the 2nd, or maybe you could replace both, and sell the one that's still working to offset costs.  

@knotscott  that could be a good idea selling the older/working one. Not sure how much I could get for it and could take a while to sell.

Fine Sounds insists that both dont need to be changed. As long as a 200 hour break in is done on the new / changed one, it should be fine.

@mofojo

I’m with him on this. I am guessing the difference after breakin will be unnoticeably small. 
 

One of my jumpers came off my speakers so I only one woofer was working on one side and two on the other. It slowly dawned on me over a couple hours of listening that my system was bass shy, but not that there was a woofer problem. I decided to move them back to reinforce the bass and found the offending wire. Very different, but small channel differences are not really appearing. 

Why not just change one and see if they sound different?

If they don't, then it is up to you to decide if the cost of replacing the second one is worth it.

@tony1954 thanks, I may do that. Based on what they are telling me, I should not hear any difference. I will need to wait 3 months to get the part anyway.
