Seas Excel Millennium Tweeter

They aren’t running out. :)

You can always buy one now and one later.

It is worth looking at the crossover however, make sure there are no burn/scorch marks or bad resistors.  If so, you should deal with that on both speakers before installing a new expensive tweet.

@erik_squires ,  the new one once broken in should sound nearly identical to the other one that has played for awhile, no?

@chju1986, how did that one tweeter go bad?  Nice speakers by the way!  While you are in there take a look at the crossovers.  It might be a nice upgrade option.  Those are awesome drivers, some of my favorites

@b_limo, I think so.

The break in issues I've experienced have been with mid-woofers, woofers and caps.  Not tweeters.

@erik_squires, The crossovers look good, I thought about modifications but I like the speakers to much as is!! My "gut" feel was there would be minimal break-in on a tweeter, but never having to replace one, truly value other opinions against my ignorance.

@b_limo, good question on what made it go bad, no clear indication.  I noticed a couple pops from my Music Reference RM10 amplifier, one for each speaker, at which point I rolled a few tubes.  It was shortly there after it was very clear that the tweeter was not working. Also in the circuit are a Tom Evans phono and a Blue Circle Attenuator.
