Eric, Thanks for the advice. I know tweeter unsoldering/soldering can be unforgiving work. I will give this careful thought before changing a speaker I'm very happy with as is.
What would be really helpful is if you might describe the differences you heard as the crossover evolved. My unit was produced around 3/2017. How would you compare the sound to a current production DI? As you and many of us have said their are clearly subjective differences and we all have our preferences. So I'm more interested in the objective differences. Would be a shame to do all that work only to realize I might be in the minority that preferred the original crossover!
Thanks Eric.
