Hi, I just got a pair of Reference 3a M3 Generation II and would like to retrofit the tweeters. From what I've found, it look like its a Vifa D-26TG.
What is the best retrofit and do I have to modify the crossovers ?
many thanks

What are you trying to accomplish by retrofitting the tweeters?
From what I know of Reference 3a, they use a 'minimalist' design philosophy, running hard cone woofers without filters, well into their cone breakup range, and a single cap on the tweeters. I believe they voice everything by ear and don't put much stock in measurement or modeling. I stand to be corrected on their design process, but the measurements I've seen certainly seem to be in line with that.
If yours are similar, and you want to stay true to that philosophy, then you can likely just tweak the tweeter cap and level to taste by ear, and end up at an equally 'valid' result.
It would be an interesting exercise to design a modern measurement/modeling approach crossover for these speakers, and frankly, I'd expect that to be where the biggest SQ gains are to be found. But that would not really be in keeping with the R3A ethos as I understand it.
