To @jmeyers - really good speakers, capable amps, all seems in place. I’m very interested how this turns out after the long burn-in cycle is done.
Both @hilde45 compared notes some a few years back, and I have run into this whole "be" tweeter matter before. Recently went to a friends house and changed out some alloys for soft domes for him on some speakers I made years back.
Some designers have even walked away and back to really good soft domes. However, I tend to believe the right crossover design could help, but that’s a guess too. An adjustable one [dare I say] but may be unique to each persons system, room, etc.
Also, meant to ask, are you running "silver" or silver over copper interconnect and speaker cables by chance?
Keep us posted here to let us know how it turns out, okay?
