Which 2 acoustic guitarists, I know a few acoustic duo groups....
Brother, my sampling of drivers is pretty small in comparison to the others commenting so I’ve been watching and reading but I think the logic in finding a ballsy low Fs tweeter sounds like a viable solution. I sure wish I could tell you about the Evil 1’s but I am unfortunately awaiting word on another aspect of my build before I can/will install the rest of it. They’ve got an awesome low Fs and it seems like everyone has really liked them so far.
