Great stuff, and very nice build quality all around.
Above all, they don’t sound like a commercial speaker. You know the feeling when you listen to an all B&W or Focal or McIntosh speakers and feel like you could recognize them in any room? You can’t really tell mine. They lack treble "character." They sound effortless without the excess air of say some ribbons as well.
Those tweeters are AMT’s, right? I have a pair of used, active speakers soon to be implemented in my setup with a "ribbon" or rather planar magnetic tweeter/midrange driver (if all goes well with the intention of replacing my EV’s), and having heard the same driver over sibling models I find your description to match my impression of these as well; something appears to be missing initially, but over time it becomes clear what’s really lacking is a combination of coloration, smear, strain and other "effects" heard from other types of drivers. There’s also limited vertical dispersion, and so no boundary "help" to speak of from ceiling and floor, which may contribute to their overall imprinting.
The 10" Dayton woofer is a cool looking driver. I once considered a 15" version of this driver for a front loaded horn subwoofer, but eventually wound up with a different design and driver.
