Come a long way yet?
I am actually sbout to finish a pair, two pairs actually, of stereo speakers buils from ground up with Tang Band elements.
Not the crazy excursion ones or the full tones, but with their "normal" 6,5"s and 1" tweeters.
During build i had them in-house to adjust the x-over and to hear the sound and it was fairly good being being hooked up to my first x-over design ever..
Thay werent too far behind sq wise from a pair of speakers running Seas elements at 3x the price.
