The guy behind many Dahquist designs went on to form Alon, and now Nola. I'm sure I cant spell his name, even if I could remember it correctly! I believe "open baffle" describes the 20s, not sure if the are considered bi, or dipole? The 8 is a two way, with the woofer in a box and only the tweeter on the upper baffle.
Very creative designs for their day, Dahquist, Alon and now Nola all highly regarded.
