They both beam, are unacceptable above and below the midrange, can't play loud and diminish dynamic contrasts.
JWC had double 9s before the Dayton-Wrights and I accompanied him to visit a guy in Macon who had an HQD system with the Hartley woofers and Decca ribbons.
As for me, the answer to all those limitations is the Sound Lab design. The faceted panels greatly minimize beaming so long as you get a 90 degree model or array. They really do the first and last octaves. Dynamics are more a function of power and panel area.
Ray Kimber put together impressive demos of his Iso Mike recordings using either double or triple arrays of 922s (9 foot tall - 22 degree radiation) or 945s (9 foot tall - 45 degree radiation). My U-1s are effectively "790s" in a steel frame.

You do, however, need some space. Double 945s will fit tall rooms.
