Directivity in Loudspeaker Systems
http://www.gedlee.com/downloads/directivity.pdf
" While the examples shown here for competitors speakers are not ideal and one could argue that they were all poor
designs, I do submit that they are more typical than unusually bad examples. Could they be improved? Of course. Could
any of them ever equal the Summa? No, that is simply not possible. Each one of them has built-in design flaws that cannot
be circumvented without a complete redesign of the system. Basically no loudspeaker which does not use a waveguide is
going to be able to match the Summas performance. Piston source loudspeakers simply cannot do what a waveguide does.
But all waveguides are not equal either. The Summa has a particularly high directivity, which is desirable in a small room
(another topic altogether). There are also other aspects of a design that were not touched on here that play unimportant role
in sonic perception, most notably dynamics. But the fact remains that without getting the polar aspects right, the system
will always be sub-optimal. "
