Dispersion Concepts
In the field of loudspeaker design, it is
common knowledge that as the wave
becomes progressively smaller than the
transducer producing it, the dispersion
of that wave becomes more and more
narrow, or directional. This occurs as
long as the transducer is a flat surface.

exclusive, offers optimal sound distri-
bution with minimal room interaction.
The result is solid imaging with a wide
listening area.
Even though they suffer from "venetian
blind" effect, angled multiple panel
speakers can deliver good imaging,
but only to specific spots in the listen-
ing area.
As can be seen, point source concepts
invite a great deal of room interaction.
While delivering good frequency re-
sponse to a large listening audience,
imaging is consequently confused and
blurred.
Historically, most attempts to achieve
smooth dispersion from large flat panel
transducers resulted in trade-offs. After
exhaustive testing of these different
solution attempts, we found an ele-
gantly simple, yet very difficult to execute
solution. By curving the radiating
surface, we create the effect of a
horizontal arc. This allows the engi-
neers at Martin-Logan to control the
high frequency dispersion pattern of our
transducers. That is why you see the
gentle curve on our products.
