EF Series Has Been
Upgraded for Higher
Performance!
The PMC (Polymer-injected Mica
Diaphragm) Series was a great
success, proving popular with
consumers and winning awards
for excellence around the world.
The new EF (Elliprical Form)
Series is designed to build on
that success, offering even
higher performance combined
with an elegant Yamaha
traditional piano finish cabinet.
The woofers, tweeters and
cabinets have been refined and
improved, and even the wiring
has been upgraded, with
Monster Cable being used to
connect woofer and crossover
network. The result is superb
audio quality with music sources
and the latest 6.1 and 5.1
channel movie soundtracks. It’s
the latest in home theater
speaker design, from the leader
in home theater: Yamaha.
Behind EF Series Superiority: the
Waveguide Horn
Conventional direct-radiating home
speakers have broad directional
characteristics that result in a
relatively high proportion of reflected
sound (you hear a lot of sound that
has bounced off walls). Movie
theaters, however, are designed to
have a highly absorptive acoustic
environment so multichannel
soundtracks provide a rich sense of
spatial expression. To achieve the
same effect in the home, therefore, it
is necessary to use speakers with a
direct/reflected sound ratio quite
different from ordinary audio
speakers. This is especially true in
multi-speaker home theaters, where
there would otherwise be lots of
reflections. Yamaha accomplished
this with the development of the
Waveguide Horn, creating the ideal
home theater speaker.
