Hitachi has
created the metal Cone Speaker because we believe it is superior to speakers made with paper cones. Paper
cones are fine but they have a tendency to respond partially and not
"whole-heartedly" to a signal coming from the amplifier.
In other
words, as the voice coil pushes or pulls at the cone center, part of the cones
respond correctly while other parts don't.
What is
needed is something piston movement. A material with free circumferential
elongation and contraction. The result
of extensive research into all possible (and sometimes impossible) cone
materials. Hitachi's engineers created the Metal Cone with perfect low
resonance characteristics.
Light,rigid,
it also possesses a "gathered edge" supporting the metal cone firmly
without disturbing piston movement.
Altogether producing far less distortions than conventinal paper cones.
It responds
"wholeheartedly" and not partially giving your music full power of
expression.
You might
even say it gives your music an edge.
Paper has
always been the traditional material for even the finest speaker systems.
Unfortunately, a paper cone doesn't move evenly over its entire surface, which
results in uneven frequency and transient response - or "breakup
distortion".
So Hitachi
engineers overcame that problem by using metal cone diaphragms for the woofer,
mid-range and tweeter combined with a peak control circuit which eliminates any
possibility of cone resonance affecting sound quality.
Then, a
patented Gathered Edge suspension design was applied to the woofer which
prevents lateral vibrations causing distortion, while at the same time,
allowing a greater dynamic bass response.
We believe
this unique pair of performers are the most exciting, lifelike, distortion-free
speakers we've ever heard. More
important, we think you'll agree.
