|Tractrix Horn creates a Virtual
Point Source of Sound ::
The heart of the
unique HANIWA speaker system is our own proprietary version of the
classic Tractrix horn shape. Unlike conventional diaphragm type
speakers, horn speakers use compression drivers to reproduce and
focus the sound to create increased sound level pressure --- ideal
for reproducing the sharp transient wave form which defines the
tone of musical instruments and other sound sources.
speakers feature "Spherical Horn", evolved from the
classic Tractrix horn design to include a smoothly rolled horn
mouth edge, ideal for releasing sound and eliminating the
unnatural sound deflection found in traditional horn designs that
create audio image "ghosting".
With Tractrix horns, a
"virtual point source" of sound is formed at the center
of horn mouth. In HANIWA speaker systems, this virtual point
source is lineally aligned between the woofer and the tweeter,
resulting in a clear, horizontal definition of sound.
Because all HANIWA speakers use
horns, they are remarkably efficient, reproducing sounds with a
small stroke that can be driven by low power. The result is
astonishingly accurate sound reproduction at a volume levels with
dramatically reduced distortion.
|HANIWA Speaker Enclosure ::
The unique appearance of HANIWA
speakers is derived from the fundamental concept that the cabinet
should express audio theory naturally, based on the spherical
shapes. This differs substantially from traditional cabinets which
are restricted by conventional manufacturing methods.
The principle behind the radical cabinet design
is that the speaker enclosure should never vibrate --- if it does,
the enclosure itself becomes a sound source and adversely affects
the clean, accurate, and vivid reproduction of music. That's why
the HANIWA speaker cabinet is carved out from a solid laminated
block, strong enough to suppress any vibration; the interior
structure is designed to avoid resonance and reflection,
minimizing bass sound leakage through the cone of the woofer unit.
It also feature a short bass horn with an active crossover to a
mid-range horn for a full, well-balanced low to mid-range sound.
The cabinet is also designed to layout high,
mid-range, and bass sound source in a line, and to minimize
distances among those sound sources. By that, the three output
signals are closely aligned for a sharp, horizontal sound position
HANIWA speakers are unique in that
- Completely enclosure - Made entirely of curved surfaces
- Based on the precise Tractrix curve horn shape
- Designed and manufactured by full 3D CAD/CAM system with no shape
