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.

HANIWA 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.

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 definition.

HANIWA speakers are unique in that they are:
- 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 restriction

HANIWA speaker cabinets are the result of tossing convention out the window and focusing on the basics of audio physics theory. By avoiding traditional thinking, KUBOTEK was able to arrive at an optimal cabinet shape and construction --- made possible only by Kubotek's own proprietary 3D CAD/CAM design and manufacturing technology.
