The speaker system which introduced the bipolar
technology in order to improve a directivity.
A directive large speaker
unit is arranged to an order baffle, and it is driving by the corresponding
By a rear surface release type die Poral monotonous speaker, since it
generally became a plane wave of an order opposite phase and was strongly
influenced by phase interference, realizing such large directional
characteristics was not completed, but the diffusion property almost near a
360-degree undirectional has been acquired with this technology.
3 way 6 unit configuration.
In each band, the quick transient and the hyper-polic dome tweeter which
maintains a low-distortion flat response are adopted as a high region over
the directing span of 180 degrees. The high-speed response wide band mid
range by the carbon addition polypropylene low-mass cone of a three-layer
lamination is adopted as the mid range. The special treatment was given
to low-pass and the high input-proof long stroke Woofer of carbon addition
polypropylene, a nitril PVC edge, and an aluminum voice coil bobbin is
adopted as it.
An enclosure makes full use of a CAD design and CAM processing
technology, and is suppressing the size error to ±100 microns.
Moreover, the high-density fiber board was used and the occurrence of a
peculiar vibration and a stationary wave is eliminated by a special splicing
structure and internal septum, and solid angle reinforcement.
avoid the influence of a diffracted wave, and are using it as the flush mantle
sunk into the baffle side. Furthermore, a corner is considered as curved surface
finish, and it is being fixed that there is no gap in the same planar as a
baffle so that a grill cross may not become an out-of-order of a good diffusion
Kibe's surface finish serves as black gross finish.
The network part is developed by Computer modeling in order to secure
the neutral response and tone balance over an omnidirection 360 degrees.
Furthermore, a careful selection part is combined and it is tuned up by the
careful listening comprehension test.
Moreover, the input terminal supports
bi-wiring / by amplifier.
