The speaker system developed only for stereophonic reproduction in order to
realize the stereo sound which was able to balance on either side firmly at any
places of the room.
In consideration of directivity becoming tight, acoustic directional control
(radiation pattern adjustment of a unit) united with play frequency so
that a spread of the optimal sound might be realized in any compasses is
performed, so that frequency becomes high.
corn type tweeters are carried in the 20cm corn type Woofer and the high region
In order to improve the linearity at the time of the Koide power,
while adopting very light corn paper, the aluminum ribbon edgewise volume which
made full use of a computer is introduced into a voice coil, and low resistance and a quantity linearity are pursued. It is possible for this to drive
efficiently also in a small magnetism circuit.
A Woofer unit swerves
outside from the center of a front baffle plate, and is mounted. It is possible
to be able to acquire the big reflective effect, to fully raise radiation power
by an inner side with a large baffle area by this, and to emit sound to the
large area of a listening room.
This baffle area is tuned up by computer so
that an effect may demonstrate to an improvement of the zone (500Hz - 1kHz)
where influence begins to appear to directivity.
Before the Woofer, a
tweeter unit gives a separate angle and is being fixed two, wire connection of
the direction turned inside was carried out to the Woofer with the corresponding
phase, and it has diffused sound widely in the listening room by the synergy of
Moreover, wire connection of another [ which was turned
outside ] tweeter is carried out as an object for control of sonic energy, and
it works with a Woofer and an inversion phase, and if set to 5kHz or more, it
has structure which cut the output by the bypass circuit in the zone (1kHz -
The enclosure has dual chamber structure which divided the core
into two rooms.
Air capacity which the subport is prepared inside and
passed,While being controlled by the air resistance in the main port established
in the front baffle and negating generating of standing-wave, air inside the
enclosure is efficiently changed into low-pass, stopping the corn motion of a
In order to make a speaker from the quality as theoretical, the design
and the production process are managed by original computer (cincom III)
developed for making a speaker.
Moreover, in the final stage of a design, the listening comprehension test
staff of included BOSE checked sound with the lug, and has fed back the
artist and the studio engineer to the product.
There was an exclusive speaker stand as an option.
