|DS-10000 is the speaker with which
DIATONE commemorated and put the 40th anniversary on the market.
is another about this model and the page is prepared, I would like to write the
contents which it delved into a little more deeply about this speaker here.
As you know, I regard as or that DS-1000 is adopted as the
base of DS-10000.
It seems that it is reasonable in DS-1000, such as DS-3000
and DS-2000, having been chosen as the base as it is.
It seems that DS-1000 was considered to have a high possibility after a
system constitutes [ basic ] by the Diatone of those days. It seems that
it was a form where even the critical point which is already hard to move
was boiled down and completed, and it was large in basic composition that
the data used as a base was also assembled.
There are a Woofer and a talk of if 30cm was better. However, seemingly
that a 27cm aperture was adopted is the size which came out of the necessity
of being 3 way composition. It is a thing that it was decided from the
conclusion "the height of fundamental quality has that the small caliber
is [ much ] better than a large caliber." (This may be the reason
DS-20000 and DS-20000B also carried out 1000 systems at the base) .
Moreover, it is the result of even an acoustic radiation pattern being
examined by computer analysis also about unit arrangement at a research
|Then, let's see about each composition part.
||It is general drawing of a tweeter.
The most different feature from DS-1000 is that the boron D.U.D diaphragm
has "three-step iris diaphragm structure."
IDS-1000 and appearance are [ sub-frame ] alike. However, unlike the product
made from a brass of DS-1000, a gun metal began to delete and the workpiece
is adopted. It seems that moreover, it has structure which differed in
details. It seems that the high region play in which a reverberation is
thereby still more beautiful is enabled.
The felt for vibration suppressions is stuck on the

three-step iris diaphragm was developed by DS-5000, the rigidity of a diaphragm
goes up it, and there is a merit to which a high region play limit is extended.
IHowever, seemingly the very hardness thing was required by production
technology and adoption to a mass-production model was not completed.
It is only DS-10000 and DS-5000 that this three-step iris diaphragm is incidentally adopted in the range which I know. The same limited model is not adopted as DS-20000 or DS-20000B, either.
||Cork material was stuck on the frame made from a gun metal, and degradation of the signal to noise ratio by the unnecessary radiation of a frame part is prevented.
||It is general drawing of a mid range unit.
Back covering is fabricated by the hand iris diaphragm (method of spinning), in order to make it distribute structurally so that vibration mode may not concentrate on one place. Moreover, the number of attachment screws is also changed into eight from four of DS-1000.
Incidentally, in DS-1000HR put on the
market after this, it is being similarly fixed by eight.
||It is the sub-frame and back covering of DS-10000 and DS-1000.
Structures differ not only in a difference and the method of structure of a
material but in the fine portion.
||It is general drawing of a Woofer unit.
Although appearance does not have other DS-1000 series and great differences,
each is pressed by hand structure and the delicate curve of an aramid honeycomb
corn is the feature.

The material is changed into the aramid (Kevlar) by DS-10000 from the
polyamide of DS-1000.
The honeycomb of the aramid was used for the antenna
of an artificial satellite etc.

For every unit, it is divided and is attached to

The radial supplying system to each unit
which supplies electricity radiately from an input terminal for proper current
supply is adopted.

Because the 1000 same systems were made piano paint by glimpse as there was a prejudice especially in the enclosure although the processing which was very scrupulous also about each unit was seen, it is visible, but it has structure appropriate for a limited model with which the hand was very much crowded.

screw at the baffle plate.
Moreover, in order to realize the outstanding
signal to noise ratio, the rubber cap is attached to the attachment screw, and
the resonance is suppressed thoroughly.
It is said that the frame and the
screw "resonance" are used as part of the production of sound in the common

felt is stuck on a pleuron side on the whole surface, and it fills up with wool
yarn 100% of the sound-absorbing material.
In the glass wool currently generally used, seemingly the hysteresis noise
which a sound-absorbing material emits will soil the sound of the speaker
itself, and this material was chosen.
||The left is a cut photograph which the
difference in the composition component of the enclosure understands.
It is said that pleuron sandwiched the hard chipboard by the multilayer
laminate of the China material, the baffle is using the lumber core material
of the Sitka spruce, and the Naked material of Matoa from New Guinea used
for grand piano etc. is used for the attachment structure material of an
aspect-of-affairs part and a baffle.
All the materials are examined one by one, and they are used,
selecting them carefully truly.
Moreover, a right photograph is a cut

From here, I see about the data at the time of the development
published with the magazine etc.

At the last
There is DS-10000 as it commemorated the 40th anniversary and was made, and it differs from the 4-figure series as which mass production nature was considered to some extent. Being conscious of musical instruments, such as a piano, it is a thing adhering to the material and combination of the enclosure, and if it is not limitation, it has the extravagance which cannot be made.
