Handmade speaker basic lecture 06
It makes with a/reader specially D-58ES-R.i
Music Partita of No. 4 Saraband JS. Bach
It makes with a /reader specially. D-58ES-R.i
To a completion of a correction Itadori figure, and the direction
to manufacture sake
Masao ida
In order to make a speaker, the matter is carried every minimum
Please have a look from beginners to maniacs.
D-58ES of Mr. Nagaoka serves as this sound plaza Ida's trademark.
It is a back load phon. It is Fostex to the handling description of
FE208 ES-R.
There is D-58ES of 18mm use of China apiton plywood. It is a reader
to my idea about this.
The idea brought near by you is added and the Itadori figure of D-58ES
made with a reader is completed.
It carried out. A name is set to D-58 ES-R.i in order to distinguish
from
D-58ES of Fostex.
The process of manufacture is carried on this page so that it may become
reference of you, a reader, from now on.
A notice of unapproved printing
The Itadori figure refuses printing without notice found in the text. The
Itadori figures are a part of printings.
It is carrying out. I am passing the direction which manufactures D-58 ES-R.i
and D-58ES.i on our side.
The Itadori figure of D-58 ES-R.i
(1) Change of Itadori Figure
D-58ES of the handling description of FE208 ES-R
Combination of reinforcement is performed for a part of D-58ES of
Mr. Nagaoka, and it is still firmer enclosure.
It has become.
Mr. Nagaoka/Heavens board one sheet -> Fostex/two sheets
Mr. Nagaoka/rear one sheet -> Fostex/two sheets
Mr. Nagaoka/front part two sheets ->Fostex/two sheets
Mr. Nagaoka/side board two sheets ->Fostex/two sheets
Mr. Nagaoka/bottom two sheets -> Fostex/two sheets
Others do not change a lot. 18mm of China apiton plywood is different
after all.
Mr. Nagaoka / China plywood/21mm -> Fostex/China apiton/18mm plywood
Reference: The D-58ES Itadori figure in the handling description
of Fostex/FE208 ES-R
1. Direction of Grain
D-58ES of Fostex becomes front and, as for a curved surface, grain becomes
a transverse direction.
Since a side board comes out perpendicularly, it is sorry about becoming
imbalanced.
Although this becomes like this due to the Itadori figure, I am D-58ES
of Mr. Nagaoka.
I want to have come to make the front into the grain of the same length
as a side board.
Although the design of BB-69mg.iII is also so, since the front is conspicuous,
it is
from the board
As for a curved surface, taking with the same board is good. Then, grain is connected
finely.Furthermore, it is from Unit attachment board 1 for turn to 19.
The Itadori
figure of old
Mr. Nagaoka is so far.
It does not think. Since the curved surface is taken from various parts, I feel
dissatisfaction, and it is very.I thought whether to become.The Itadori
figure of D-58
ES-R.i is created in consideration of the direction of grain.
Since all Unit attachment board 1 2 25-21 of the front are taken, they
are the
same than the same board.
It becomes grain.
17-19 are the stop boards of the weight of a bottom, and become the grain same
also here.
2. Size of Side Board
The side board of a handling description is 570mm. Since true depth is
565mm, it is
exaggerated 5mm.
It is carrying out. Although Mr. Nagaoka was also the 570 samemm, I considered
when D-58ES was made. was more nearly sorry about not suiting 3mm than
the side
board in D-58ES. That is, it is at 570mm.
It cannot make exactly.
Other you think that you are the same. this time -- readers' opinion -- hearing it
-- D-58ES -- more
I thought that it could not but change into receiving.
It decided to change.
Side board 570mm -> 567mm
A 2mm difference is the thickness of a bond. When it was exactly made 565mm
I thought that a side board became short.
A table makes a side board from one sheet, and the reverse side is to the combination
of two sheets.
Mr. Nagaoka side board It is the combination of two sheets a table side. It is the
combination of two sheets a reverse-side side.
It is one sheet -> Fostex/table side. It is the combination of two
sheets a reverse
-side side.
The merit of D-58 ES-R.i is to make the table of a side board from one
sheet. If it
is one sheet
Grain makes it strain oneself.
3. Board of Maximum Bottom
The maximum bottom is the structure of carrying the side board of a two-sheet
pile
If the thickness of a bond is considered here conversely
It runs short in the 432 samemm.
The maximum bottom 26 boards 432mm -> 434mm
4. Hind Board
The rear of Fostex is a two-sheet pile and the outside is made of three
sheets.
This is among three sheets.
There is a crevice. This thinks that a crevice is unnecessary to make it a firmer
thing.
Rear 14 boards 100mm -> 125mm
14 boards 125x2 The board of 15 was set to 360mm by making it 110mm.
5. Position of a terminal
however, the time of connection -- especially -- super Tweeter
-- attachment -- removing -- coming out -- Heavens board
The attachment of a terminal is more convenient.
BH of old Fostex was on the rear. This is the audition room of Fostex.
Although it is good now since it is large, if it is a general room, since
it
is narrow, Heavens board is good.
I want Heavens board to change and to take from now on.
It changed.
On the rear -> to Heavens board
* Make with a reader.
If this Itadori figure does not have cooperation of a reader, it is not made
Moreover, D-58ES is made.
It also turns out well that there is much direction which has passion
in things
very much. Your mail
For making from agreeing with making from 18mm China apiton plywood
and FE208 ES-R
It also turns out that there is much direction to do with China apiton
plywood.
About sound
Considering being able to employ the sound of FE208 ES-R efficiently
further
and losing distortion, it is the plywood for speakers.
It carries out and China apiton plywood thinks the best thing.
Although a price is high, the feeling of using it for years or having
made from
oneself a speaker
It appears also in sound. Therefore, it is recommendation about making from
China apiton piton plywood enduringly.
Moreover, that I can also join the world of such a wonderful handmade
speaker
together with you
It is the greatest joy. As for the Itadori figure of this D-58 ES-R.i,
the idea of
you, a reader, also entered.
It is the back load phon made with a reader.
Since I also make, the photograph of this manufacture process is taken
and
description is also given this time.
Moreover, since he wants to also carry a reader's photograph, you, a
reader,
are very well and please give me cooperation.

The Itadori figure of D-58ES.i
(2) Change of Itadori Figure
Having corrected D-58ES of Mr. Nagaoka differs from D-58 ES-R.i.
1. Direction of Grain
Grain is finely connected because a front curved surface takes 5 6 1
17-14 from
the same board.
It was made like. 26-24 have also taken the stop board of the weight
of a bottom
from the same board.
2. Side Board / Bottom is the Same as D-58 ES-R.I, and Side Board Corrects
Bottom
to 444->446Mm 570->567Mm.
It carried out and it was considered that a crevice did not come out.
A table makes a side board from one sheet, and the reverse side is to
the combination
of two sheets.
Mr. Nagaoka side board It is the combination of two sheets a table side.
It is the
combination of two sheets a reverse-side side.
With ->D-58ES.i It is one sheet a table side. It is the combination
of two sheets
a reverse-side side.
The merit of D-58ES.i is to make the table of a side board from one sheet.
If it is
one sheet
Grain makes it strain oneself.

3. 18mm of China apiton Plywood
With the plywood which carried out the laminating of the China material
and the
China apiton material by turns, it is soft sound to the China material.
On the sound target which compensates with the hard sound to China apiton
material mutually, and is compatible in tension and softness
It is the outstanding plywood. Compared with the China plywood, about 30% is
heavy, and since density is high, it is the former.
The thing more than equivalent can make 21mm of from 18mm.
If it strikes, how is it?
There is heavy sound. China apiton piton plywood is like [ in the China
plywood
/ although it is light
There is sound. There is no Since it is very hard, it is personally difficult
to
vacate the hole of Unit attachment board or a terminal.
Moreover, since sandpaper is tight by hand, its electric Sander is convenient.
The feel of 18mm of China apiton plywood is tried from 4/21 audition
meetings.
============================================================
* Rather than 4/21 audition meetings
it has put on the audition meeting of FE208ES-R.
Please look at the FE208ES-Rpage
